This is an interesting subject, never knew a diesel piston aircraft engine existed. Not to sound like a smartass but all the diesel engines in the sky were jet engines to my knowledge. From what I understand diesel is nothing more than jet-a with oil added for lubrication, more or less kerosene.
Hehe, last Summer I spent the majority of the time flying 172s in Ireland. Drove a Mitsubishi truck with a big ass tank in the back. Drove it into filling stations, topped it off with diesel (or red/green diesel if we could get hold of it), drove to the farmstrip, and pumped it straight into the 172.
Not a hiccup in 300 hrs worth of that.
