INTERNAL COMBUSTION ENGINE CONTROL DEVICE Russian patent published in 2012 - IPC F02D13/02 F02D15/04 F02D41/02 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises valve closing time control mechanism, compression ratio control mechanism, ignition mechanism and output torque compensator to compensate ICE output reduction caused by shift of actual intake valve closure time toward TDC side. Besides, it comprises reference state determination device to determine intake valve closure reference time, reference compression ratio, and reference ignition time, and control module. Control module controls valve closure time control mechanism and compression ratio control mechanism to match actual intake valve closure time with valve closure reference time as well as to match actual compression ratio with reference compression ratio so that actual compression ratio is invariable. Also it controls ignition mechanism to match ignition time with reference ignition time. Control module allows control over intake valve closure actual time to make it approximate to TDC from reference valve closure time. Besides, it controls output compensation module when actual compression ratio exceeds reference magnitude. Invention covers also various design versions of control device.

EFFECT: higher efficiency.
