When Paccar introduced their own motor, they told Cat that they would still install Cat motors, but Cat had to do all the engineering/design work for installing the motors at Cats expense. That along with losing market share to the new Paccar motor helped drive the nail in the coffin. I sold my 03 Peterbilt with a perfectly good 6NZ Cat when I ordered a 14 Pete with the ISX500 Cummins. All other drive train components the same, and went from a 379 to 389 which is the exact same body style. The difference is a mile per gallon less (5.4 verses 6.5). Add on having to pay for dpf, poorer performance, and very expensive repairs for sensors, dosers, gate valves, and God knows what else, plus adding for down time, and you you understand our frustration. Now they are trying to push "eco tires" that cost more, wear quicker, and don't increase fuel mileage one bit. Who the hell comes up with this crap? Government people with no brains. That's who.

[@peteheyde7999]

As a retired OTR driver for 40+ years, I can tell you that your account of why Cat stopped selling road engines is spot on dead nuts accurate. From 1994 until 2014, I was driving for the country's largest private fleet and we were testing Cummins, Detroit, Volvo and Cat engines side by side. The first 3 engine manufacturers went with the EGR setup. Exhaust Gas Emission Recycle valves, better known as EGR valves, meet emission standards by putting exhaust components back through the engine. This is regarded as a contentious issue because putting "dirt" back into an engine will invariably shorten engine life and although it statistically resulted in engines meeting emissions standards, it also DECREASED fuel efficiency. I seriously don't understand how an engine can burn more fuel but pollute less. It seems like the government the wants us to believe a lot of things that don't make sense. In any event, Cummins, Detroit and Volvo opted for the EGR method. Cat had a huge canister in the exhaust system that we were told worked like a heavy duty catalytic converter. We were also told that the Cat engines DID meet emission standards, but the EPA mandated that Cat HAD to follow suit and use the "dirty" method. I can't comment on the warranty issue that Cat was allegedly having, but in terms of division profit percentage, that 10% figure alone would justify the truck engine discontinuation. Regardless of the actual causes, I was impressed by the fact that Caterpillar in effect "flipped the bird" to the EPA. Let businessmen, engineers and technicians do what they do best: make a good product at a fair price and profit from that. Conversely, the government is inefficient, wasteful, overbearing and technically ignorant. As such, it would be much better for us all if the government would get the EFF out of everyone's way and allow America to ROAR again!

Now in 2007 is where that changed because in order to meet those updated standards they did have to throw on a dpf which included their Infamous ARD head device as well as a CGI system which is essentially a better version of standard egr

[@JosephArata]

The ignition spark plug in the exhaust "ARD" was their folly, that's the system that made them have countless warranty repairs. Because anybody knows you can't expect something like a spark gap to work to ignite extra diesel in the exhaust, when the exhaust coming out of the engine is already black soot laden, as most C13 and C15s always ran rich.

Why is there a new vid on this every couple weeks? Basically, it takes a lot of time and money to design and build a new engine. The gov promised cat a period of time say 8 years where emissions regulations would be the same, but they kept going back and changing their mind. Every politician wants to be more virtuous than the last, so it went from 8 years to 4 and down to 2 year intervals. Making it not financially viable for them to keep redesigning only for it to be redesigned once production started. Long story short, gov ruins everything with red tape and will burn down your house for a crumb of good publicity.

[@RageRover]

I could be wrong in some aspects about what I’m typing here but….I do believe the partnership between Navistar/International and CAT didn’t just create an on road truck that kinda met emissions standards. I think CAT either sold rights or just allowed Navistar/International to take existing CAT motors and then adapt them to meet emissions standards by adding components such as EGR, DPF, DOC and SCR with a urea system. I’ve seen these motors before in International ProStars and LoneStars. If you carefully examine the motors (Cummins is an exception) you can see the architecture of the motors are that of the older CAT motors that were of the ACERT generation only the motors aren’t CAT yellow in color anymore. Instead Navistar branded these CAT motor knockoffs as MAXXFORCE engines with the latest emissions components that Navistar offered on other of their engines. But the basis of those larger engines was the pedigree of CAT. I think Navistar used what was the CAT C-15 and C-13 engines for the base of their larger MAXXFORCE engines.

