METHOD TO CONTROL INTERNAL COMBUSTION ENGINE WITH CUTOFF CYLINDERS Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed method comes to cutoff of fuel delivery at uniform alternation of cylinders through each cycle of engine operation. Engine temperature and position of accelerator pedal by means of choke valve position pickup signal are determined and compared with preset values. Delivery of fuel is cut off by blocking control signal supplied to nozzles by electronic unit. Blocking is effected by logic device placed in cut of electric circuits between electronic control unit and nozzles and reading signals from choke valve position and engine temperature pickups. EFFECT: reduced cooling of cylinders with following reduction of negative consequences caused by decrease of working temperature, provision of uniform wear of cylinder-piston group. 1 tbl, 3 dwg
