Fuel injection of petrol (gasoline) engines followed on from the development of this technology for diesels. Diesel engines came into widespread use for ships, railway locomotives, buses and trucks in the 1930s, and I'm aware that the Germans used diesels for aircraft engines in WW2. Application for aviation petrol engines seemed to follow on some years later (for Wright at least, it seems), and for car engines later still.
A question for 411A and others whose experience is way beyond most of us here, did you have the same issues with carburettor icing and similar which afflict light aircraft engines, and how were such issues overcome on reciprocating larger aircraft ?