[@curtisnoble.]

Maxxforce 15 had Cat bottom end. Maxforce 13 was Man engine with Navistar emissions. C13 was Cat engine with Navistar Head and electrical. N13 is “fixed” Maxxforce 13 with proper emissions A26 is the New Man Engine.

[@curtisnoble.]

And I think the Maxxforce 15 is underrated engine with less problems then the 13

[@dmandman9]

Side note: Navistar nearly ruined Ford as well once they had to build an emissions rated engine. It seems as if they met emissions but cut corners in other areas which reduced reliability. Seems like Navistar was the wrong partner

A few years back I had a temporary job driving for a company that only bought new trucks to expand their fleet. The old trucks were rebuilt rather than replaced. Sometimes I got to drive very old trucks. Even though they were maintained on a high level. I can't believe a truck with millions of miles on it would be better than when it was new. However they drove exactly the way I remember. Much better than any of the new trucks. Many had cat engines in them but all of the old ones ran much better regardless of who made the engine. It's not just the engines though even the old dashboards and controls were more logical. The old trucks were simply better. Of course none of the old ones have those damn auto shift transmissions.

CAT did actually adopt an Exhaust Particulate Filter and EGR in 2007. The problem was that they sucked. The R-Heads which is used to raise exhaust temperature to burn off the soot in the EPF keeps failing. Part of this is because they only had 3 years to get their EPF shit right, whereas the competition had been doing EPF for 7~8 years at that point. They also did EGR in 2007 and their EGR system is actually quite good -- it draws "clean" air from after the EPF rather than dirty air from the exhaust manifold. But, they kept the variable intake valve duration system which means their engine is more complicated than the competition. Ultimately, the 2008 recession and the lack of profitability on the commercial truck engine line lead to the executives cutting their losses and pulling the plug on this part of of CAT's portfolio. Because the decision was made to exit the market about a year and half into the 2007 emissions compliant engine line's life cycle, the R-head system was never fixed because additional engineering investment in a dead-end product no longer made sense. -- It's a sad story of environmental extremism killing our own industry.

[@dzee7936]

What I learned from this video by quoting and paraphrasing your narrative: 1. Rewinding the clock back to 1990 (32 years ago), emission standards were put in place on Diesel engines requiring 1994 models meet those standards. 2. When new emissions standard went in place in 2002, Cat rejected them and instead paid a fine to not change. 3. It wasn't until 2007 (17 years later) that things got much tougher. (Wow, somehow others responded in time, but Cat didn't see this coming) 4. Cat decided to use a very different emissions system (ACERT) than everyone else. 5. Cat made a huge investment in ACERT betting it was superior to EGR for emissions and ultimately it wasn't. 6. All systems had to be certified by the EPA to meet the emission standard. (This is not simply a matter of writing a check. It must meet the standard.) 7. Cat had tons of warranty issues with ACERT-equipped engines. 8. They lost market share, mostly to Cummins. (no doubt because who wants to have your engine in the shop rather than using it?) 9. Those two things made it barely profitable to build on-the-road truck engines. 10. 2010 standards would be even tougher (and apparently they hadn't yet met the 2007 standard). 11. In 2008 they announced they would leave the market in 2010 and team up with Navistar. You then clarify they didn't simply switch to ECR because it didn't make financial sense. It might fix emissions but not market share loss and warranty costs for ACERT engines. Everything about this says Cat went out of business because of bad choices and delays while their competitors stepped up. Had Cummins followed this path, making the same decisions and suffering the same effects of warranty costs, reliability issues, and market loss, they would have been out of business instead. Conclusion? Emissions standards resulted in Cat's exit from the on-road-engine market. If that were true, why are their competitors still in the market?

[@johnsnow5255]

They made a mistake, cut their losses, and are doing quite well in Marine and Oil & Gas.

Exactly my takeaway. Other companies could innovate, compete and meet emissions standards. CAT could not.

