Abstract

A fuel injection system for a mixture compressing, externally ignited, internal combustion engines employing continuous injection into a suction tube includes a control pressure circuit provided with a throttle. The metering valve is controllably associated with the throttle so that the pressure difference at the metering valve can be changed by changing the pressure difference at the throttle.
