摘要： PURPOSE:To improve the feeling of acceleration by reducing NOx by interlocking the shift detecting mechanism of a change gear with mixed gas increasing mechanism and by stopping the action of the mixed gas increasing mechanism and by stopping the action of the mixed gas increasing mechanism at the time of change gear shifting during acceleration. CONSTITUTION:The air is gradually introduced into a diaphragm chamber 15 by the action of an orifice 13a when a steady running state is transferred to a decelerating state, permitting a throttle valve 8 to be slowly and entirely closed. Hereby, the discharge of HC is reduced. Moreover, a clutch detecting means 19a is turned on when the change gear (drawing omitted) is shifted for acceleration, so that a control valve 14 cutts off a negative pressure passage 14b to cause the air to be introduced into the diaphragm chamber 15 and the throttle valve 8 to be abruptly and entirely opened. Moreover, this causes a pump guide 22, a pump chamber 25 and a pump nozzle 30 to be actuated via a throttle 1 to permit the amount of fuel to increase. Hereby, it is possible to increase the feeling and to reduce NOx.

摘要： PURPOSE:To generate air flow in the discharge gap area and improve ignition performance by providing a noncombustible mixture sump on a spark plug. CONSTITUTION:When mixture is absorbed in the intake stroke and compressed in the compression stroke in an internal combustion, a part of the mixture in a cylinder passes through the space 13 of a spark plug and its communication hole 12 and moves to a sump 11. In this case, flow velocity occurs naer the central electrode 1 and ground electrode 2 of the spark plug by the movement of the mixture. As a result, noncombustible mixture can always reach the discharge gap of the spark plug. Besides, when discharge starts at the discharge gap, the property of ignition is improved and combustion is evened every cycles.

摘要： PURPOSE:To promote fuel atomization in order to enable to strength of a PTC element to be sufficiently sustained, by forming the bore of a mixture stream passage hole in a tapered shape decreasing the diameter of the hole from the upstream side to the downstream side, and by forming the peripheral edge section of the lower surface opening of the hole in an acuate edge shape. CONSTITUTION:An insulator 3 holds a disc-like PTC element 5 so that the latter partitions a mixdture passage 10 directly below a throttle valve 4. A PTC element 5 made of ceramics, generates heat when it is energized so that it is maintained at a temperature around a Curie point. A plurality of mixture stream passage holes 5a are formed in the PTC element in such a tapered shape that the diameter thereof are decreased toward the downstream side. Thus, the atomization of fuel is promoted and the strength of the PTC element is sufficiently sustained.

摘要： PURPOSE:To stabilize the fuel injection amount by shifting the operation body of a control valve apparatus which is constituted of an electrical strain element, according to the elongation and contarction of the electrical strain element and making the effective stroke of a piston which corresponds to the max. length of shift smaller than the whole stroke of the piston. CONSTITUTION:The fuel supplied by a feed pump 3 flows into a space 71 and fills also a space 11. An electrical strain element 5 elongates or contracts when a voltage is applied, and for example, when +500V is supplied, a piston 10 shifts downward by 50mum against the repulsive force of a spring 111. Since the upper edge surface of a needle body 22 is positioned above by the ring-shaped groove 19 of a cylinder 17 at this time, the pressure of the fuel in the space 11 increases to the hydraulic pressure over the repulsive force of a spring 24, and the needle body 22 is pushed downward. Though a clearance is provided between the slidable part 18 of the cylinder 7 and a piston part 221, fuel leak through the clearance is prevented, since transfer of the piston 10 is performed at high speed, and the needle body 22 is pushed downward, and the fuel in the space 71 is jetted-out.

摘要： PURPOSE:To improve a combustion effect while sufficiently mixing fuel and air by providing a fuel injection nozzle on each of a main combustion chamber and a sub-combustion chamber. CONSTITUTION:A relatively large volume of fuel is firstly injected from a fuel injection nozzle 20 into a sub-combustion chamber 11 due to the difference of the opening areas of fuel injection nozzles against a valve lift, and its combustion gas flows through a communication port 10 into a main combustion chamber 9. On the other hand, the fuel injected from a fuel injection nozzle 21 into the main combustion chamber 9 begins to burn firstly in its small quantity. Thereafter, the fluid stream injected from the sub-combustion chamber 11 flows into the main combustion chamber when said fuel starts to increase, and the air within the main combustion chamber 9 and excessive air within the sub-combustion chamber 11 are sufficiently mixed with the fuel injected while delayed from the nozzle 21, allowing highly efficient combustion to be performed.

摘要： PURPOSE:To improve the fuel consumption, exhaust emission and output simultaneously by a method wherein the area of an auxiliary suction air passage is controlled by means of an electric suction air amount control valve. CONSTITUTION:When a detection means detects the decrease of the engine speed or the rise of the cooling water temperature of the engine and consequently sends the detection signal to a computer, the computer issues the instruction to lower the valve part of the electric suction flow control valve 11 or to contract the opening area of the auxiliary suction air passage 9, resulting in producing high swirl, because the mixture is flowed only through a main suction air passage 9. When the detaction means detects the rise of the engine speed, the increase of the throttle opening of a carburetor or the drop of the cooling water temperature, the computer lifts the valve part of the electric suction flow control valve 11. Because the mixture is past through both the main and auxiliary suction air passages, the suction efficiency is improved, though the strong swirl produced by means of the main suction air passage 9 is weaken by the swirl produced by means of the secondary suction air passage 10 and having an opposite direction to said strong swirl.

摘要： PURPOSE:To improve operational performance under cooling or acceleration, by continuously feeding fuel through second injection valve at the downstream of throttle valve toward the heating face of a suction heater under low cooling water temperature or acceleration. CONSTITUTION:When the engine cooling water temperature is lower than 60 deg.C, for example, an electric heater 11 will function by a signal from a water temperature sensor 10 to heat the heating face 11a while when it is lower than 40 deg.C, required amount of fuel is fed continuously through second injector 13 provided at the downstream of a throttle valve 8 toward the heating face 11a to perform fuel spray effectively. Upon exceeding of cooling water temperature above 40 deg.C, fuel supply through second injector 13 is stopped to feed fuel intermittently through first injector 12 immediately above the throttle valve 8. Under acceleration and any cooling water temperature, all fuel is fed through second injector 13 to improve fuel response. Consequently operationability under cooling or acceleration can be improved.

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 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.
