[@Pickuptrucktalk]

There's been some questions about direct injection and carbon build-up on engines with this technology. I have asked about this with various engineers over the years and they have responded that the higher PSI of the spray nozzles, it atomizes the fuel better and removes this concerns. Here's an example of this explanation at the 3.28 mark of this video with a Chevy engineer. He is talking about the 6.6L gas engine, but this same information applies to most other gas engines. If you check out the spec charts online, you'll find the gas pressure spray PSI level for most is well above 2,000 with some being higher. The Hurricane engine has a "single high pressure pump providing up to 5,075 psi (350 bar) to a single fuel rail." kzbin.info/www/bejne/d5C5knl5pbZspLs

[@terrencejones9817]

Fuel pressure being higher makes zero difference. Most of the carbon build up happens on the back of the intake valves. A port fuel injector would spray fuel onto the back of the valve, cleaning it. A Direct injection engine can't do this ,because the injector is inside the combustion chamber. Now they can play with the variable valve timing a bit to mitigate some of this. But we had the heads off a 2022 6.2L gm last month. The carbon build up is clear. The only way to deal with it is frequent induction services, which currently GM does not require as part of regular maintenance. However, one of the first recommendations to diagnose a P0300 code ( random missfire) is to do an induction service with Top engine cleaner. The problem of carbon build up very much exists. GM seems to be fhe best at avoiding excessive build up. But it still happens.

[@Pickuptrucktalk]

@@terrencejones9817 The way it was explained to me is carbon buildup is left over fuel that wasn’t fully cooked. Higher spray causes better atomization and therefore you don’t have left over fuel. Thus, the carbon buildup on the back of the intake valves doesn’t exist. FYI - Ram has 5,075 PSI spray pressure.

[@terrencejones9817]

@Pickuptrucktalk Problem is that doesn't address what actually causes the carbon build-up on the back of the valves. It's not fuel, it's oil/fuel vapour from the PCV system. All engines burn crank case vapour through the PCV system. Higher fuel pressure will actually make this problem worse. That high fuel pressure dilutes the engine oil with fuel. That fuel in the oil causes higher pressure in the crank case. That fuel oil mixture is then sent through the PCV and its dumped right on the back of the valves. People that like to go on extended oil change intervals make this situation worse. The more fuel contaminated in your oil, the less it lubricates, the more the oil turns to vapour. Google the GM Dexos gen 3 spec. It's specifically designed to reduce oil coking/deposits in a turbo charger. The only way you get oil deposits inside a turbo, is if the shaft seal is leaking, or the oil is being pushed through the PCV system . My wife owns a 2018 equinox 1.5L turbo DI engine. I maintain it well. Recently in cold weather it developed a missfire. GM has a TSB about intercooler icing. When we pulled the intercooler boot off, it was full of water and oil sludge. The only way oil is getting into the intercooler is through the PCV system. I change the oil on this car every 3000 miles (5000km) I do an induction service every 25k miles to avoid the carbon build up. That being said, the discovery of oil in my intercooler, means I'll be doing another induction service soon. BTW, if you took a look inside the intercooler of any Ford Ecoboost, you'll discover the same issue.

[@Pickuptrucktalk]

@@terrencejones9817 all I know is the spray pressure is the answer I get from many different engineers at different companies. I’ll also add in the last few years I get confused looks from engineers when I ask them about carbon buildup. I take that look to mean they consider it resolved and have moved on.

[@tylerproctor4878]

​@terrencejones9817 I agree with you sort of. Better burnt fuel is gonna push back any meaningful carbon build up. How far it pushes it back? Who knows? 150k miles maybe. But yeah you are right. It's gonna happen and it makes it hard to look at these DI engines and not say it will eventually reduce the performance and longevity at some point.

As a mechanic I thought this was stupid idea. But in practice it works great and is sensible way to save fuel and put less wear on the engine. You can always disassemble it too.

