Generally in the auto and truck world comparing a diesel and gas engine of roughly the same size the diesel will generally get the better fuel mileage. Now I believe they say per a given amount of fuel the diesel fuel has more useable energy. So taking that into account I have wondered if any research or calculations have been done on the fact that a gas engine is more often than not working against the pull of vacuum created by its cylinders.

I believe in the case of a direct injection gas engine it still has to regulate the air entering the engine to maintain the proper air to fuel ratio for the engine to run optimally. Anyone have thoughts on this?

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power.
