Back in the mid 1970's used to drive an old GMC single axle tractor from the 60's that was converted into a dump truck. It had a 6v53 Detroit with only a blower on it, The hood emblem had Toro Flow Diesel on it. I liked the way that engine screamed running it up through the gears(2100 to 2600 rpm ) It sounded real mean. Once the fine splines came off / wore off the blower drive shaft inside the sleeve the drive gear is on. The engine shut down. The blower was not pushing any air into the engine.
Count the exhaust runners on the exhaust manifold dingaling, it's a 6V-53T Detroit,
I've worked on Detroits since 14 years old...
now I'm 50 and considered the "Diesel Kahuna" of Waimea. I've handled mostly 6-71's,8V-71's,
& 12V-71 & 12V-71TT's...a 6V-anything is basically 1/2 a 12V. Don't speak too fast, you might have someone like Old Uncle Welda out there to have to shut you down, son...
The blower is there for induction, just so you noobs out there don't misunderstand. Without the roots blower, this engine cannot run. They do not produce vacuum on their own, a 2-stroke Detroit with just the supercharger is considered naturally aspirated.
@willDANCEforPENNIES Yes, it does. Like I said earlier, this engine does not create any vacuum to pull air into the cylinders. Without the blower turning, this engine could not run. These Detroit two-strokes which only have the blower on them are considered naturally aspirated.
@TestECull To correct you the engine could run without the blower if the turbos produced boost. Large B&W two strokes are inducted with a electrical blower at low load, but only feed by turbos once the turbos produce boost. But before the boost is there and at startups the electrical blowers are needed for induction.
Such a system on a small engine like this would probably be too complicate for the average user to maintain that it would not justify the saved fuel cost.
@StianM1979 Detroit 2-strokes have no vacuum. They can not pull air into the cylinders without the mechanical blower. As a result, if that's not there, they won't start, and if it fails, they run like absolute ass. They may even stall entirely if you throttle down to slow idle as the turbos won't be able to keep enough boost up, and of course the N/A ones will stall if the blower fails. You're welcome to turn that blower however you want but without that blower she won't run.
And no the detroits don't pull air into the cylinders. No engines do. They are charged by the outside pressure. You have supercharged engines and those that are charged by the atmospheric pressure. If you cared to check out the two stroke B&W and Sulzer engines you would see two strokes using turbos without a bloower.
Detroits are true 2 stroke, they are a uniflow 2 stroke, whereas the cerlist 2 stroke was a loop scavenged 2 stroke. The cerlist used no valves, where the detroit had either 2 or 4 exhaust valves in the head
Cerlist were made ini very very limited numbers, mainly saw duty in the military versions of the Jeep FC trucks, like the M877, stinky, noisy, not well liked
the last postinsgs are right, except for the Detroits being two strokes, they arent. The are uni-strokes, they intake through the valve and exhausted through scanger ports in the cylinder walls, were as two stroke both functions one valve
Air, under pressure from the blower, enters the cylinder through inlet port when the piston is at the bottom of the stroke and the exhaust valves open at the same time. Valves close and the piston rises closing off the intake ports and compresses the air. Fuel injected at or near TDC ignites pushing the piston down again. When the piston reaches the bottom, the process starts all over again.
The amount of power that a Detroit puts out is determined by the injector set-up as well as weather or not the Detroit is a High-Deck or a Lo-deck setup. Another factor is the induction set-up. weather it has blower, a blower and a turbo, or naturally aspirated is a major factor to its power output. Condition of engine as well as V or Inline are also factors
detroits are "blower scavenged" two strokes, meaning they must be equipped to operate. w/o a steady stream of fresh air to displace the exhaust when the intake port and exhaust valves open, the engine will (as another toober said once) "choke on its exhaust".
I've heard theory or tall tale about people who run a detroit 2-stroke w/ turbo only, but that was running steady at the rated speed in a stationary application.
6-53 means 6-cylinders of 53-cubic inches each. Thats only 318 total cubic inches! 300 HP from 318 cubic inches puts it in 'RACING ENGINE' class. These things at anywhere that horsepower were a very short-lived "HAND GRENADE"! Not too bad for a fire truck for short-fast hauls, or a boat with unlimited cooling and no lugging, but LOUSY in a long-distance truck.
i had my 6v92TA running 467 hp 890 lb ft with a biturbo setup and it lasted a year doing tractor pulls. now has more boost with over 1000 hp and has ran for 2 months without granading
If you want to see an engine like this one at work IN A TRUCK, watch "Goshen Boyer Engine." It's an International Cargostar tilt-cab fire truck with the same engine (minus turbocharger) and a stick with a 2-speed rear.
I rebuild these at work (MTU DDA) for the Aussie army and they pump 275hp no problems we've got plans to repower them to 300hp+ aswell. All you need are higher output injectors and a bit mroe boost.
I remember as a kid, this engine was popular in GMC and IHC commercial trucks as well as a few Brockway and White "Compact" tilt-cabs. It was also popular in Seagrave, American LaFrance, and Continental custom fire apparatus. I miss its distinctive scream.
that,s maby true when there brand new, but i had one in my ypr engine (4 jears old!)(new version of carrier m113 tank)ant it totally sucks!, problems with starting and breaking exaust valvés! (thus destroying turbo!)(nice sparks at night from exaust!)en a total lack of power!, ripping exaust manifolds, overheating,etc so... not that good!
Brings back memories of being out with our old '59 Seagrave K-cab pump when it was pumping. It was originally a 906 V-12 gas, repowered in 1983 with a 6V-53T like this one. I miss that truck.
these engines weren't trubocharged where back then unless it was an option because im seein a turbo on this one and alot of the old detroit 2 stroke engine videos i have watched most of them where not turbocharged
All two stroke diesels are are and were either supercharged or turbo charged. They can't run otherwise. The pressure is needed to force out the exhaust.
In most of the DDs, the turbo supplements the supercharger, which is needed to provide scavenging air for starting/low load running. In a few cases (such as the Detroit 6-71TIB marine variant, offered in 485 BHP form), there is a bypass valve in which the turbo air bypasses the supercharger (normally, it blows thru the supercharger), as it supplies more air than the supercharger can handle at high loads/speeds.
the silver series is used on the Canadian coyotes as well as the newest version of the APC the TLAV. by the way this one almost sounds like it has a miss in one of the injectors. i might be wrong but i does sound a little off.
This model engine was also common on the American M113 family of vehicles, and a turbocharged version on the long phased-out M551 Sheridan light tank. Terrible for noise discipline, one could hear a detroit-diesel-powered tracked vehicle from almost a mile away.
Actually they were quite common in the canadian military LAV's. I trained on them. They even had a jacobs, which gave it a nice 'aftertaste'after a max no-load run. :-)
Actually I've heard quite a few times people refering to the Detroit Diesel 8V-71 as the "318," for its horsepower rather than cubic inch displacement. It's confusing.
It's a Detroit Diesel 6V-53T; V-6 engine, 53 cubic inches per cylinder, turbocharged. This engine (albeit non-turbo) was common in GMC and IHC medium-duty commercial trucks, as well as Seagrave and American LaFrance fire apparatus during the 1970's. When I used to be a volunteer fireman, we had one of our Seagrave pumpers repowered with this engine. It has a lot of pep for its size.
Detroits rule, simple as that. For parts interchangeability, reliability and simplicity. With a few tickle ups they can also achieve quite reasonable fuel economy. The inline 6-71 is, if im not mistaken, the longest running production diesel ever built....say no more.