I’ve been working on diesel engines and related components since 1989. Anything from military vehicles to locomotives. To be fair, I have never worked on construction/agricultural equipment. I started working for KW around 2002, and I remember all of those years. Short story, you are correct, mostly. Caterpillar had a “good idea” of sorts when the government announced new EPA regulations for OTR commercial vehicles. While everyone else was outfitting their engines with EGR ( exhaust gas reduction) systems, Caterpillar went a slightly different way. You see, EGR redirects a portion of exhaust gas back into intake air, which, introduced soot and carbon into the intake. Caterpillars idea was called CGI (clean gas induction). They filtered their exhaust gasses through the DPF BEFORE redirecting a portion of it back through the intake. The major problem with their CGI system, it eventually produced a yellow powder at the precooler, which when inevitably water was introduced through condensation, would form an acid that ended up being worse than the carbon and soot every other manufacturers engines were being force fed. Caterpillar HAD the better idea, it just never panned out and they NEVER met emissions standards. I hated losing Cat engines, I enjoyed working on them. And I can’t tell you how many problems Cummins has had with their EGR systems, and continue to have. Carbon packing of the pistons being one of the worst. Cummins had their fair share of warranty expenses too. They just weathered it better because ultimately the Cat guys had no better choice after Caterpillar dropped the ball. And to be fair, Cummins has come along ways. Their engines have gotten way better. And the product support I see on a daily basis as far as warranty goes, is top notch. As far as Paccar engines go, well, they have gotten better as well, and their product support is definitely on par if not better than Cummins is. Let’s just say they’ve still got a long way to go though. Love them or hate them, Cummins and Paccar ARE your 2 best choices on the road today.

You are forgetting a major factor. Remember "back in the day" when truck engines had split power ratings? All the engine companies set their engines to produce more power and therefore more pollution when they were using cruise control. They were all very open about it as well. The thinking was pollution was more harmful in cities where there were more trucks, but you wouldn't use cruise. after the fact, the EPA made this a retroactive problem. Part of the settlement was that the 2007 and 2010 standards were moved up beyond where they were originally planned to be implemented. another part of it was a monetary fine. That fine was based on the company's ability to pay instead of levels of pollution. Cat as a company was fined much more since they had their 90% of the company paying for the fine picked up by the 10% of the company. That's gotta hurt.

I think more thought needed to go into 'assigning the blame'. A lot of the new rules were mandated by a bi-partisan Congress due to the ability to massively improve diesel emissions over a period of years, while progressively lowering emissions through technology. This is a good thing for anyone with lungs! I learned about this because in my job I had to specify back-up diesel generators and there are standards and exceptions to standards depending on the use of the equipment. I think this is a worthwhile subject to talk about, but in this case it was oversimplified. For those who think the emissions rules are somehow 'bad', visit Beijing or Mexico City during an inversion. Lungs do not appreciate nitrous oxides and they can't get rid of soot.

ACERT also had problems with Diesel that wasn't exceptionally clean. There were many places in the world, like Eastern Eaurope and South America that didn't have the infrastructure to deliver fuel that was clean enough. The sulfur content had to be very low, or it would eat the injectors. Also, ACERT couldn't run on biodiesel. The esters in the biodiesel would eat the injector seals right out of them, and cause the injectors to gum up and clog. And forget running on Kerosene or modified olive oil. Not even. Some of the fuel system warranty issues were with the system made by the truck manufacturer. In short, ACERT was damned finicky.

Cummins for example, if you have a pto, or your driver insists on idling his truck a lot, The egr system will soot up your oil and wipe out your bearings. Taking a million mile engine down at 300k. The DD's have a very expensive "one Box" that will shut the truck down for any little thing, internal failures of the box are common and it takes months to get a new one.

