CONTROLLING CYLINDER USAGE DURING REDUCED LOAD ON AN INTERNAL COMBUSTION PROPULSION ENGINE
摘要
<p>While an engine is running with all engine cylinders being fueled, a historical record of engine output torque and engine speed is compiled. When the historical record discloses a change in engine operation from a relatively greater output torque and engine speed to a relatively lesser output torque and speed, fueling of at least one engine cylinder ceases while engine output torque and engine speed remain substantially unchanged at the relatively lesser output torque and speed by continuing fueling of other engine cylinders and by causing at least one mechanism to control the timing of operation of cylinder intake and exhaust valves of the at least one engine cylinder to substantially minimize pumping loss attributable to the at least one engine cylinder.</p>
