ABSTRACT:
A fuel injection system for continuous fuel injection into the induction manifold of an internal combustion engine. Upstream of the main throttle, there is disposed a baffle plate on a pivoting lever which act as an air flow rate meter and displaces the slide valve of a fuel metering assembly in proportion to the air flow rate. An electromagnetic actuator, attached to the induction tube, has a movable armature on which there is disposed a spring. During engine starting at temperatures below approximately 30 degrees C., the restoring force on the air flow rate meter is so low that the force of the actuator spring is able to displace the pivoting lever and the slide valve in the direction of greater fuel delivery, thereby providing cold starting assistance. In other embodiments, the temperature dependence is increased by using a bimetallic spring on the actuator.In a further embodiment, the actuator is attached to the operating lever.
