Question by jerry pace: Creating a new piston compression using magnetic pulses firing the engine ?
Old petrol engines use petrol to create an explosion in the bore to push the piston down but using a magnetic pulse instead of petrol to push a piston down to run a old petrol engine .New cylinder heads, pistons and bore liners can be inserted into a petrol engine to run it on magnetic compression but a long wind starter in needed to turn the engine at running speed to start it and a series of high voltage alternators to deliver electricity to run the electric pulses to create compression what is your opinion?

Engine casings are completely metallic. That said, the magnetic interference would cause the pistons to stick to the casing, and there would be little/no movement. Perhaps as a brand new engine using an insulating material instead of just replacing the heads and pistons would work for that part.
But then comes the question of the energy source. A petrol engine uses the thermodynamic properties of air along with the combustion of a fuel-air mixture to drive the compression/expansion cycles. Using magnetic repulsions *could* work, but honestly, why not just use a DC engine, and get more torque and efficiency out of the entire thing?
