Title:
ENGINE REVOLUTION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS55107033
Kind Code:
A
Abstract:
PURPOSE: To improve starting performance of an engine, by connecting a solenoid coil with a power source, in cranking up a vehicle, through a bypass circuit without resistance.
CONSTITUTION: A switch 24 is closed when temperature of engine cooling water is below a preset level. As an ignition key is turned to crank up a vehicle, a switch 23 is closed and an ingintion coil 22 is connected with a power source B, bypassing a resistance R. Since the coil 22 is directly connected with the power source B, a sufficient current flows through the coil 22, even if the voltage is low, to feed a necessary quantity of air from a flow control valve.
