Analysis of the Influence of Gas Cavity Volumes in a Piston Hybrid Power Machine with Two Suction Valves

The influence of the increasing spaces of a piston hybrid positive displacement power machine with two suction valves on its operating integral characteristics is analyzed. It is found that with an increase in the volumes of the suction cavities, the flow rate of the liquid in the cooling jacket shifts towards an increase in the crankshaft rotation angle, the average flow rate of the coolant and the delivery coefficient decrease significantly, while the indicated isothermal coefficient of efficiency decreases insignificantly.
