A warming-up system is described of a car engine comprising: a carburetor housing including an air intake passage defined inside and a venturi portion formed at a part of the intake passage so as to reduce the cross-sectional area of the intake passage; a main nozzle for injecting fuel into the venturi portion of the carburetor housing; a throttle valve in the intake passage located on the lower-course side of the main nozzle and adapted to be shifted between a closed position where the intake passage is opened to a minimum degree and an open position where the intake passage is opened to a maximum degree; fuel resupply means for feeding auxiliary fuel into the intake passage; the fuel resupply means including an auxiliary nozzle disposed in the intake passage and an electromagnetically-operated fuel resupply pump for delivering the auxiliary fuel toward the auxiliary nozzle; rotation detecting means for detecting the rotational frequency of the engine and delivering an electrical rotation signal corresponding to the rotational frequency; and position detecting means for determining whether or not the throttle valve is in the closed position, the position detecting means being adapted to deliver an electrical open signal when the throttle valve is in the open position.
