Abstract
An electrically controlled fuel injection apparatus is proposed which serves to control an internal combustion engine. The electrically controlled fuel injection apparatus comprises at least one injection valve which is opened via an electronic control apparatus in accordance with operational characteristics of the engine, at least one temperature-sensitive element which is in communication with the electronic control apparatus for the purpose of influencing the fuel injection quantity and one supplementary air valve disposed within a lateral channel which bypasses the throttle valve in the intake manifold, which supplementary air valve has a movable valve member which is actuatable against a return force by means of a member operating in accordance with temperature for the purpose of opening more or less widely the cross-sectional area of the lateral channel, whereby an electric heating device which is capable of being switched on when ignition impulses are present is attached to at least a portion of the temperature-dependent member, and the temperature-sensitive element is disposed within the supplementary air valve, in particular upon a bimetallic spring of the supplementary ai…
