| 摘要 |
A fuel injection device for mixture compressing, externally ignited internal combustion engines, which serves to meter the fuel proportional to the intake air and aspirates the air-fuel mixture. The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.
