FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. When controlling engine (10), exhaust gases are directed from first extreme (31) and first central (33) of four cylinders to first spiral (71) of double-helical turbo-supercharger (290). Spent gases from second extreme (37) and second central (35) of four cylinders are directed to second spiral (73) of double-helical turbosupercharger. During the first condition, all cylinders with one non-uniform ignition operate. First condition includes condition of high engine load. Ignition events in the first extreme and first central cylinders are separated by 360 degrees of the crankshaft turning angle. Ignition events in second extreme and second central cylinders are separated from each other by 240 degrees of crankshaft turning angle. Operation of all cylinders with one non-uniform ignition includes ignition in the second central cylinder through 120 degrees of a turn angle of a crank shaft after ignition in the first extreme cylinder, ignition in first central cylinder through 240 degrees of crankshaft turning angle after ignition in second central cylinder, ignition in second extreme cylinder through 240 degrees of crankshaft turn angle after ignition in first central cylinder and ignition in first extreme cylinder through 120 degrees of crankshaft turn angle after ignition in second extreme cylinder. Invention discloses engine system and engine control method.
EFFECT: technical result consists in increase of output power and improvement of engine fuel economy.
