a cummins b&c with spark plugs
I can almost hear half of you falling out of your chairs laughing at this but it is true...
cummins and westport are teamed to produce natural gas and propane engines

pick service intervals under any of the engines listed and you will see you must change the spark plugs every 24000 mi

Propane and Natural Gas have much lower energy content than gasoline. In order to regain some of the lost power for a given engine size, the easiest way to go is to raise the compression ratio since Propane is somewhere around 130 octane. The easiest way to get a high compression engine with good durability is to use a proven diesel engine and put spark plugs in it. It all makes a lot of sense when you think about it.

Cummins has been making LNG engines with spark plugs for years, I don't see anything unusual about it.
But who has seen the diesel engines that IH used to make with spark plugs?
They had a 1 quart gas tank and a compression release lever. You used the gas to get it started then switched over to diesel. Worked great.

Been there seen many of them, Farmall MD or Super MD or the ultra-rare Super MDV which was the high crop version if I remember right. Had gas engine stuff (spark plugs - distributor - carb) on one side and the diesel injection stuff on the other side of the engine. It was started on gas to get the engine temp up and then a lever was flipped which closed of a port inside the engine to jack up the compression so the diesel would fire if I remember right. It was a pulling engine as long as you could keep it running right.

My dad had a wd9 INT. with the same setup. Man it was a lugging old tractor. When you started it you could kick in diesel without shutting off gas, it would really smoke. The td18 dozer he had started the same way. Real tuff old motors!
