Definition of displacement
Exhaust volume refers to the ability to deliver all air and mixture to all cylinders during a certain cycle of the engine. It also refers to the volume that a piston can travel from one stroke to another. The gas discharged from the last stage of the compressor per unit time is converted, and the volume of the gas obtained under the pressure and temperature conditions of the first stage inlet state is the displacement of the compressor. It is calculated in the same way as the cylinder is calculated.
