FIELD: engines.SUBSTANCE: invention can be used in control systems of internal combustion engines (ICE) (1) containing supercharger (12) and fuel injector (10) with direct fuel injection into cylinders. When ICE is changed over to area of supercharging with low frequency rotation, in which temperature of hole wall (3) in cylinder block is low, liquid fuel sticks to surface of wall hole (3) in cylinder block so that lubricating oil is diluted with liquid fuel and released into combustion chamber (4). As a result, abnormal combustion occurs. Present invention proposes method and device by means of which, when ICE is changed over to predetermined region of supercharging with low RPMs, in which occurrence of abnormal combustion is possible, fuel injection volume increases.EFFECT: this allows suppression of temperature of "air-fuel" mixture about TDC of compression and prevention of abnormal combustion.9 cl, 10 dwg |