[@markf8256]

Agree. From a practical standpoint most people couldn’t care less about the negligible emissions reduction. If it actually saved a noticeable amount of fuel (greater MPG) it wouldn’t receive such hate. As consumers we do pay a premium for this as the starters and 12v batteries are more complicated and much more expensive to replace. All of these changes to satisfy government regulations cost the consumer more. More up front and more if you like to hold on to your car or truck.

Oil is cheaper than an engine. First Generation 3.5 turbo charged Ford had problems with soot build up with the direct injection. The end result was the 7 ft timing chain they had in their stretched and the cam phasers quit working properly also. But for those that stuck with a 3-4,000 mi oil change interval they didn't experience those problems and get much more longevity out of their engines.

[@hellkitty1014]

Good stuff, Tim! To have the chief engineer explain some of the questions that everyone has about this new engine was so cool. I'm glad that you asked about the durability in relation to turbos. I'm not a Ford guy, but one thing they proved is that turbos engines in trucks do have durabulity and longevity, as witnessed by their Ecoboost V6s. That will likely be even more true for Hurricane due to its straight-6 design requiring fewer parts. It is concerning that yet, another automaker has 10K mile oil change intervals. So many automakers have gone to this standard and it is so aggravating. On a boosted engine, the oil is doing so many things to lubricate the engine. That causes oil breakdown due to many heat cycles. I don't care what any engineer says, ask any race engine builder and they'll tell you the truth. On top of that, investing $100 in an oil change w/ quality filter at 5K miles max is one of the best ways to ensure longevity. And WHYYY NO ENGINE OIL DIPSTICK?!?! Ugh... That Chrysler Turbine on Alan's back drop is still one of the coolest concepts that was never built.

How long (hours) does it take to replace the water pump AND is it easy or difficult to remove & replace it. 6. How long (hours) does it take to replace the alternator & is it easy or difficult to remove / replace 6A. Same question for the starter 6B. Same question for the battery 7. How can the owner physically check the engine oil level & transmission oil level. 8. Is the transmission oil cooler integrated inside the engine cooling radiator & if so is their a guarantee that engine coolant cannot mix with transmission oil due to breakdown of this arrangement 9. Since its direct injection, how frequently (in mileage) does the accumulated carbon have to be cleaned off of the intake valves or did you also add port fuel injectors in addition to the direct injectors to alleviate the problem altogether.

[@htschmerdtz4465]

Two sides of the coin: I had a 2.2L with a liquid cooled turbo in a 1984 Dodge Daytona and it worked well, no real reliability issues, all the way through 100k miles. There were some sensor issues and I did have to replace a cat, but overall, the powertrain in this car--which was a beater, a salvage car--ran pretty well, never burned oil, never broke anything internally until I sold it somewhere north of 160k miles. I did also replace the turbo, which didn't fail, it just got a little noisy, but the job was easy, so I did it to be safe. On the flip side, the air-cooled turbocharged Continental TSIO 360 in my airplane, not so great. These engines have turbos to maintain power, not boost it, so the engine will still put out plenty of horsepower as we climb higher or fly on hot days. They've changed little since the early 1960s and are not intercooled, still don't have EFI, ECMs or electronic ignition. We added an engine analyzer so I always know what is going on internally, but still, we have to baby this $60,000 engine so it doesn't grenade early and expensively. The engine has to have low-lead avgas, and like a dirty gray tsunami, the eco-woke are going city by city to ban the sale of this fuel.

Yes, it is in another video. Sorry. Premium fuel for top HP and torque numbers. You can use a lower grade and the engine will sense the lower grade fuel.

[@rondail5675]

I enjoy getting facts for the engineers!

[@tinshield]

Super interesting. Great interview.

[@joefriday6324]

I wish you would have asked him about the many Hurricane Engines that have seized up in Grand Wagoneer SUV's.

[@Pickuptrucktalk]

I hadn’t heard about that.

