Abstract
PURPOSE: To prevent the state of exhaust gas from deteriorating and to warn up an engine stably by a method wherein in warming up an engine, also, under an A/F (air-fuel) ratio control through the increment system of a carburettor, large pulsations are not allowed to appear to the A/F control.
CONSTITUTION: In an idle warming-up, a desired number of rotation Nset and a desired suction negative pressure Vcset are determined in proportion to an engine temprature TW, and a throttle actuator 7 and a fuel solenoid 5 are controlled so as to take these Nset, Vcset. And, in warming-up operation, control in proportion to TW under the number of rotation N is stopped by the tansfer to an acceleration pedal operation and control to a fuel solenoid 5 is executed by the use of the data DF calcuiated on the basis of the number of rotation N and the suction negative pressure Vc by sensors 10, 8. The desired values Nset and Vcset are data induced from the engine temperature and cause no pulsations. Thus, the A/F control characteristics scarcely contain pulsations.
