Method of Engine Energy Indicators Estimating when the Cylinders are Disconnected in the Loaded Mode of Operation

Method of Engine Energy Indicators Estimating when the Cylinders are Disconnected in the Loaded Mode of Operation [Text] / A. Molodan, Ye. Dubinin, O. Polyanskyi [et all.] - Центральноукраїнський науковий вісник. Технічні науки. Вип. 7(38). Ч. 1. - 2023. - С. 159-166.

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.
