Abstract: An ECU controls waste heat quantity of an engine according to a required heat quantity in response to a heat-utilize requirement. The ECU controls a valve opening period of an intake valve based on an engine driving condition and an ignition timing based on a most efficient timing at which fuel economy is highest. The ECU determines whether there is an ignition advance margin relative to the most efficient timing. When there is no margin, an actual compression ration of the engine is decreased by advancing or retarding a valve close timing of the intake valve and the ignition timing is advanced relative to the most efficient timing in order to increase the waste heat quantity.

Abstract: Systems are disclosed that enable an internal combustion engine to dynamically alter piston displacement. The alteration is dynamic, because it occurs during engine operation, rather than requiring stopping and disassembling the engine. It is piston displacement that is altered, rather than engine displacement, because the actual volume that is displaced by a piston (as it moves within a cylinder) is altered. This is contrasted with the prior art practice of starving some cylinders of fuel. Because “engine displacement” is conveniently defined in prior art multi-displacement systems, to include only cylinders that actively produce power, the fuel-starved cylinders are excluded from a calculation of “engine displacement” and thus the “engine displacement” allegedly changes. The disclosed dynamic alteration of piston displacement is the alteration of actual displaced cylinder volume, and is differentiated from alteration of engine displacement.
