Cylinder Cutoff of 4-Stroke Cycle Engines at Part-Load and Idle 820156

In order to improve fuel consumption, the effects of cylinder cutoff on engine performance were investigated on a 4-stroke cycle in-line 6-cy linder gasoline engine.
It was found that the cylinder cutoff obtained by deactivating both the inlet and exhaust valves was very effective for reducing the fuel consumption at part-load and idle, as both the pumping power for the inlet and the power for activating the inlet and exhaust valves were noticeable decreased.