There are lots of aspect that come into a company deciding to leave an important market. One of the aspects that is talked about is that Caterpillar had determined there was no way forward to reasonably expect to have long term reliable conventional Diesel engines meet tier 3 Diesel emissions starting in 2010. That is in practice is what occurred. All the Diesel manufactures had horribly running tier 3 emission engines that were very unreliable and the Diesel engine manufactures appear to have all been doing software tricks to make their engines to meet emissions during the tests and then change to other settings to provide marginal drive ability by defeating the emission restrictions. It wasn't until unconventional Diesel engines were mandated that use DEF needed for Diesel engines to meet the tier 4 emission standards that Diesel engine were able to have drivability and reliability. Now that tier 4 emissions are in effect for off-road diesel use in the USA and Cat meets these emissions people are wondering what is holding Cat back from certificating their Diesel engines for on-road use. Cummins really seems to have USA on-road Diesel emission system working at a very high level. Cummins Diesel emission system parts are found on the DD series of Detroit Diesel and MX series Paccar Diesel engines according Diesel mechanics. That might have changed, but the reports are when getting a DPF for a DD engine opening the box would reveal a part that said Cummins. Volvo is the only other on-road truck Diesel engine manufacture which is also used under the Mack brand name. International's brand of Diesels highly regarded before tier 3 emissions have largely disappeared without being able to provide a reliable post tier 2 emissions engine. Cummins has in development for release in 2024 an opposed piston 2-cycle Diesel for military vehicles using Achates Power licenses achatespower.com. The OP Diesel 2-cycle should do15% better on fuel economy than any other Diesel on the market with high power density and able to do much better on NOx emissions (down to 10%) of what is currently allowed in tier 4 Diesel emissions. Knowing that the OP Diesel engine is about to be released by Cummins may make Cat reluctant to enter the on-road Diesel market. The release of the Tesla Semi with a fully loaded 81,000 pound 500 mile range test on I-5 shown in the background may now make semi truck manufactures reluctant to put more investment into the limited production USA market of only 200,000 semi tractor sales a year. By 2024 the market demand maybe for a slightly longer range sleeper version of the Tesla Semi provided the $40,000 federal subsidy will apply. The slight of hand Elon Musk was hitting at the Tesla Semi release was the mega charging station for the Tesla semi will have a mega pack Tesla battery storage supporting them allowing solar power supply and the ability to bargain for off peak industrial prices for grid power. That discounted grid electric power cost then would allow Tesla to charge $0.07 kW/h. In California you probably can't get industrial off peak power that low. The cost of the Tesla mega packs probably needs to be sized a good bit above what a Tesla Semi will need due to efficiency losses. With a comfort margin something around 150% of the truck's its supporting. That would cost about as much as another Tesla semi for each Tesla semi it supports. I'd think a lot of the Tesla Semi's can behave very much like Tesla cars in that they sit over night to do a medium fast charge likely using 3-phase power. That should allow off peak grid power use at 100 kW/h per hour or about 2 times the maximum a typical modern house could draw at 200 amps or 48 kW/h per hour. That's still a lot of electrical power. If you've got 3-phase power to your home such as some farms might or your just lucky and its running on the poles you could likely have a Tesla Semi charge at home with a its own power feed and meter.

Cummins is nowhere near releasing the Achates OP engine for on-highway use. They got into a JV with Achates in 2019 to develop the engine for the US Army in armored vehicles. Any talk about the OP 2-stroke having lower NOx emissions than a 4-stroke is pure fantasy.

And, ultimately causing their engines to be unreliable due to lack of proper testing phase. On top of that, I would mention how the EPA fined Caterpillar for "infractions" that Caterpillar, Cummins, and Detroit Diesel were all guilty of, while also NOT fining Cummins or Detroit diesel for those infractions. This entire thing has been a plan for many years (whether anyone wants to believe it or not). And, if you are on any specific talks about EPA standards.... Please do not forget that, 1) the EPA has that new Kamalas Harris partnership for ALL class 8 trucks to be electric by 2027 - 2030, and 2) that current EPA regulations are deliberately strangling diesel engines for OTR. Fuel prices are also adding to this headache. Between fuel prices, EPA regulations and designs causing added failures on engines, and a host of other things I am unaware of.. The "system" is trying to make it too expensive to run fossil fuels as a way of boosting electric markets. However, when you get into electric markets, you have wonder about battery technology (which biden just used the emergency powers to boost resources for making them). You have battery weight to consider, life per charge of batteries to consider, and the fact that most likely, lithium ion will be the battery type. Have you seen what happens when you crack open a lithium nuke, I mean battery? They explode. The battery power necessary to run a class 8 truck for more than 10 hours at a time, turns those rigs into ticking bombs should a battery crack open. To comply with the epa/harris mandates of 2027 - 2031, you have to build X amount of vehicles (over a million), and on top of that, you have to build charging stations. It is, as of right now, impossible to meet this deadline. On top of this, making trucks in their current state of design electric, is criminal and unsafe. Doing so takes away one of the best safety devices on a class 8 rig : Jake brakes. There is no way an electric motor is going to allow for the same level of safety as a Jake. We are going to start seeing increased accidents from brake fade. However, I have spewwed enough commentary across more range than your video was intended to show. This is just my thoughts and such.