[@joefriday6324]

Yes....I was interested in one of the new Rams....but googled 'Hurricane Engine Issues' and there is discussion in forums about these engines in the Grand Wagoneer application. Always scary jumping into a new engine redesign the 1st year or 2. So, thinking about sticking with an F150....

[@carboydorifutoparty3976]

​@@joefriday6324what's the forums name exactly or where is it from? The most I've even heard of hurricane model wagoneers is either they have a ton of random electrical issues that randomly prop up,or the dealers don't tell people what gas to put in them which has the cars sensors going crazy because they put the wrong fuel in them.

[@brentmcmahon8188]

The inline six is a cool engine and I have had them in a GMC van and it was a 230 and 2 speed auto and them things would run for ever so excited to see this new motor and I hope the wild build this motor the right way with exhaust on one side of motor and intake on the other side and Iam sure that they will do it the right way and with turbos it almost has to be like that .

[@Zimbo999]

Thanks very informative and appreciated

[@charlespapineau5428]

I can appreciate Alan's comments on turbo engines from the 80s and 90s. Today's engines are designed with turbocharging in mind to try to mitigate the past reliability issues. However, turbos always bring more complication over a naturally aspirated engine. They are more mainstream because of the power expectations of customers and the CAFE targets of the government, plain and simple. Real world function over extended time will be the only real test for success. I'll be very interested in how a work Ram truck or a Grand Wagoneer that does a lot of towing will fare in ten years with this engine. I bet the electronics wig out before Alan's engine does.

[@TheCondoInRedondo]

I'm concerned about direct injection vs port injection with respect to the carbonizing of the valves and the valve seats. I have a 5.7 hemi with port injection. The valves remain clean. As for stop/start. My concern is NOT for the durability of the rotary portions of the starter or the brushes. It's for the clutch/pawl mechanism.

[@bfula9900]

Great video!

[@Michael-1337]

That engine sounds MEAN on that short dyno video!

[@rogeriopimenta6247]

What about the carbon build up on the valves?? They didn't adopt a dualport injection system, what have they done to avoid carbon from building up on the valves?

[@cs1992]

No dipsticks? 10k mile intervals? Start-Stop? I wouldn't hold my breath.

[@eddiegross4571]

Great interview , very informative interview with Allen thanks

[@raymondtennal1730]

Great interview...

[@SIMPLEHECHO]

Cylinder deactivation- Does this motor have it? If so, how does this play out in the overall engine’s long term durability? We all seen what the technology has done to the Hemi engines. The other manufacturers also have issues: cams and lifter failures.

[@680ecks]

Don't know why they couldn't build a non turbo version to replace the pentistar. Should still have the power of the old v6

[@shannonshull6989]

Very informative, excellent discussion. I'm more in touch with new tech and more confident in these new systems, tech, oil, etc.

[@eddiegross4571]

thanks very nice interview ,very informative

[@kensnyder2340]

Excellent video Tim. I'm not afraid of a turbo charged engine at all. But, I pay attention to my vehicles. My wife put 51,000 miles on her WRX, 2 liter turbo and not one issue with the engine. I do change oil often. I'm old school and it's not that expensive. I think Subaru has this turbo science down pretty well. They had some problems in the early years and overcame them. My wife was very observant as well. That car could pull 20 PSI of boost, but it could also climb any mountain in Colorado at 5 PSI or less. At 10,000 feet , 6 PSI is just atmosphere in the cylinder. It's hard to change people's perception though! 😎

[@paulhunter9613]

Turbo haters think that the engine is always under full boost, even at idle!😝

[@kensnyder2340]

@@paulhunter9613 , you know it seems that way. That would more likely describe a roots blower. They used to have that roll at idle, because they would build up a little boost at idle. The new style SC's don't do this. Refinement! With an adequate powered NA engine, a person can stay out of boost with a turbo. Most of these new engines though seem to need boost to be sufficiently powered, LOL.

