Multi fuel?

Go over to SS linked above for weeks of reading about the multies. Basically, the MAN corporation in Germany developed this design for use on freighters. Continental licensed it for small engine use in the US. MAN called it the Hypercylcle and Continental called it the Whisper Engine.

Because the shape of the combustion chamber (piston) is so different, it allows fast and slow combusting fuels to be compression ignited. The military loved it because everybody thought WWIII was going to be fought when the USSR came through the Fulda Gap. They wanted NATO forces to be able to use any fuel station, home heating oil tank, grease pit they could find as a fuel source during what was envisioned as a fast moving fight.

Continental, White and Hercules all built the engines over the production run of the trucks. The EPA basically outlawed the engines in the 1986 for new truck production. More of "Whe're from the government, we are here to help you" stuff.
 
interesting, i run diesel, biodiesel, and have run kerosene in my M1009, but refuse to run WMO because im a treehugger. I do know guys that do it though. Pretty much the old mechanical injected diesels were mulitfuel engines as far as i knew. I also know of individuals who run their VW TDI jettas and rabbits as mulit fuel engines, running WMO and biodiesel, and the like. really the only thing that kinda confuses me is running gasoline in the mix. wont be trying that in either of my diesels anytime soon.
 
i run my deuce on 50/50 motor oil diesel... my granpa had a bunch of 50 gallon drums full wmo.. so id filter and just add to the tank... speaking of deuces.. i cant wait to go back home to pa and drive mine

Your M1009 is NOT a multi fuel!!!!!!

You will cause damage with gasoline for sure!
 
Don't use gasoline in the 6.2. There is an excellent 42 page pdf copy of a government report about bad things that happen to the IP on the 6.2 when gasoline is used. It is over on SS if you want to see it. The Pump drive shaft freezes up and either snaps or causes the drive gears to lock up and strip.

Limited amounts of WMO, WVO or ATF have not caused people damage. However, just about everybody I have read about that runs these. Has a spare pump on the shelf ready to go on the truck in case they ruin the one on the truck.

Use with caution.
 
no no guys, i would never run gasoline in my diesels, either one. the M1009 does have hardened internal parts in the IP. But thats why i feel ok running diesel, biodiesel, and kerosene. but thats it. never any gasoline, never any WMO, never any WVO, never any ATF. I happen to like my vehicles in running condition.

again, tree hugging hippy here. I drive diesel vehicles so i can run biodiesel, because its carbon neutral, and has better burn characteristics, if slightly lower in energy per gallon. gasoline has no such benifits.
 
I saw at least two of those gigantic straight six continental multi-fuel engines lying on the ground at a local junkyard..both looked new.had tags stating they were rebuilt in 1986,had the rod & main journal sizes stamped into the tag..They cut up several deuce and a halfs a few years ago they bought at auction,I saw a dump bed just like the one pictured here lying not far from the engines..I felt it was a shame the engines were left out to the weather lying on the ground!..:(

Where do you get biodiesel? Do stations out there have it at the pump?
 
Hypothetically speaking, what kind of trouble is one look into when installing one of these multifuel behemoths into a GM4x4, fedzilla EPA specifically?
 
Um, they weigh 2000 pounds, red line at 2600 rpm, have an SAE#3 bellhousing pattern and produce about 130 hp.

I have a spare multi on the floor of my shop. A 2 ton engine hoist can't pick it up. They are heavy, big and not really all that powerful.

Cummins 6BT would be my suggestion if you have the desire for a big straight 6.
 
I knew they were heavy but:eek1::eek1:!

Yep, knew about the Cummins too, been on the prowl for one for a little while now.

I was just asking because I'd never heard of it. Now I know why...:doah:
 
Conversely, a Cummins (or Duramax) would be a sweet engine to swap into a Duece, but you would loose multi-fuel capability and some of the cool old-school military vibe.

there is a station by the pentagon that is open to the public. cant buy anything inside the store though, just fuels. E85, CNG, B20 Biodiesel.

Captains K citgo. just off army navy drive.

as to swapping in an old school detroit diesel, 4-53Ts are a sick swap, although i have no idea if they were ever made as a multi fuel. although if the multifuel engines were 53 series, and the piston is the major component that differs, it stands to reason that a multi fuel 4-53T could be made.
 
Continental, White and Hercules all made the same engine (LDT-427, LDT-465, LDS-465) under license. DD never made a multifuel. At least not beyond what end users pour in the tank and hope works.
 
1948-1956 M35 had a REO "Gold Comet" OA331 Gas engine.

1956-1962 M35A1 Continental LD-427 multi fuel normal aspiration.

1962-1988 M35A2 Continental LDT-465 turbo charged multi fuel

1988-19?? M35A3 Some kind of CAT V8 with an Allison automatic. They cut up 3 M35A2 trucks to make 1 M35A3. I do not know how long the A3 program went on. I just know it didn't last very long and the trucks have a bad reputation among people that mess with MV's. Tempermental engine, failing transmission, ATIS that lets all the tires go flat and stay flat, etc... Others love them.

There were also several dozen or more M35A2 trucks fitted with 12 valve 5.9 6BT engines. There is still a place in NC that sells the kits to bolt in a 6BT.

I do not know of any program or kit for any DD in a M35. Lots of MV's did have different versions of the Detroits, but not the M35 series as far as I know.

Do you have any more info on these? I have a buddy at work claiming B.S... Says there is no such thing as a v8 deuce and a half.
