Cummins spark plugs on Tucson Craigslist
#18
There was an engine that ran on diesel fuel, but was not compression ignition, it had spark plugs along with an injection pump. It had a lower compression ratio that a diesel would have had. Can't remember the name, but it was around in the 30's I think.

Yep spark plug on one side and injector on the other side. Just tried to fire one up that my dad had sitting for years and cracked the block made in the 50s I think So they are spark plugs on diesels.
