Abstract
An apparatus is proposed which serves the purpose of mixture formation for internal combustion engines, in particular mixture-compressing engines with externally supplied ignition. The apparatus includes an air flow rate meter, which has at least one control body opening the intake tube cross section to a greater or lesser extent in accordance with the air flow to the cylinders, the deflection of which control body directly controls a fuel metering valve. The fuel metering valve is disposed on the end of the control body and extends in a direction pointing in opposition to that of the air flow and is embodied as a needle valve having a metering needle and a metering opening. The metered fuel can be ejected directly downstream of the fuel metering valve via one or more nozzle openings. As a result of the compact, small structure, one apparatus can be associated with each cylinder of the engine directly upstream of the inlet valve and a throttle valve, the various individual throttle valves and the individual control bodies being interconnected and adjustable in common. As a result unequal distribution of the metered fuel-air mixture to the various individual cylinders of the engine is prevented.
