ABSTRACT:
A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which serves to apportion a quantity of fuel corresponding to the aspirated air quantity and to effect good preparation of the fuel-air mixture. The fuel injection apparatus comprises a fuel apportionment valve which is actuatable by means of an air flow rate meter arranged in the air induction tube of the internal combustion engine and an arbitrarily actuatable throttle valve arranged downstream of the air flow rate meter. The air flow rate meter has a circular control body, which is rotatably arranged on a bearing shaft with its outer circumference facing in the opposite direction to the air flow and, being transversely arranged with respect to the air induction tube, opens to a greater or lesser degree an aperture which defines the air induction tube cross-sectional area. The air flow rate meter is moved against a return force in accordance with the air quantity flowing therethrough.
