PURPOSE:To control an actuator accurately with correspondence to the cooling water temperature in a system where the fuel injection pump having reciprocal piston will function as a choke mechanism or an acceleration pump when starting or accelerating. CONSTITUTION:Starting or accelerating fuel injection means 6 has a solenoid fuel injection pump 23 where the inlet 17 is opened through a path 18 to the float chamber 3 while the outlet 19 is opened through a path 22 to the intake path 1c of carburetor 1. Said pump 23 will reciprocate a piston 27 through control of the solenoid 29 of solenoid actuator 30 thus to eject the sucked and boosted fuel to the intake path 1c. The actuator 30 is controlled by control means 5 in accordance to predetermined program and if the cooling water temperature to be detected through water temperature detecting means 4 is low (or high), the frequency or the magnitude of the pulse voltage to be applied onto the solenoid 29 is controlled to the decreasing (or increasing) side. |
