FIELD: engines and pumps.
SUBSTANCE: fuel injector has spout to be jointed to injection system secured to combustion chamber end wall. It has first channel for flow of preliminary air-fuel mix to combustion chamber, electric insulator, system of plasma generator, second channel for fuel flow into combustion chamber, and third channel for fuel flow to combustion chamber. First channel opens to injector spout center via outlet for preliminary air-fuel mix. Electric insulator surrounds aforesaid outlet. System of plasma generator is arranged stream wise from aforesaid outlet to control ignition and combustion of said preliminary air-fuel mix. Second channel opens outside of electric insulator. Third channel opens outside of second channel.
EFFECT: stable combustion at all rpm irrespective of air-fuel enrichment.
