摘要： An hydraulic mechanism constructed to facilitate termination of fuel delivery by a fuel injection pump includes a piston slidable within a bore which opens into a chamber communicating with the pump. The piston is biased towards an end wall of the chamber and in the end wall is an inlet port. The piston defines a sealing surface engaging with the end wall about the port and a control valve connects the port with the chamber. When the valve is closed and the piston is in contact with the end wall fuel can be delivered by the pump but as soon as the valve is opened the piston is displaced away from the end wall to absorb the fuel delivered by the pump.

摘要： 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.

摘要： In an individual cylinder control apparatus having a closed-loop control system for controlling an average speed of an internal combustion engine, the operation timing of the engine is detected and a timing signal for each cylinder, showing a predetermined measurement period determined to include at least that part of the period during which torque is produced due to fuel combustion in the cylinder concerned during which no influence arises because of torque produced in cylinders other than the cylinder concerned, is output in response to the result of the detection. In response to the timing signal, difference data representing the difference between the output from each cylinder and that from a predetermined reference cylinder among the cylinders is calculated. Individual cylinder control data related to the supply of fuel necessary for reducing the difference to zero is produced in response to the difference data, and the individual cylinder data is output and provided to the closed-loop control system at a predetermined timing before the next fuel regulating process for the individual cylinders, whereby the fuel quantity for each cylinder is regulated so as to make the respective output of the cylinders the same.

摘要： The fuel in a compression pump chamber, defined by a compression plunger, is expelled by the compression plunger driven synchronously with the rotation of an engine. An injection plunger is driven by the expelled fuel, thus injecting fuel into an injection pump chamber defined by the injection plunger. A timing passage, closed by the compression plunger, is formed in the compression pump chamber, and a metering passage is formed in the injection pump chamber. The timing and metering passages communicate with a timing valve and a quantity control valve respectively arranged in an electromagnetic valve. The timing and quantity control valves are driven by an energization current such that they operate in cooperation with each other, i.e., when the timing valve is open, the quantity control valve is closed. When the timing valve is closed and the compression plunger returns, the injection plunger also returns and fuel is supplied to the injection pump chamber through the quantity control valve, which is open. The quantity of fuel filled in the injection pump chamber is controlled by the time interval during which the quantity control valve is open. The time interval during which the fuel is supplied to the pump chamber through the quantity control valve is calculated so as to correspond with engine conditions.

摘要： Apparatus for the continuous injection of fuel into the intake piping of an internal combustion engine comprises an air pump for delivering an air stream portion deviated from the engine intake pipe, a fuel pump for delivering fuel from a source, a metering device controlled in response to operating conditions of the internal combustion engine and receiving fuel delivered by said fuel pump and the air stream portion delivered by said air pump for mixing said fuel and air stream portion and delivering the same to the intake piping of the engine, in which the supply of said air stream portion to the metering device is interrupted during an operating condition of the engine, preferably a coasting condition of operation of the engine. Interruption of the air stream portion may be effected by a shut-off valve in the conduit delivering the air stream portion from the air pump, responsive to a coasting condition of the engie. Alternatively, this may be accomplished by disabling the air pump during a coasting operation of the engine and enabling the air pump at the end of such operation.
