Piston displacement is determined by the engine design. Volumetric efficiency determines how much the air-fuel can enter the cylinder at any given speed.Engine power is designed by the torque and the velocity of the engine. During power stroke, the pressure applied to the piston is determined by the amount of fuel mixture. Engine torque is decided by the pressure applied to the piston. These are the five factors influencing the engine performance. If the engine performance is good then, engine efficiency also at higher level.
