ENGINE CONTROL SYSTEM Russian patent published in 2017 - IPC F02D23/02 F02D41/04 F02D41/38 

FIELD: engines and pumps.

SUBSTANCE: control device for a motor which uses a parameter of gravity center positioning of heat generation rate determined by the heat generation rate as the heat amount per turn unit of angle of crank-shaft generated by fuel combustion, depending on the engine operating conditions and the vehicle in which engine is installed. In particular, the increase in the turbocharging pressure is performed when the engine and vehicle speeds are lower than the predetermined reference values in the case where heat generation rate center-of-gravity location is further on the delay side than the predetermined crank angle and one or the two from the increase in the fuel injection pressure and displacement towards the fuel injection timing advance are performed when the engine speed or vehicle speed in which the engine is set is equal or higher than the set reference values in the case where the heat generation rate center-of-gravity location is further on the delay side than the predetermined crank angle. Then the fuel economy can be improved by maintaining the heat generation rate center-of-gravity location at a predetermined fixed value regardless of the engine load and/or engine speed, while avoiding an increase in noise and vibration with which make the user to feel uncomfortable.

EFFECT: fuel combustion controlling in the internal combustion engine to reduce noise and vibration.
