    摘要: A supercharging apparatus for an internal combustion engine wherein a supercharger is disposed in the intake passage of the engine. A stepwise variable transmission drives the supercharger. The transmission has a plurality of gear stages so that the rotational characteristics of supercharger can be changed. The stepwise variable transmission has a one-way clutch that interrupts the driving relation between a lower gear stage and the engine output shaft during shift-up operation. Therefore, rapid shift-up operation and shockless shift-down operation are obtained.

    摘要: An engine control system having an engine vibration sensor which detects engine vibrations. A control circuit is provided for discriminating engine roughness wherein the engine vibration level is above a predetermined level and for decreasing the fuel supply continuously when engine roughness is not detected, in order to make the mixture leaner, but increasing the fuel supply when engine roughness is detected to make the mixture richer. A detector is provided for detecting a specific engine condition wherein the mixture is enriched for specific purposes. The control circuit is responsive to the output of the engine condition detector and discontinues the roughness control when the specific engine condition is detected.

    摘要: A turbo-supercharger for an engine includes a turbine casing having a turbine scroll divided into a first and second inlet passages. The inlet passages are opened to the engine exhaust passage through first and second inlet ports formed in a mating surface where the turbine casing is attached to the exhaust passage. A shut-off valve is provided in the exhaust passage and has a valve member which is adapted to be seated on the mating surface to close the second inlet port to thereby allow the exhaust gas to flow only through the first inlet passage. The shut-off valve is opened under high speed, heavy load operation so that the exhaust gas is passed through both the first and second inlet passages. A bypass passage is provided in the turbine casing to open at one end to the first inlet passage. A waste gate valve is provided to open the bypass passage when the supercharging pressure exceeds a predetermined value.

    摘要: A rotary piston engine including a casing comprised of a rotor housing and a pair of side housings attached to the opposite sides of the rotor housing to define a rotor cavity. A substantially triangular rotor is disposed in the rotor cavity. The intake system includes a light load intake port formed in one of the side housings so as to open to the rotor cavity, a medium load and heavy load intake ports formed in the other side housing. The light load and medium load intake ports are formed so that they are opened to a working chamber before the chamber is disconnected from the exhaust port. The heavy load intake port is associated with a control valve which is closed under light and medium load operations. The medium load intake port has an effective area smaller than that of the light load intake port and is closed earlier than the light load intake port.
