There are Diesel model airplane engines (or were) - they did not have a glow plug, just a thumb screw to adjust the volume of the combustion chamber. They ran on ether and caster oil. My primary memory of them is that they were very hard to start! I'm not sure that the glow plug engines are

The glow plug is a starting assist to raise the combustion temperature before start. It is not continous heat.. Combustion temperatures after start are enough to continue the run. Two stroke diesels ruled the world of diesels until recently [last 20 yrs].. I own 3 Detroit Diesels that are two

A diesel engine is a compression ignition engine with direct, timed fuel injection. Other compression engines are not diesels, including Lister Cycle engines that use kerosene or diesel with the fuel added to the air stream in a carburetor or which have untimed injection into the cylinder

Compression ignition is the principle of a Diesel engine. The fuel it runs on is immaterial. For example a compression ignition engine running on peanut oil is still a Diesel engine. In fact, that is precisely THE definitive diesel engine. So: Peanut oil, olive oil, soy oil, corn oil,

Actually, as I said before, the Diesel patents are for TIMED DIRECT INJECTION compression ignition with extended fueling duration (to get an adiabatic engine). Compression ignition is only part of the story, there were and are other compression ignition engines that are NOT Diesels. The
