    摘要: A two-cycle engine includes an engine body having at least one cylinder, the cylinder having an exhaust port and at least one scavenge port disposed generally in opposed relation to the exhaust port. A piston is received in the cylinder for reciprocal movement therealong and having an outer peripheral surface for closing the exhaust and scavenge ports during the reciprocal movement thereof. The piston has a transverse bore extending therethrough with opposite ends of the transverse bore opening to the outer peripheral surface of the piston. The opposite ends of the transverse bore is capable of being brought into facing relation to the opposed exhaust and scavenge ports, respectively, during the reciprocal movement of the piston. A hollow wrist pin is received in the transverse bore and retained therein, one end of the wrist pin being closed.

    摘要: A two-cycle engine includes a cylinder block having at least one pair of first and second cylinders, the first and second cylinders having a pair of first and second exhaust ports, respectively. A pair of first and second pistons are received respectively in the first and second cylinders for reciprocal movement therealong, each of the exhaust ports being selectively closed and opened by a respective one of the pistons during the movement thereof along a respective one of the cylinders. The first and second pistons are operatively connected to a crankshaft in such a manner that the first and second pistons are reciprocable 180.degree. out of phase along the respective cylinders. A final portion of the duration of opening of one of the exhaust ports overlaps an initial portion of the duration of opening of the other. An exhaust passage has a communicating portion communicating the first and second exhaust ports with each other adjacent thereto.

    摘要: An engine is connected to a sun gear of a planetary gear train via a toroidal type continuously variable transmission; driven wheels are connected to a ring gear of the planetary gear train; and the sun gear and the ring gear are connected to each other by a first clutch. A shifter can connect a second clutch, which is connected to the engine, to a carrier of the planetary gear train or to the driven wheels. When the vehicle is started forward when a failure has occurred, by controlling the engagement force of the first clutch on the basis of the rotational rate of the engine and the ratio of the toroidal type continuously variable transmission and controlling the engagement force of the second clutch on the basis of the rotational rate of the engine while the second clutch is connected to the carrier by the shifter, it is possible to prevent the ratio of the toroidal type continuously variable transmission from changing beyond the LOW ratio or the OD ratio and generating an excessive load.

    摘要: An engine is connected to a sun gear of a planetary gear train via a toroidal type continuously variable transmission. Driven wheels of a vehicle are connected to a ring gear of the planetary gear train. The sun gear and the ring gear are connected to each other by a first clutch. A shifter can connect a second clutch connected to the engine either to a carrier of the planetary gear train or the driven wheels. When the vehicle is started when a failure of the electronic central system has occurred, by engaging the first and second clutches with predetermined engagement forces while the second clutch is connected to the carrier by the shifter, change of the ratio of the toroidal type continuously variable transmission beyond either the LOW ratio or the OD ratio is prevented so as to avoid generating an excessive load.

    摘要: A start control system for an internal combustion engine which is capable of automatically restarting the engine while ensuring excellent startability and fuel economy of the engine, and permits reduction of the size of the system, to reduce the weight and manufacturing costs of the system. An electric motor drives an oil pump. An accumulator accumulates oil pressure delivered from the oil lamp. A hydraulic motor is connected to the accumulator via oil passage and driven by the oil pressure accumulated in the accumulator, for starting the engine. An electromagnetic valve is arranged across the oil passage, for controlling supply of oil pressure to the hydraulic motor. An ECU controls operation of the oil pressure supply control valve to thereby cause the hydraulic motor to start the engine.

    摘要: A two-cycle internal combustion engine having an oblong cylinder and an oblong piston therein. The engine includes two sets of scavenging ports at either end of the oblong cylinder having at least three ports each. Scavenging passages extending to the scavenging ports may be directed at sequentially increasing angles of inclination to the local normal with the cylinder away from the exhaust porting. In this way, flow may be directed across the piston head away from the exhaust porting and then upwardly to return toward the exhaust porting. A domed piston is also disclosed having discrete guide surfaces on the domed surface of the piston to specifically direct incoming air/fuel mixture upwardly from each of the scavenging ports. An element of the cylinder midway in the long dimension of the cylinder extends in the direction of piston movement without porting so as to provide a smooth wall surface. An oblong piston ring mounted within a groove in the piston has a break in the ring coincide with the unported cylinder element to reduce stress and friction.
