Efficient natural gas/diesel engine, ~97 MPG!

So basically it requires an ECM/PCM to control when or how fast the diesel is injected into the cylinders. I'm horrible on my diesel understanding but it has to do with the compression of the natural gas / diesel that causes combustion or ignition so to speak instead of a sparkplug that ignites the gasoline in the chamber. It has to be more efficient that electric cars no doubt and I bet cheaper too