[@paulhunter9613]

​@@kensnyder2340 while I don’t have a boost gauge to view, an eco can be driven normally without getting into the turbos I think. It appears that when staying below 2000 rpm between gear changes keeps it out of turbo mode, and that can be done with the 10 transmission it seems. But with city and suburban driving I usually get around 19-19.2, I can’t complain about that, my last truck driving the same way would not get much over 11 mpg

[@paulhunter9613]

What engines are using smaller turbos? Subaru?@@tellucas

[@synergytech7323]

I wonder during the testing of engines do they have a way to incorporate the heating and cooling intervals and the effect that causes. Thermal expansion and contraction rates that may fatigue components of a engine due to frequent cold starts. I usually get longer engine life when I let my engine rise to operating temps during idle. I see people start their cars then pedal to medal immediately. Is that a real concern for long term jeopardy of engine or I just being too cautious?

[@DirtE30]

Alan seems like a good dude… I’d love to have some beers with that guy. Engineers have a tough job… build an engine that isn’t the best get roasted. Build the engine that is the best, never hear their name. Lol I6 turbos are the GOAT

[@jonmeek3879]

Excellent interview

[@paulehlers2225]

Great listening to the man directly without talking head filters. It's not lost on me that the engineer behind this latest engine is using wallpaper of Chryslers most famous engine experiment of their Turbine engine cars.

[@alexgrindnshine2522]

The turbine engine is so cool. That design is what the US government used for the Abram tanks

[@Oldbuck73]

Great interview . I have bought 5 New Rams in my life . All hemi’s. Had to sell my Power wagon last year ,for reasons that better left alone . Hoping to get a new 1500 in a few months . Was half thinking of going to the Chevy 6.2 , but I really like my Rams . On the oil topic , I wonder why not use the 0-40 on the lower output Hurricanes , if it’s better for the HO ?

[@Pickuptrucktalk]

My understanding is you can, just not needed for the what the S/O engine requires.

[@Redfour5]

I like that you go to the source. I'm not sure why others don't ask the actual design engineers. I've loved my Hemi's, but the turbo element with the increased horsepower and torque IN THE MOUNTAINS is attractive.

[@jimerinrose6235]

Great interview. One thing I wished you asked him about how this engine deals with carbon build up since it’s direct injection.

[@jimsteinway695]

Wow they figured out a straight 6 will work. Toyota Land Cruiser and BMW have been using this motor normally aspirated and turbo charged for decades

[@garyhunchak1857]

I can tell you are young because you had no idea that the straight 6s were the base engines in the big 3 pickups once upon a time.

[@rustyredram7197]

If the high output oil is 0W40 for film strength / thickness due to increased pressures / bearing loads, would it not be better to use the same 0W40 oil in the non high output instead of 0W20? Also I get the joke about checking the oil but I think you don't give enough credit, I would argue many more people check the dip stick than you think. My truck gets checked at least every two weeks as well as looking for drips on the driveway where I park. That is how I found a rust hole in my diff cover and replaced it before it became an issue. I have had a couple sensor failures on engine over the years, not many, but never a dip stick failure. Sorry, I will get off my soap box now. Very good video thanks Tim and Alan.

[@Pickuptrucktalk]

What he is saying is OW40 isn't needed for the S/O engine since it doesn't have the same performance. If you use it, fine, but you are wasting your money. For the dipstick, the oil life monitor is more useful for the "majority" of customers and it will do a better job monitoring the oil than checking your dipstick since it not only checks the amount of oil, but the quality of oil. You can still check it yourself, the computer will just do a better job.

[@JHuffPhoto]

As he said, small displacement boosted engines can be reliable if they are designed from the ground up with boost in mind. I sure like my 5.7 HEMI in my RAM but I have also had ecoboost engines and they were reliable. I think maybe a boosted engine may be a little bit more sensitive to regular maintenance being done on time. I am certain that the new Hurricane I6 will be a success once the initial kinks are worked out. I give them 2-3 model years before I would buy one.

