Abstract
A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine. The fuel injection system includes an air flow rate member, which actuates a metering and distribution valve. A reservoir is disposed in a pressure control line which branches off from a fuel supply line, by means of which reservoir a flushing valve can be affected in such a manner that below a certain fuel pressure in the pressure control line the flushing valve is opened, as a result of which the fuel supplied to the individual injection valves can flow back through outflow lines to the fuel tank and thus closes the flushing valve above the certain fuel pressure. Above the certain fuel pressure, the electrical circuit of the starter motor is simultaneously closed. Thus, upon starting the engine, all the lines and units of the fuel injection system are filled with fuel, so that a secure start is assured.
