Wasn't it GM a couple of decades back that had the big fiasco of blown
engines when they tried to convert their existing gas engines to diesel?


Jim,

Yeah, GM's very first line of passenger car diesels were merely
converted small block Chevys. It didn't work so well. But, I would
hope that in the ensuing decades some new technologies have developed
which might make this a more feasable option.

AFAIK the only way to make a reliable diesel engine is to design it
to take the stress of a diesel from the start and gas engines aren't.

Maybe it's simply about preheating the fuel and retarding the spark.
People keep saying our engines are "just tractor engines."

Retarding the spark on a diesel?

The problem is gas engines go bang and diesel engines go BANG!!!.

This puts greater stress on the engine parts which isn't a problem
if you designed for that stress level in the first place.
