Abstract
An engine of a construction vehicle is controlled by a system which includes an engine control operation transmitting mechanism having a loose spring means and connecting a fuel control lever and a governor control lever; a decelerator cylinder accommodating a piston therein and having a spring for biasing always the piston on the opposite side of a pressure chamber defined thereby and on the side of the spring a piston rod connected through a york having an elongated hole formed therein to said transmitting mechanism; a solenoid valve adapted to supply the fluid under pressure delivered by a hydraulic pump driven by the engine for exclusive use in control of the system into the pressure chamber of the decelerator cylinder, and cut off the fluid supply; and an electric circuit for controlling the solenoid valve. The above-mentioned decelerator cylinder is so arranged, when the piston is not subjected to the fluid pressure force, as to transmit directly the operation of the fuel control lever to the governor control lever, while when the piston is subjected to the fluid pressure force, to set the governor control lever at a decelerating position even when the fuel control lever is held at a full speed running position, thereby reducing the number of revolutions of the engine to those in the idling speed condition.
