摘要： PURPOSE:To reduce the number of fuel injection valves by improving the atomized air-fuel-mixture state. CONSTITUTION:The air-fuel-mixture supply device is made up by an inclined fuel injection outlet 104 which is located in a Venturi part 103 of an air suction cylinder 101, and an air bleed passage 105 which communicates the air suction cylinder 101 in the upstream of a throttle valve 102 with an atomization room 203a in a nozzle 203 led to the injection outlet 104. When the coil 204 of the fuel injection valve 200 is fed with current, a plunger 202 opens the nozzle hole 201c against the load of a spring 205 at specified intervals for a certain period. Air for atomizing the fuel in the atomization room 203a is supplied into the room 203a through the air bleed passage 105 throughout a speed range from low to high of an engine.

摘要： A throttle valve sensor for internal combustion engines is proposed, which has a first variable resistor dependent on the opening and closing movement of the throttle valve of the internal combustion engine, this variable resistor emitting an electrical signal corresponding to the degree of opening of the throttle valve. A circuit with variable resistors is electrically connected to this first variable resistor, which circuit undertakes a correction of the correlation between the degree of opening of the throttle valve and the electrical signal present at the output of the first variable resistor corresponding to the degree of opening. Hence the ratio between the electrical signal at the output of the variable resistor and the degree of opening of the throttle valve can be simply and accurately set and adjusted according to a predetermined target value.

摘要： PURPOSE:To smoothly guide blow-by gas or the like to an engine by feeding idle air to a groove on the surface of a throttle valve from the bypass passage of the throttle valve via a suction branch path in a valve shaft. CONSTITUTION:A throttle valve 132 is incorporated in a suction path 104 formed on the outer wall 106 of a device main body 102 via a valve shaft 130. A bypass passage 126 for idle suction is formed on the outer wall 106. A suction branch path 140 is branched from the bypass passage 126, and it is communicated to the suction path 104 at the opening 142 on the surface of the throttle valve 132 after passing in the valve shaft 130. A groove 141 with a semicircular cross section is formed on the surface of the throttle valve 132. Idle air is fed to the groove 141 from the bypass passage 126 via the suction branch path 140 then guided to the engine side along the inner wall face of the suction path 104.

摘要： PURPOSE:To permit the compensating control of target idle revolution effectively by a small-size actuator on the assumption that the compensating time of the idle revolution number is the one that a throttle valve is operated, or no load of a carbureter is imposed on the actuator. CONSTITUTION:When the engine key 500 is turned ON, the touch switch 307 inside the actuator 300 goes ON and the idle condition of the engine is detected. Then, the touch detection circuit 401 inside the control circuit 400 goes ON. Then, when accelerating the engine, the touch switch 307 is turned OFF and the circuit 401 sends out a trigger signal, whereupon a signal from the ignition coil 600 is put through the wave form shaper 402 and the f/v converter 403 into the deviation detection circuit 404 and compared with a target voltage. By the difference, the revolution time and driving direction of the motor inside the actuator 300 are determined and thereby the motor is driven and the throttle valve is compensated to a target idle opening degree.

摘要： PURPOSE:To prevent oil or a mixture of oil and carbon from sticking to the inner wall of an intake passage by installing each semicircular projection, going along the circumference, on the surface of a throttle valve. CONSTITUTION:At time of an idling stage, most of idle air flows through a bypass passage 126, and is blown off toward the upstream side of a PCV port 118 from an opening 124. With this, blow-by gas taken out of this PCV port 118 is drawn nearer to the side of a throttle valve 132 along the inner wall of an intake passage 104. Since each semicircular projection 140 installed along the circumference exists on a surface of the throttle valve 132, however, a flow of the blow-by gas is interrupted by this projection and thereby it is led to the side of an engine without almost colliding with an on-off interfering part 134 between the intake passage 104 and the throttle valve 132. In consequence, oil or a mixture of oil and carbon is prevented form sticking to this on-off interfering part 134.

摘要： PURPOSE:To hold proper engine control by providing a throttle valve to control an amount of intake air to an engine and a bypass passage through which idle air passes after bypass of it through the throttle valve. CONSTITUTION:A throttle valve 132 is incorporated in a suction passage 104 in a manner to be openable around a valve shaft 130 to control an amount of intake air to an engine. A bypass passage 126 for idle intake air bypasses the throttle valve 132 and idle intake air is caused to pass therethrough. An opening 124 on the suction passage side of the bypass passage 126 is positioned on the downstream side of the throttle valve 132 in a state in which the throttle valve 132 is approximately in a fully closed state, and is opened along the surface of the shaft 130 of the throttle valve 132. This constitution ensures smooth opening and closing operation of the throttle valve 132 for a long period, and hold proper engine control.

摘要： PURPOSE:To prevent the erroneous operation caused by vibration in a diaphragm operation control valve to control the pressure of injection fuel by restraining the movement of a diaphragm by a frictional force without disturbing normal operation. CONSTITUTION:The fuel sent under pressure is injected from an injection device 5 by the signal of a computer, and the excessive fuel is introduced into a chamber A of a pressure control device 9. When its pressure is higher than a set pressure, it is conducted through a gap between a valve 7 and a seat 6, and returned to a fuel tank via a passage 3. A member 11 with a proper length in the direction of operation is fast fixed on a diaphragm 8, and fitted to a plastic member 12 fixed on a cover 13 to be slided with a small friction of operation. The member 12 is provided with a hole 12a not to change the effective diameter of the diaphragm 8. This construction permits to restrain vibration, prevent the erroneous operation caused by the vibration, and improve the durability of the diaphragm.
