ABSTRACT:
A fuel injection system for an internal combustion engine has an air sensor for metering the intake air flow into the engine and a fuel metering and distributing device hydraulically coupled together. The device includes a plunger rotated by the engine to distribute fuel to respective fuel injectors and axially moved in response to variation in the intake air flow rate to meter the fuel. The axial displacement of the plunger is determined by two opposing hydraulic pressures acting on the opposite ends of the plunger, one of which is varied in accordance with the engine intake air flow rate as detected by the air sensor while the other hydraulic pressure is changed in accordance with the axial displacement of the plunger. Since no mechanical linkage is required between the air sensor and the fuel metering and distributing device, the system can easily be installed in a limited space and, in addition, assure an improvement in the accuracy of the fuel control.
