Tesla invented the coil. The ignition of gas, and later, gasoline,
engines was the obvious application. Before tesla there were huge
stationary engines used for pumping water. They had used a pilot
light, exposed to the combustable mixture with valve gear. Not for
high revs to say the least. With a plug instead of a flame port, it
was possible to compress the mixture before lighting it.

Why not a diesel cycle for gas engines?

Harry should know why, he's tried to tell people here that he's got a
degree in mechanical engineering!!!!!!!!!
