PURPOSE:To facilitate changing of engine rotation by providing an electrical low rotation setter in addition to an electrical position setter for controlling the rotation of engine than connecting an actuator for functioning the engine throttle selectively to any one of them. CONSTITUTION:When moving a car, a changeover switch 20 is switched to provide a signal from an electric position setter 11 to an actuator 16 thus to drive an engine 18 with proper rotation set through a knob 13. Then the changeover switch 20 is functioned until preparation of work is finished thus to connect the actuator 16 to an electric low speed rotation setter 19. Consequently, the engine rotation is brought to low through single touch thus to reduce fuel consumption. Upon finish of preparation of work, said switch 20 is switched to connect the actuator 16 to the electric position setter 11 thus to bring the engine 18 rotation high and to produce necessary hydraulic pressure. |
