Abstract
The invention relates to an apparatus for supplying fuel for acceleration during the warm-up phase of an internal combustion engine. The fuel supplied downstream of an arbitrarily actuatable throttle butterfly valve located in the induction tube of the engine being in addition to the fuel supplied by a fuel supply system. There is disclosed a motion control means which is associated with the butterfly valve and actuated thereby upon opening of this valve. The motion control means further includes electrical contacts disposed in an electrical circuit, electromagnet means in the circuit and other valve means arranged to be controlled by said electromagnet for feeding fuel into said induction tube downstream of said butterfly valve upon closing of said contacts. There are several variants of the control means; one constituted by a flexible bellows and the other by a dash pot.
