FIELD: engines and pumps.SUBSTANCE: invention relates to internal combustion engine start control systems. The internal combustion engine has a throttle for control of volume of suction air and performs starting by means of cranking. The starter switch detects initiation of cranking, and the sensor of cranked shaft rotation angle determines rpm of the engine. The controller actuates a throttle in the closed position along with initiation of cranking. The controller can get both negative pressure at the inlet for fuel evaporation stimulation, and the suction air volume necessary to maintain idle rpm, by means of counting of number of steps or rpm of the internal combustion engine from initiation of cranking and throttle opening from the closed position when the counted number reaches the pre-set value.EFFECT: ensuring of throttle regulation by creation of negative pressure at the inlet at simultaneous feeding of the respective volume of suction air.7 cl, 11 dwg |