[@mikekratz39]

He mentioned crankcase contaminants being flushed out of the crankcase and burned. So now instead of the oil carrying them away and the oil being changed, the oil lasts longer but the contaminants end up on the valves and they need an expensive cleaning in the end costing a lot more money.

[@MrFescue]

Redirect your observation to the EPA and Politicians. There few options left to deal with combustion gasses in crankcase.

[@katlegokgethiliphoko]

I get that saving fuel is a very good thing, but it baffles me how Stellantis thought this is the 'right' engine for an SUV that weighs as heavy as 3077 kilogrammes (heavier than an Escalade ESV)😅 Maybe Jeep should've never pulled the plug on diesel engines.

[@kb9oak749]

I believe this engine is brilliant in design. However, I also believe things like plastic parts and other cost down engineering will render it an abomination.

[@alexgrindnshine2522]

Yes that’s my worry too. First thing I look at on new engine design is how much plastic did they use in the cooling system instead of metal. Plastic cooling system parts usually start to fail around the 3-5 year mark.

[@silvergeoff568]

Was hoping we’d learn about the power outputs when using regular unleaded. It’s my understanding that all the hp/tq numbers provided by Ram are when using premium. Is premium required? If not, what’s the hit on the performance? Can’t find those answers anywhere even though the engines have been in the Jeeps for a while now.

[@jonathanstansfield735]

Not a bad interview. Wish you would have touched on the hemi lifter issue if he has the inside scoop. Some things I would have brought up would have been the fuel octane and performance vs heat. I'm seeing 91 octane recommended and car and driver did a test with the new hurricane and it only got 20mpg vs a 5.7 hemi getting 19mpg. The difference of 1 MPG vs a minimum of $0.50-$1.00 per gal can easily mean the 5.7 could get better range for the money if you run it with 87 and use the same amount at fill up. Oil change 10k is no biggie as I run that in my Hemi but turbo engines run at richer A/F ratios which translates to more fuel in the oil so they should technically have a lower mileage oil change. I would have also asked about oil film strength on any stop/start as the bearing oil pressure drops to zero on stop, this puts more stress on the bearing as there is no oil pressure to create a cushion and all you have is film strength. Your biggest issues with turbos is oil seals and oil temperature. A water cooled turbo is always best like he stated but doesn't change the issues with turbos which is seal life. Would have been nice to know if they are ball bearing or journal turbos as both have there benefits. Forged pistons due to boost levels (20-26psi)? Are they running a colder spark plug? Are they incorporating a electronic wastegate and recirculating BOV system? Not a fan of a direct injection due to the high pressures, failure rate and expensive to fix but also a traditional injector also provides IAT cooling as the fuel is introduced early enough which benefits turbo engines big time.

[@stkrrauch1]

i have 4 vehicles and check my engine oil weekly /sensors fail which means so will this engine without a dipstick

[@gdessario5014]

Fill for life and transmissions is horse hockey. Cool interview though, thank you.

[@cliffweinan3907]

Thanks, nice interview of engine designer thoughts. There are many durability problems with needle bearing roller lifters, what have they improved? There is no check engine light with dipstick, it's between your ears !

[@grizz474]

For all the people that want to keep their trucks as long as they will last and believe that no added harm comes from running your oil to 10K miles....Good Luck. I also question not having duel fuel delivery. Ford learned that having only DI caused buildup on the intake valves to the point of affecting the way it performed, requiring to have them cleaned at a significant expense. I currently own a 2019 3.5 ecoboost with DI and Port injection with 81K miles. I have all the fluids changed when they're supposed to be and the oil every 5K along with tire rotation. So far it's been flawless....keeping my fingers crossed. 🤞

[@jslz74salazar18]

Great engine! Extremely abused and they keep on ticking! Fed LEs! Desert terrain!
