Compression Stroke Stage  1
Stage 1 of the Compression Stroke: · AB Engine piston reaches the V2 position, producing the same magnitude of work, W_{X1}, as at stage 3 (Intake Stroke), but of opposite sign. This means that the net work produced by the AB Engine from point 2 to 3 and back to 2 on PV diagram is Zero. It is a well know effect of an adiabatic process called “reversibility.” · Temperature and Pressure in AB Engine Combustion chamber are the same as initial T_{1} = T_{atm} and P_{1} = P_{atm}. · Conventional engine is compressing gas at this point · In part, the purpose of calculating V_{2} is to satisfy the equation:
The conditions of this equation set a similar gas compression ratio (for the same gasfuel mixture) in the AB Engine as in the conventional engine by the end of compression stroke.