Give them like a 20 mile battery only range, maybe drive the steer axle in trucks with an AWD system through the hybrid system, and that formula could produce some very capable and efficient trucks. Full electrification is still more than 10 years away, and if we made them hybrids we could save a lot of fuel and make more torque with the same engines we already have on big trucks.

[@gerardorodruiguez5928]

At least they were already big time with heavy equipment so they could leave without much loss, many couldn't. But i found it funny and interesting how CAT reacted to the EPAs constant new bull crap standards because they weren't too worried about pulling out of the market like they didn't have to play nice like the others.

I remember those V8 Cat engine in Ford truck in Jamaica.

Can you make videos comparing trucks from different generations? Trying to buy a good cross country/car hauler that's reliable.

[@e3k701]

Like Ram/Ford/Chevy from the 90s, 00s, and 10s. 1500s, 2500s and diesels.

[@robwhite3241]

If you've got the dough id get a new gas truck like the ford 7.3. These new gas engines get the same mpg as the old diesels with the reliability and power. But if you just have to get a diesel (trust me I understand) cummins or 7.3 power stroke is the obvious answer, unless you're a GM fanboy.

What can you add regarding Caterpillar's 2010 acquisition of EMD? Was that a successful move?

[@wymple09]

I know the situation is not ideal with the EPA, but I'm old enough to remember big rigs pouring black smoke out the pipes as if they were burning dirty coal. A million trucks doing that to our air certainly wasn't ideal either. Tech waits for nobody. 2 decades on trucks are still rolling, still making money. If not, they wouldn't do it.

[@dmandman9]

EXACTLY! Nostalgia and rose colored glasses make us forget that. That black smoke looked nice. But it caused a lot of problems and wasn’t good to breathe. I work at a Ford dealership. If a 2008 or later truck comes inside the shop, I can allow the engine to run for a while without anyone noticing. But if I bring an older diesel or a truck with the emissions deleted inside the shop, I have to shut it off IMMEDIATELY, or the guys next to me will start cursing at me for trying to choke them out. I notice that a post 2008 diesel is likely to have a clean tailpipe. It isn’t even the characteristic black and soot coated as with older diesels. Yes, the EPA is a pain . But so is being choked by exhaust and black smoke, especially if caught behind or beside a pre emissions diesel in a traffic jam.

[@JohnCamp]

Ironically though, the older mechanically/hydraulically injected Diesel engines where far easier to convert to run on vegetable oil. But scary smog so make it a computer.

[@dmandman9]

And yes, other companies have adapted and are making money. As a side effect, engines are evidently even more powerful. In times past, I’d hate to get behind a truck even going up a modest grade because they’d almost slow to a crawl if hauling a load. Now they can maintain speed on modest grades.

[@453tye65e65e65e65]

The real reason trucks are still rolling is. There are more older engines still on the road (swamped into newer trucks) and lots of trucks have had their emissions deleted. Also, I hear that trucks over 800HP don't have to meat emissions

[@dmandman9]

@@453tye65e65e65e65 Some delete emissions. But most don’t. Reliability has increased. I admit that The weak point in the trucks we work on is still the Exhaust Temp sensor . That’s the component that can disable the truck . But they are a relatively inexpensive part and easy to replace. But in my experience since 2003, the trucks that give the most problems are those owned by urban cowboys who never Haul anything and drive their trucks around town on short trips. Those who use their f250-550’s as TRUCKS don’t have near the problems as the urban cowboy

[@bljuhl1345]

We’ve devolved, just by making a video to ‘explain it all’ Caterpillars used to be diesels, that means the engine can run without electricity, except for the electric starter, on off switch, headlights, it didn’t need electricity. We drove trucks in the daytime sometimes for hundreds of miles with just enough battery power to operate the turn signals and brake lights. Alternator failure didn’t stop us. Cost effective to drive to a repair shop or home

[@gurvanbolt9043]

I did used have 3176 but those could not manage the work so I changed the and used 3406C and have no problem
