FIELD: engine building; control systems.
SUBSTANCE: invention can be used in fuel management systems for internal combustion engines. Disclosed are methods and systems for reducing fuel supply errors caused by pressure pulsation in a fuel rail of distributed fuel injection. Pressure pulsations occur due to pressure pulsations created in a high-pressure fuel pump supplying fuel into the distributed injection fuel stage and into the direct injection fuel stage. Center of distributed fuel injection pulse is moved to nearest point of pressure measurement in fuel rail in advance direction in order to increase accuracy of supplied fuel pulse.
EFFECT: invention improves fuel metering and eliminates fuel supply errors in a distributed fuel injection system.
