A fuel-air mixture arrangement with an air-compressing supercharger for a combustion engine with continuous fuel injection into the intake pipe which holds an air quantity meter, a pivotal ram flap and a throttle flap are arranged behind each other. The air quantity meter, depending on its deflection, actuates a fuel metering unit. The fuel metering proceeds at constant pressure drop in the fuel. This pressure drop can be varied depending on certain coefficients, and the pressure drop on a valve is varied by a control pressure valve to which controlling variables are applied. The set pressure drop at the metering cross sections of the fuel metering units is kept constant by the valve operated by the control pressure valve. The air quantity meter is located downstream of the air compressing supercharger and the control pressure valve receives the supercharger air pressure prevailing upstream of the throttle flap via a diaphragm unit. The control pressure valve may be connected to a thermostat located in the supercharger air flow. |
