Abstract
An engine choke actuation system controls both the opening degree of the choke and throttle valves of a plurality of charge formers during all phases of engine warmup. The engine choke actuation system includes a first device which acts to close the choke valve at the time of engine starting. A second device restricts a degree of closure of the choke valve by the first device depending upon the temperature of the engine at the time of engine starting. The second device also controls the opening degree of the choke valves after engine starting, increasing the opening degree of the choke valve with increasing engine temperature. In addition, the second device controls the fast idle angle of the throttle valves during engine warmup, decreasing the fast idle angle of the throttle valves as the engine temperature increases.
