I helped my dad install an exhaust brake on a 1984 8V92 in a dump truck. With the turbo uncorked it would shoot fire out the turbo outlet and actually lit his shirt on fire at one point. The two stroke detroits were the shit. Still love that two stroke sound. Sounds like they're turning 4 or 5 thousand RPM's.

[@kevinhornbuckle]

The compression ratio on the turbo'd engines are so high that a jake brake ends up doing most of the braking. That really saves the brake shoes and drums.

[@JoeL-kn9tc]

The teacher really knows diesel engines and their history. I worked in Detroit in the late 60's and early 70's and Mobil would fill our fuel tanks. They used a Dodge COE with an 8V-71 318 (sounded more like 350) engine. They had thick twin exhaust stacks flared to the sides pulling a double tanker (lead tanker and pup) On quiet, humid summer nights you could hear himcoming a mile away. The deep and loud roar of the 2 cycle was music to my ears. Still is.

[@nmdiesel89]

The design of the Detroit 2 strokes was genius after all Charles Kettering had a hand in them. most parts were interchangeable between series. Want a bigger engine? Just add cylinders to an already proven platform. Drove a wrecker in Iraq, had a 8V92 rated 450hp, grossed 120,000+ lbs pretty often and kept up with mraps with cummins (my 2nd favorite) rated at 400hp weighting half as much. She would spin 25-2800 all day and kept asking for more. EDM still uses alot of the Detroits tech even today.

@@Romans--bo7br you could say that, unless you consider that both emd and detroit were gm divisions. Charles Kettering ran the GM research division that conducted research on behalf of both detroit and emd/emc. E. W. Kettering developed the 6-71 detroit and the emd 567 during the same period, then went on to be the chief engineer and eventually division head of emd. So ya, the two divisions had nothing to do with one another besides the engineers designing the engines. The engineers went from division to division just like the rest of GM's divisions, the 2 are linked through their development in the late 30's and after.

Direct injection on gas engines was used in 1912.... manufacturers only recycle old technology.

[@ct1762]

sort of. the principal is still the same, but the tech has come a LONG was since then. now we have ways to atomize the fuel, creating a more complete fuel burn.add that to a computer that sense engine parameters, and weve come a long way. we now have 2 stroke outboards (dating back to 1996) that are cleaner than 4 strokes

[@chaytonruijsenaars3971]

no kidding eh, ww2 most american tanks had reliable mechanically fuel injected engines and automatic transmissions like the stuart and Sherman (if I'm not mistaken) and cars didn't start to use fuel injection till like the 80s and even then it was a nightmare

[@ct1762]

Righteo ! But of course all this tech comes at a price: reliability. The actual rotating assemblies of modern engines are usually very reliable, but that doesn't really matter when electronic bits can't keep up. All sorts of problems with new motors on many types.

[@jlo13800]

You can say that again!

[@PistonAvatarGuy]

Most American tanks in WW2 were carbureted, only the diesel powered tanks had fuel injection. Gasoline direct injection was widely used by the Germans on their aircraft engines during WW2. Honda had an awesome fuel injection system in the '80s, I was driving cars with their first fuel injection system well into the 2000s without issue. The Bosch EFI systems that NIppon-Denso built under licence were also pretty good, but not as good as the speed/density system that Honda had developed. And I don't know what you guys are driving that have problems with the electronic components in the fuel injection system, but the only things I've ever had to replace were O2 sensors, and those are just maintenance items.

A very educational video for me. This instructor has constant enthusiasm. I wish some members of the audience would kindly keep quiet while the instructor is trying to explain particulars about this engine. Anyway little did I realize that common rail has been around for this long. About spraying oil around the pistons, Case tractors had this in their engines in the mid Seventies. The people who run CARB are a bunch of university educated yuppies who really are a very,very boring bunch of people. Luckily for me I use to hear Detroit Diesel power on transport trucks crossing the Ambassador Bridge in the early Seventies while attending university in Windsor, Ontario, Canada. Lets hope somebody will always manufacture parts for all old Detroits. Lots of Detroit Diesel fans out there.

Still can't get to grips with these things being called antiques, they must get into your blood after 20 of so years. One thing the instructor could have done to really impress the students would have been a slow idle, with a heavy flywheel an 8V71 will idle down under 200 RPM, not good for extended time but impressive all the same. You can almost hear each cylinder fire. Love the instructors energy, very infectious should be more like him.

