摘要： PURPOSE:To enhance the responsiveness of a variable orifice, by disposing a variable orifice sensitive to the atmospheric air pressure or supercharged air pressure, in a relief passage communicating between the operating chamber and fuel reservoir of a fuel injection timing control device. CONSTITUTION:A variable orifice 37 is disposed in a relief passage 33 communicating between the operating chamber 30 and fuel reservoir 4 of a timer piston 28 for controlling fuel injection timing, and is operated in association with the atmospheric air pressure or supercharged air pressure. With this arrangement in which the variable orifice 37 is disposed in the relief passage 37, variations in the opening area of the variable orifice may be made small, thereby the responsiveness of the variable orifice may be enhanced.

摘要： PURPOSE:To prevent production of graphite, white smoke and misfiring when travelling on high land, by providing EGR control valve for controlling the flow in EGR path and a negative pressure regulating valve for feeding fluid pressure into the negative pressure chamber of said control valve. CONSTITUTION:An exhaust gas recirculation control valve 12 will control the exhaust gas flow in exhaust gas recirculation path. An absolute pressure valve 60 will produce constant fluid pressure to the output port 62. A negative pressure regulating valve 30 will feed negative pressure which will decrease with correspondence to increase of load of Diesel engine 1 into the negative pressure chamber 48. Consequently, the negative pressure produced in the pressure regulating chamber 36 is fed into the negative pressure chamber 22 of said valve 12. Since EGR rate is highly compensated with correspondence to the engine load, production of graphite, white smoke and misfiring can be prevented under high land travelling while NOx in exhaust gas can be reduced.

摘要： PURPOSE:To increase accuracy of control for exhaust gas recirculation (EGR) through a less number of part items, by controlling a specific constant pressure valve with an engine condition and driving an EGR valve through the constant pressure valve. CONSTITUTION:An exhaust gas recirculation (EGR) valve 1 is constituted by a valve body 11, diaphragm 12, pressure chamber 15, etc., and provided in an EGR pipe line 5, conducting intake and exhaust pipes (not shown in the drawing), then a constant pressure valve 6 is constituted by a spool valve body 61, diaphragm 63, solenoid coil 65, plunger 66, etc., while the coil 65 is controlled by a variable resistor 31, set to an injection pump 3, and a control circuit 50, to which output of a speed detecting solenoid pick-up 4 is input. Then a communication port 611 of the valve body 61, communicated to either an atmospheric port 601 or negative pressure port 602, is communicated to the chamber 15 through a negative pressure chamber 630. In this way, conduction of an electric current in the coil 65 can lift the valve body 61, and a valve body 11 can be vertically moved by changing pressure in the chamber 630, thus the necessity for a conventional solenoid valve and the like can be eliminated.

摘要： PURPOSE:To prevent the generation of smoke, by using an acceleration compensator to introduce the atmospheric pressure into a diaphragm chamber at the time of the acceleration of an engine to avoid the excessive recycling of exhaust gas. CONSTITUTION:An exhaust gas recycling passage 10 is connected to the exhaust gas inlet port 11 of an exhaust passage 4 and the exhaust gas injection port 12 of an intake passage 3. When an engine 1 is sharply accelerated, a lever speed discriminator functions to supply electricity to a negative pressure changeover valve 31 to disconnect a port B from another port A and connect the port B to still another port C to introduce the atmospheric pressure into the diaphragm chamber 20 of an exhaust gas recycling control valve 13. As a result, the valve 13 is closed to stop the recycling of exhaust gas. According to this constitution, the exhaust gas is prevented from being excessively recycled due to the response lag in an exhaust gas recycling line at the time of the sharp acceleration.

摘要： PURPOSE:To prevent generation of an air bubble in a valve chamber, by setting tension of a spring, pressing the valve body of a feed for a distributor type fuel injection pump to the valve seat, lower than minimum internal pressure of the injection pump under a normal operational condition. CONSTITUTION:Pressing tension of a spring 6, pressig a valve body 5 to a valve seat body 4, is set lower than minimum internal pressure of a pump undr a normal operational condition. In this way, after a seating of the valve body 5 to the valve seat body 4, the valve body 5 is lifted to communicate a feed valve chamber 7a to a distribution passage chamber 2 and balance pressures in the both chambers because pressure in the distribution passage chamber 2, that is, pressure internally of the pump is higher than a preset load of the spring 6. At unloading of the valve body 5 by an unloading piston 5e, an air bubble generated in the feed valve chamber 7a is immediately removed by this internal pressure of the pump simultaneously pressure in the feed valve chamber 7a is always balanced to pressure in the distribution passage chamber 2, then unevenness of a fuel injection quanity and injection timing can be reduced.

摘要： PURPOSE:To prevent a wall of a communicating path affording communication between a fuel injection nozzle and a sub-combustion chamber from deposition and accumulation of fuel spray for reducing the production of HC and smoke by forming the path to diverge toward the sub-combustion chamber. CONSTITUTION:A portion of a sub-combustion chamber 1 provided in a cylinder heat 7 communicates to a main combustion chamber 6 through a communicating hole 5. In this case, a path 3 affording communication between a fuel injection nozzle 2 and the sub-combustion chamber 1 is shaped conically to diverge toward the sub-combustion chamber 1. The vertical angle of this cone coincides with the spray angle of a nozzle 2. Also, the diameter of the cone is the minimum diameter in which the spray does not contact the wall of the cone. Thus, fuel spray injected from the nozzle 2 is prevented from depositing and accumulating on the wall of the communicating path 3 to reduce the generation of both HC and smoke.

摘要： PURPOSE:To make the high-degree compensation possible and produce inexpensively an atmospheric pressure detecting sensor, by comparing the absolute pressure of a vacuum source of a vacuum pump with the atmospheric pressure and making a diaphragm and a potentiometer into one body. CONSTITUTION:A negative pressure sensor 2 driven by a negative pressure pump 1 is constituted with a diaphragm 22, a spring 23, a shaft 20, a brush 201, a sliding resistance material 21, the body 274. A hole 278 connected to the atmosphere is opened in a down case 272, and an atmospheric pressure chamber 279 is formed between this hole and the diaphragm 22. One end of the shaft 20 is fixed to a holder 241 of the diaphragm 22, and the brush 201 is fixed to the other end. When the pump 1 is operated to make a diaphragm chamber 220 negative-pressure, the diaphragm 22 is moved upward against the set load of the spring 23, and simultaneously, the contacting point between the brush 201 and the resistance material 21 is moved upward. When the current inputted to a coil 43 of a control valve 4 is increased, the negative pressure is reduced.
