Thats one of their natural gas engines. Same thing as thier as the diesel engine but uses spark plugs. You can get the natural gas engines in a lot of the same displacements as the diesel engines.

International did back in the 50's! They had a diesel that had a carb. on it and spark plugs with a compression release lever. You would start it on diesel and when it got warm you pushed the gas lever down and pulled the diesel lever on to raise the compression and run the injection pump. They started pretty good, I think on diesel they were like 14.5 to 1. You asked!

I'm going to have to get technical here and say that you found a Cummins engine with spark plugs, but you didn't find a diesel engine with spark plugs.

when I worked at Cat they would get gen sets in, old 12 cylinder monsters that had spark plugs, also run off natural gas. Things sitting on the ground were taller than a man and as long as a honda. Not a diesel though, natural gas....

Farmall Super M diesels had carbs and plugs.

Almost all Cooper-Bessemer 4-cycle power engines could be supplied as spark gas, dual fuel (pilot diesel igniting natural gas) or straight diesel engines. One could even purchase an engine that would operate in all 3 configurations and would switch between dual fuel and straight diesel on the fly.

There was an engine in the 30's (i think) made by either wakashau or buda that had a lower compression ratio than a diesel, but higher than a gas engine, not high enough to compression ignite. Had an injection system similar to a diesel, but it had a spark system that ignited the fuel. Ran on diesel and current electric starting systems of the time could handle starting it. If memory serves me right it was used on Allis Chalmers(maybe Monarch at the time) crawlers during that time period.

The farmall gas/diesel combo was their solution to difficult starting at that time. Other makers used small gasoline engines to start the diesel. Farmall used a unique approach. Very complicated head design with an additional chamber for gas ignition and to lower the compression ratio so that electric starter could start it. Not to mention the addition of another manifold strictly for starting, magneto, etc.

The military also used multi fuel engines in several models of the 2 1/2 and 5 ton trucks. Just lost the last one in my old unit a few years ago.
