摘要：
A fuel injection system utilized with an engine having pre-combustion chambers, main combustion chambers, a fuel metering and quantity distribution valve, a suction tube and an air measuring member are described in further detail hereinafter. The fuel metering and quantity distribution valve has a control slide member which is controlled in its displacement by the air measuring member. The control slide member controls the fuel metered to the engine. The fuel metering and quantity distribution valve has a first differential pressure valve associated therewith which maintains the pressure difference between the fuel pressure prevailing upstream and downstream of the fuel metering location constant during injection. Structure is provided to change the pressure difference in dependence on engine parameters.
