ABSTRACT:
A fuel injection system for mixture-compressing, externally ignited internal combustion engines of the type employing continuous fuel injection with an induction tube. A measuring member, as well as an arbitrarily actuatable throttle butterfly valve are disposed in sequence within the induction tube. A fuel metering and quantity distribution valve assembly is controlled by the measuring member in proportion to air flow rate. Pressurized fluid, preferably fuel, provides a restoring force for the measuring member, via a control pressure circuit. At least one pressure control valve is provided for controlling the pressure in the control circuit in dependence on motor parameters. A heatable control element, operating in dependence on temperature, forms part of the control valve. The heatable control element, which may be a bimetallic spring, acts in opposition to the force of another spring. Instrumentalities are provided for reducing the pressure of the pressurized fluid in the control pressure circuit during the warm-up phase when the engine is suddenly accelerated.