Bob Homer hehe I wouldn’t say couldn’t. Those old Detroit’s had a nasty habit of sometimes getting stuck on full fuel either when the rack got stuck, or the rack pin in the governor would break or fall out (usually that only happened after an overhaul, which is why we always had the CO2 fire extinguisher ready when we would do a first start on one in the shop) Luckily I worked in a place where the old timers knew these engines, I’m the only one my age that I know of who knows how to set a Detroit rack and governor.

I miss the old 318 Detroit, with a 13 speed road ranger, I love it it wound up

[@victordjinn632]

318 had a 250 rpm power band from 1900-2150 governed against over rev. Scream it, grab a gear. Scream it, grab a gear. 13 speed, Low: first, second, third, fourth, split 5 direct, split 5 overdrive, 6 direct, 6 overdrive, 7 direct, 7 overdrive, 8 direct, 8 overdrive. Screamin' Jimmy! Yeah, they were sweet. I also drove a 1976 FORD 9000 Louisville with a 6-71 DETROIT, inline six with the same transmission. Governor was set for 2300. Instead of exhausting through twin stacks there was only one. This baby would wake the dead. I can remember many times going through small towns at two and three in the morning. I could see the bedroom lights coming on in the side mirrors as I rowed the gears down the street. A lot of drivers didn't like the Road Ranger. They preferred the Fuller, which was Low, Intermediate and Direct; instead of Low, Direct and Overdrive. One transmission split the gear; the other split the range. To each their own. I liked the Road Ranger myself, but, I was equally proficient either way. It's difficult for anyone from that time period that was hands-on, to not have a certain sentimentality for the Detroit Diesel.

[@Romans--bo7br]

Victor Djinn..... Fuller and "Road Ranger" was ONE and The Same!!.... "Road Ranger" was the series brand name of Fuller Transmissions!! As far as the 8V71's "power band", it was NOT from "1900 - 2150"!... its actual power band (maximum Torque curve) was flat, from 1250 to approximately 1750 on the factory, temp controlled dynamometer readings... however, "real world" power output is wholly dependent on timing setting, injector size, elevation, ambient outside temps, barometric pressure, humidity, etc, etc.... just like Any engine... the outside variables Always dictate the actual power output at any given time.... and as far as actual power available at the wheels, where the numbers really count.... add to all the above, the final overall gear ratio between the transmission(s) and the differential(s) as well as rim/tire size. Also, and Very importantly.... the lugging ability (sustainability) of the torque produced by ANY engine, is Directly related to piston Stroke travel and whatever overall gearing between the flywheel and the tires..... gearing choices and "make or break" the power output of ANY engine. I won't question whether or not you actually ever drove a truck.... but from your description of things, I will say that at the very least... your "information", or the source of it, is seriously misgiven.

[@victordjinn632]

EATON. FULLER. Two separate entities. EATON acquired FULLER in 1958. In 1978, the 13 speed EATON ROAD RANGER transmission split LOW, DIRECT and OVERDRIVE. The 13 speed FULLER split LOW, INTERMEDIATE and DIRECT. This was how we (Halliburton Cement and Acid International) distinguished between the two. They are different. Not the same. Our 6-71 engines were governed for 1900 to 2300 rpm. Our 8-71’s were governed for 1900-2150. When the engines were in service they were not operated below 1900 rpm. Below 1900 rpm the truck was stationary at an idle. The engines were not lugged. When rpm dropped down to 1900, the transmission was down shifted, and the engine revved back into the power-band. As a matter of fact, if a driver was caught lugging an engine it was grounds for dismissal. The same thing went for the dummies that think they’re showing the world something by shifting without the clutch. As you can see my post is not written in the interrogative, and, there will be no further discussion. CLASS DISMISSED!

I live in the part of Pennsylvania where strip mining was a big thing. In the 70s, my friends dad was the operator of a Euclid TC-12 bulldozer. That was a huge machine that had an engine and drivetrain for the right side and a separate engine and drivetrain for the left side. Both engines were Detroit 6 cylinder two strokes. Because of the high revs and distinctive sound, the machine was referred to as the, “buzzin dozen”. I watched it work. It had a blade that was really wide and really high. When he was stripping cover, the blade would gather a pile of dirt to where he couldn’t see where he was going and the machine rolled on like it was running empty.

