摘要： A fuel injection pump for internal combustion engines is proposed which has a hydraulic injection instant adjuster, which is exposed to an rpm-dependent pressure established with the aid of a pressure control valve. The control of the pressure control valve is effected by means of varying the control pressure acting upon it. This is accomplished with the aid of a pressure valve, which has a slide exposed to a force variable in accordance with altitude, and the control pressure of the pressure control valve can be modified by means of this slide.

摘要： A fuel control device for an internal combustion engine employing a fuel mixture preparation system in which the amount of fuel is set at will and the amount of combustion air is adjusted automatically. In order to provide sufficient air during abrupt and rapid actuations of the fuel control lever, there is provided a hydraulic differentiating mechanism which senses rapid displacements of the fuel control lever and which temporarily opens a channel leading from a source of high hydraulic pressure directly to the servo motor that pivots the air throttle, thereby causing additional opening of the air throttle and an increased rate of air flow. The high pressure channel is closed gradually after the occurrence of the abrupt fuel change.

摘要： What follows is a description of various exemplary embodiments of a fuel injection system for an internal combustion engine with exhaust gas recycling controlled by a throttle valve situated in the suction tube of the system. The throttle valve is in turn controlled by a servomotor having a displaceable piston connected to the throttle valve. The piston is displaceable against a variable restoring force exerted against it and produces displacements of the throttle valve between two positions, one corresponding to a fully opened position of the throttle valve and closed exhaust gas recycling line, and the other corresponding to a substantially closed throttle valve.

摘要： In the control unit of internal combustion engine, in which the exhaust gas recirculation (EGR) quantity to an intake pipe is adjusted by the EGR valve, an EGR regulator controls an opening degree of the EGR valve according to the fuel injection value. And the EGR regulator decreases the opening degree of the EGR valve quickly to the minimum when the increase of the fuel injection valve in a unit time exceeds a criterial value. Further, an EGR buffer prevents the EGR regulator from quick-decreasing the opening degree of the EGR valve when the fuel injection value is wiggling by the operation of the cruise controller.

摘要： A device for controlling an electromechanical transducer such as a proportional electromagnetic valve, in which a pulse signal having a constant period shorter sufficiently than the minimum response time required for the displacement of the plunger of the proportional electromagnetic valve over its predetermined full stroke is applied to the electromagnetic coil of the proportional electromagnetic valve to superpose a very small vibratory stroke component on the stroke of the plunger, and the duty cycle of the pulse signal applied to the electromagnetic coil is varied so as to urge the plunger in directly proportional relation to the variation of the duty cycle without substantially giving rise to mechanical hysteresis in the stroke of the plunger.

摘要： PROBLEM TO BE SOLVED: To optimize the operation of an EGR valve in a control device of an internal combustion engine set to fully open the EGR valve to avoid the shortage of intake quantity when a command value of injection quantity of fuel suddenly increases. SOLUTION: This control device is provided with an averaging processing part 14 for conducting averaging processing for the injection quantity command value adjusted so that the car velocity is constant during auto cruise, and outputting the averaged value as an injection quantity command value for controlling the EGR valve. Taking notice of the fact that under the auto cruise control in which a sudden increase in required torque is not assumed, the averaging processing is conducted for the injection quantity command value, whereby the EGR valve 2 is prevented from be frequently totally closed in the case where the injection quantity command value just varies little by little.

摘要： PURPOSE:To prevent abnormal combustion from occuring when fuel is short and prevent the damage of an engine, by committing a return of exhaust gas to a suction system when an injection system of a fuel jet engine is decreased in a pressure. CONSTITUTION:Fuel from a fuel tank 1 is fed to a delivery pipe 5 through a fuel filter 2 and a fuel pump 3, and a pressure regulator 6 is connected to the delivery pipe 5 to regulate a fuel pressure. The pressure of the delivery pipe 5 is detected by a pressure switch 8, and when the pressure is below a given pressure, the switch turns ON to excite a solenoid 16, which results in bringing an EGR valve 5 into an OFF state. As a result, exhaust gas is returned to a suction manifold 28 through a pipe 23 to slightly worsen a combustion condition.
