摘要： PURPOSE: To improve the responsiveness of a spill mechanism which is adapted for reducing the pressure of fuel in a pump chamber so as to interrupt the fuel supply for a fuel injection valve, by closing part of cylinders by a solenoid valve to cut off a spill passage when fuel is supplied for a fuel injection valve.
CONSTITUTION: A spill mechanism 14 consists of a free piston 16 serving as a valve body which opens or shuts off the communication between a pump chamber 9 and a spill passage 15, a gas sensor 17, namely, a valve position detecting mechanism which detects the position of the free piston 16, and a solenoid valve 18 which controls the driving of the free piston 16. The free piston 16 slides inside a cylinder 19 which is disposed inside a pump casing 7. The cylinder 19 has at the left end thereof a fine hole 191 which is communicated with the pump chamber 9, at the right end thereof another fine hole 192 which is opened and closed by the solenoid valve 18, and an annular groove 193 on the internal periphery thereof. The annular groove 193 is communicated with the spill passage 15. Such constitution may improve the responsiveness.

An electrode extension 184 is formed on one such as the inner peripheral surface 11b' of the holes 11a', 11b' to form an electrostrictive element 200. Many elements 200 are laminated so that they are displaced at 180° to communicate between the holes 11a' and 11b'. Electrode surfaces are formed on the inner peripheral surfaces of the holes 11a', 11b' which communicate with one another, thereby forming a dielectric ceramic actuator.

摘要： PURPOSE:To provide constantly a suitable swirl according to the operation condition by detecting the variation rate of torque and controlling a swirl control valve on the basis of the detection. CONSTITUTION:Torque is detected by a pressure detector 920 to check a trifle torque variation rate DELTATe with respect to a trifle variation rate DELTAtheta of the opening angle theta of a swirl control valve 4. If DELTATe is larger than (vr)1 (a value specified in accordance with the operating condition), a current through the solenoid coil 75 of a control valve 7 is increased to pull down a plunger 76 to intensify the negative pressure from a vacuum pump 8, then the opening angle of the swirl control valve 4 is reduced so that the swirl may be weakened. If DELTATe is equal to or a little smaller than vr1, the angle theta will not vary and if DELTATe is clearly smaller than vr1, the angle is varied by DELTAtheta in the reverse direction.

摘要： PURPOSE:To prevent over-revolutions with a simple construction by blocking the fuel passage, which is open to the fuel inlet provided in the cylinder shaft hole formed in a pump housing, with a valve element through a flyweight having centrifugal action when the engine operates at a revolving speed exceeding a specified number of revolutions. CONSTITUTION:Fuel inhaled by a feed pump 3 is supplied to a pump chamber 1a from a discharge port 4. If, at this time, the engine operates within a normal range of revolving speed, a flyweight 23 moves a sleeve 24 a cut lever 27 to the right and the valve element 28 opens the suction port provided in the fuel intake passage 13. Therefore the fuel in the chamber 1a is sent to a pressure chamber 1c through the passage 13 and a suction groove 7a, and upon pressurization by a plunger 7, supplied to the injection nozzle 18 through a distribution port 7b and a discharge passage 14. When the engine attains, on the other hand, a number of revolutions over a certain preset upper limit, the said sleeve 24 and cut lever 27 are moved further to the right, and thus, the valve element 28 blockes the suction hole of the fuel intake passage 13, so that the engine decreases in its number of revolutions.

摘要： PURPOSE:To reduce a shock when a piston is stopped by a method wherein a valve capable of opening and closing a part of a hydraulic hole is arranged at a piston head and the valve is operated to close at least a part of the hydraulic hole before the piston is abutted against a cylinder end surface. CONSTITUTION:At the head part of a piston 2 is arranged a valve 12 depressed in such a direction as being projected from the head part of the piston 2. Thereby, the valve 12 closes the hydraulic hole 7 before the piston 2 is struck against the end surface of the cylinder 4, a pressure in a pressure chamber 5 between the cylinder 4 and the piston 2 is increased and the piston 2 is deccelerated at a position where the force applied to the piston 2 and the pressure in the pressure chamber 5 are balanced, resulting in that the shock generated when stopped can be reduced.

摘要： PURPOSE:To prevent the generation of noises due to knocking of a diesel engine having two intake passages formed in a single cylinder, by providing an intake throttle valve and an outlet of recirculated exhaust gas in one intake passage other than the intake passage that is formed tangentially to the cylinder. CONSTITUTION:In a cylinder head 1, there are formed a first and a second intake passages 21, 22 opened and closed by an intake valve 23 and an exhaust passage 25 opened and closed by an exhaust valve 24. The first intake passage 21 is formed tangentially to a cylinder bore 11 while the second intake passage 22 is formed at a point-symmetrical position to the center of the intake valve 23. Further, a passage opened and closed by an EGR valve 3 is provided for connecting the second intake passage 22 and the exhaust passage 25 to each other, and an intake throttle valve 4 including a butterfly valve 46 opened and closed by a diaphragm means 41 is provided at the inlet of the second intake passage 22. In the above arrangement, control is made by a vacuum control valve 5 such that the EGR valve 3 is closed at the time of idling operation and high-load operation and the intake throttle valve 4 is closed at the time of low-speed operation.

摘要： PURPOSE:To perform a saving of energy and the clarification of exhaust gas, by a method wherein a means for measuring a fuel flow rate is mounted between a relief valve and a jet nozzle, and an electric relief valve for controlling a fuel jet time is installed to a jet line. CONSTITUTION:A means 6' for measuring a fuel flow rate is mounted at an upper stream side of a fuel jet pump 1 or between a relief valve 3 and a jet nozzle 4. A rotary sensor 10, a sensor 11 for the degree of opening of an accelerator, and a means 6 for measuring a fuel flow rate are connected to a control circuit 5, which compares a real fuel flow rate measured with an optimun value of a fuel jet quantity to lengthen and shorten a fuel jet time through regulation of the electric relief valve 3 so as to bring the two values to coincide with each other. This permits the absorption of a fluctuation in a jet quantity due to a seevler change, and enables the achievement of an energy-saving and the clarification of exhaust gas by normally performing an optimum fuel jet.

摘要： PURPOSE:To improve the fuel consumption, exhaust emission and output simultaneously by a method wherein the passage area of an auxiliary suction air passage is changed so as to form optimum swirl in accordance with the running conditions. CONSTITUTION:Swirl correction in response to the engine speed or cooling water temperature of the engine is inputted in advance in a computer 22. Under the running conditions of low engine speed and light load, because high swirl is required, the valve seat 21c and valve port 21d of an electrically operated type valve 21 come nearly close. Because the negative pressure applied to a diaphragm is large, a stay 17 is pulled up in a large way, resulting in fully closing a throttle valve 11 mounted to a shaft 13. Under the running conditions of high engine speed and heavy load, because improved suction efficiency is rather required than swirl, the throttle valve 11 is fully opened so as to bring the pressure at the negative pressure taking-out port 19 of a carburetor 7 near the atmospheric pressure.