Great teacher! Great engine! Great sound 🤘

[@2009dudeman]

An amazing beauty of an engine. I just love old diesels. Nothing makes me more irritated that some liberal hippies crying about the planet kill these engines.

[@douglasmontilva1800]

What a beauty of engine, very advanced with its four valves per cylinder and also very little smoke, wonderful engine! the engineer who presents it very accurately in his comments, thanks

[@concrete2733]

love the sound of it

[@madhut3042]

I love this engine I love the enthusiasm

[@bobsmith2637]

Detroits are impressive, but if you want to hear some real power look up the EMD 567, EMD 645 or EMD 710. Those numbers are cubic inches per CYLINDER! They are mainly used in locomotives, ships, and stationary generators. The largest version (V20-710) produces 5500 HP. Electro-Motive is Detroit Diesel's much bigger brother.

[@mikemoore9757]

That is one rowdy engine. Can you imagine starting your car at 6:00 am with that thing under the hood , and in a quiet neighborhood!

[@ty2148]

Actually it does have valves. The intake air is forced through holes in the cylinder sleeve by a supercharger. The exhaust is released by camshaft driven exhaust valves in the cylinder head.

[@leneanderthalien]

Yep, all diesel use on big ships are such type of 2 stroke diesel, but the fuel injection is pneumatic because they use heawy fuel (improve spraying)

[@cidertom5140]

leneanderthalien you are wrong not all ships have twostroke engines cruseliners tend to have big engines of up to 1000L and are fourstroke engines with anywhere between 9-20 cyls and only rev up to 500rpm

[@leneanderthalien]

cidertom Small ships yes, but the luxury cruisers like the Queen Mary 2 use electric drive, so they medium speed engines are electric generators, not direct drive engines because at 500rpm they need a reductor to drive a marine propeller... The biggest ship engine of the world is the Wätzilla Sulzer 14 cyl RTA96C, two stroke 108 920 hp direct drive at only 102 RPM...

[@tomcat8316]

@Dingus E. Dow I bet these guy's would have fun with ww2 sub engines (us ) 9 cyls. 18 pistons

[@OtisENGINEuity]

I want one to play with and piss my neighbors off with!

[@crazydiesellover]

I would love to hang around this guy! Reminds me of my diesel technology teacher who taught me many things

[@roybm3124]

Very nice video, lovely sound!

[@matty2helpfull]

Thats a mighty fine running old 318 Detroit

[@tomcollins494]

Music to my ears. Old greyhound buses from the sixties. Unmistakable.

[@BoopShooBee]

tom --- Rode on those buses when I was in the service back then. They were quieter and more comfortable and a greyhound bus drivers wore uniforms drove fast and were respected.

[@MarcABrown-tt1fp]

@onetimehard ltd. Most of those old buses have lost their sound damping materials through the rot of time they could be easily quiet.

[@StarFox1988]

you know what? this guy is pretty dope to listen just explain the motor, VERY enthusiastic about it

[@bigbuckslayer11]

+dennismins he says four exhaust valves with intake holes in the cyclinder and the piston acts as a slide port

[@southernwaytransport]

Very informative video. Wish youd explained the hp ratings on diesels vs gas, Ive been around trucks for 40 years, and none of my buddies seem to understand the reason big semi engines are only rated at 350-450-550 hp. I try to explain its the constant output within operating rpms, plus the torque that really matters. Those detroits werent much, maybe 850-1250 ft lbs, modern engines range @1600-2200 ft lbs..while getting the same (if not better) fuel economy.

[@robertomedina9061]

The Detroit is a starter motor, regulating well the zippers and using the caliber to calibrate injectors, starts with the gas oil of the injectors.

[@leepinlepin]

Those old Detroit's are loud and love to run at high RPM, and have brute force in torque. I love em!

[@clintonleague1272]

It sounds like you need a tune-up. Injectors set at 1.484, valves set at 16 no go 14 go, run the rack with the throttle wide open number one on both heads adjusted to maximum travel the rest of the injectors set the same with a 1.500 gap set on the air gap in the governor, then you will have run the rack and after starting you adjust the buffer to remove that pitiful lope you have at idle. Brings back old memories of the good old days! Drove a million miles on top of a Detroit Diesel and remember every mile! Just saying, thanks for a refresher on the memories.
