Abstract

Considered modes engine load operations: 1 – test of the original engine; 2 – test with disconnection of four cylinders by stopping the fuel supply; 3 – test with disconnection of four cylinders with simultaneous cessation of fuel supply and absence of pumping losses of the cylinder-piston group (CPG) in the disconnected cylinders. The feasibility of using the method of disconnecting a part of the working cylinders of the engine, saving fuel at load modes of no more than 70% of the total and with a further increase in the effective power of the engine load, the time consumption of fuel becomes higher than in the variant without disconnection of the cylinders, has been proven.

Keywords
