摘要： A first rotary shaft is rotated by a driver and rotatively connected to a first rotary load. A second rotary shaft is rotatively connected to a second rotary load. A hydraulic pump includes a first rotor disposed on the first rotary shaft so as to be rotated together therewith. A second rotor is disposed on the second rotary shaft so as to be rotated together therewith. The second rotor acts so that, when a revolution speed difference has occurred between the first and second rotary shafts, the first and second rotors are each relatively slided on a sliding surface thereon by relative rotation corresponding to the difference, to heighten the pressure of liquid-tightly interposed oil and then supply the pressure-heightened oil. A multiple-disk clutch includes a group of engaging members disposed on the first rotary shaft so as to be rotated together therewith and so as to be movable in the axial direction thereof relative to the first rotary shaft, and another group of engaging members which are disposed on the second rotary shaft so as to be rotated together therewith. The latter engaging members are placed between the former engaging members so as to constitute a multiple-disk clutch, thus making is possible to engage both the groups of engaging members with each other to transmit torque.

摘要： An internal combustion engine having a main combustion chamber connected to an intake port for an air-fuel mixture, and an auxiliary combustion or a precombustion chamber communicated with the main combustion chamber through a plurality of torch apertures. The auxiliary combustion chamber is, before a combustion stroke of the engine, supplied through the torch apertures with an amount of the mixture for pre-combustion therein. A spark plug has a set of electrodes disposed in at least one of the torch apertures for causing the pre-combustion of the mixture in the auxiliary combustion chamber to thereby generate torch jets which are directed into the main combustion chamber to ignite the mixture therein. The torch apertures are arranged such that the residual combustion gases produced during a combustion stroke of the engine and retained in the auxiliary combustion chamber are forced out therefrom through at least one of the torch apertures during a succeeding intake stroke, due to the mixture flowing into the auxiliary combustion chamber through the other torch aperture or apertures.

摘要： A torch-ignition internal combustion engine has a trap chamber formed in the engine cylinder head and communicated with a main combustion chamber through a plurality of torch apertures. An intake port extends through the cylinder head to the main combustion chamber to feed a charge of an air-fuel mixture thereinto when an intake valve is open on an intake stroke of the engine. At least one of the torch apertures is positioned and directed relative to the downstream end of the intake port such that a part of the mixture charge to the main combustion chamber flows through the one torch aperture into the trap chamber during the intake stroke of the engine to simultaneously force out the residual gases produced during a preceding combustion stroke through the other torch aperture or apertures into the main combustion chamber. A part of the mixture fed into the main combustion chamber is forced through the torch apertures into the trap chamber on a succeeding compression stroke to urge any residual combustion gases in the main and trap chambers toward the inner part of the trap chamber remote from the main combustion chamber. A spark plug is mounted on the cylinder head such that the plug electrodes are disposed within the main combustion chamber adjacent to that end of one of the torch apertures which is open to the main combustion chamber to cause an initial spark-ignition of the mixture adjacent to the plug electrodes. The spark-ignition produces a fire which propagates into the trap chamber through the torch aperture adjacent to the plug electrodes whereby the mixture in the trap chamber is burnt to produce a combustion flame which spurts through all the torch apertures into the main combustion chamber to form strong torch jets for the torch-ignition of the mixture in the main combustion chamber.

The nozzle includes a nozzle body and a needle valve slidably disposed in a guide hole of the nozzle body with a spray hole communicating a body seat formed inside the nozzle body and the forward end of the needle valve. A swirl passage is provided around the needle valve for giving a swirl flow influence around the axis of the needle valve to fuel when the needle valve is lifted from the body seat. A straight passage is provided in a portion where the inner wall of the guide hole and the needle valve make sliding contact for giving the fuel a straight flow influence in the axial direction of the needle valve. The two flows are joined prior to passing through the spray hole.

摘要： The invention discloses an internal combustion engine wherein each cylinder includes a main combustion chamber, an intake port opening into the main combustion chamber, an intake valve for opening and closing the intake port, an intake passage communicating with the main combustion chamber through the intake port for charging the lean mixture into a main combustion chamber, a trap chamber with a spark plug, and a fuel injection nozzle disposed in the intake passage and actuatable in response to a signal from a control system to inject a fuel at least one time during the suction stroke, thereby causing a rich mixture to be trapped in a trap chamber to ensure the positive ignition. The fuel is also injected during another stroke other than the suction stroke in which the fuel is completely vaporized, so that the lean mixture, may be charged into the main combustion chamber during the next suction stroke. Thus, the HC emission may be substantially reduced. According to one embodiment of the present invention, the ratio of the quantity of the fuel to be injected during the suction stroke to the total quantity of the fuel to be injected in each cycle of the engine is varied so that the rich mixture (in a minimum quantity but sufficient for ensuring the positive ignition in the trap chamber) may be supplied, as as to further reduce the pollutant emission.
