I am not sure how many of ya'll remember the 8V 92's and how well they ran if you where pissed off and beat the tar out of it. When I first was tought to drive they always said open the cab door slam your fingers in door then drive the detriot! Now with that said why is it that no company has tried to us the 2 cycle diesel in smaller trucks. I know that the detriot was an oil leaker and all the bad points but you shure couldn't beat the way she would run up. Just a thought.

 

You must have either forgot how loud those detroits are or you have no hearing left to worry about. Once you've driven a detroit you've heard enough.

Just my 2 cents worth.

8V-92, by definiton:Eight cylinder, Vee configuration, 92 c.i.d. PER Cylinder!
Converter-the only diesel engine that could effectivly convert diesel fuel to pure noise!

Yeah, but they had their place in history. They were extremely non-efficient, and dirty engines. Two-cycle detroits are where the racers got their roots-type blower technology from. But they had nasty issues. The air boxes would fill with oil, and then the engine could "run-away", burning it's own oil with little or no way to stop it. You could still get them in a "non-highway" application up until 1996. They had DDEC controls on them. Fire departments loved them because they could be started cold(Moderately cold since they are kept indoors) But they could essentially "pour the coals" to them and not have to worry about the performance characteristics of a cold 4-cycle diesel.

 

Trust me I know all the bad about them but they would run when they where set up corectly (if you had the know how to do it). But with todays know how and the 2 cycle spin up I think a good motor could be made.

 

The 8v92 is definatly a screamer and has enough horsepower but just not enough torque compared to a 400BCII Cummins or a 3406 Cat but the 92 could match the horsepower. There are a quite a few dump trucks and sewer pumper trucks powered with these engines and you can hear them comming for miles down the road. I worked with two excavtion contractors that have a Interational 5000 thats 8v92 powered and the other contractor has a 2675 International thats 6v92 powered and both screaming noisey trucks not pleasant to drive. The truck thats powered with the 6v92 the truck is way underpowered and the truck with the 8v92 isn't too bad but once you have lost the rpms of the engine (Lugging) the truck is a dog also.

The 2 strokes work good in marine applications and thats it truck applications were not so good. Another reason why the Detroit engine was used is they are cheap to buy and cheap to maintain heck they change their own oil by themselves.

One of the reasons why busses and fire trucks used to use detroit 2 strokes are they fairly compact and fit into tighter engine bays where a big Cat or a Cummins won't. Then most of the time these Firetrucks are equiped with Allison automatics so when a firemen drives the truck they can just mash the pedal to the floor and the detroit would just scream and the power would be consistant.

Anyhow I wouldn't want a Detroit powered truck they are not economical enough.

 

This is just my opinion: A 2 cycle engine is (usually) smaller, lighter, more compact and above all less expensive to build. A 4 cycle engine will weigh 40% more than a 2 cycle. Who would want a 4 cycle on a weed whacker? Having said that, the Detroit 2 cycle diesels have few (if any) of the above attributes. 2 cycle: no cam, valves or valve actuating hardware. The Detroit has all of that -- no savings there. Additionally, the Detroit won't run without the supercharger (very expensive to manufacture). Not to mention that the detroit was the dirtiest (from an exhaust emission stand point) diesel engine ever produced. Since "we all breath the same air" I am personally glad to know it is history!

 

>Who would want a 4 cycle on a weed whacker?

Oh!......If you only knew.......................

Joe, can you build a PowerStroke for my sears weed-whacker?
Holy-cow! Can you imagine that if it was chipped?!?!

Dang ol' weeds........

 

I miss the sound of that detroit running. The log shovel that I used to run had a 6v53 that used to scream in my ear all day. I was young and thought that ear plugs were for the weak so I would crank up my walkman so that I could hear the music over it screaming. Now I can't hear my wife bitching at me But I still think that they were one of the coolest sounding engines ever.

 

yeah the old 2cycel was bad in some points but like they say they sure sound cool the detroit can also be run on and converted to run on almost any fuel .the thing we need to remember is with out them we would not have our powerstrokes the came up with unit type injectors what a god send ,the psd also has similar injectors .I for one would love to see detoit come out with series 30 or 40 for the pickup line just a scalled down version of the series 60 those engines are some real power houses.a four stroke yes but still more power.

I was a volunteer fireman in a combination paid-volunteer department about 8 years ago and since I was single at the time the paid guys encouraged us volunteers to sleep over in spare bunks so they would have a full crew if they got a night call. The first out truck was an American LaFrance pumper, the century series that had the open style jump seats on each side of the motor. Man, I am telling you there is nothing like waking from a dead sleep and sitting smack next to a 8v92 in an open canopy along with air horns and a Federal mechanical siren screaming. I probably lost a bit of hearing but I wouldn't trade those memories for gold.

 

Yeah I for one would love to have one of those in a '72 Ford or a new pickup truck. In the town I live by your the #####'s if ya have a Dodge with a Cummins. I would be way over and above the others if I had one of them in like a '72 Ford.. I love my town, where if ya have a loud diesel pickup truck you can get all the hot chicks ya want!! I was told that Detroit still made two models for the armed forces.. And I think that two-strokes are outlawed in California and Canada. Soon to be the rest of the U.S. too. I guess all good things must come to an end sometime.

 

The ones that I remember were the 8V71s, the 318s. They, and the 6V71s were the loud engines, just superchargers with no exhaust turbos. Hell of a water well engine but not worth a darn in a truck. All I can say about them is they were tough. Detroit finally made a good engine with the 60 series.
