摘要： Substances in external EGR gas are smoothly guided to a combustion chamber. An intake passage includes: a main intake passage including intake ports and communicating with a combustion chamber and having a supercharger interposed in the main intake passage; and a bypass passage branching off from the main intake passage upstream of the supercharger, and connected downstream of the supercharger; a flow rage adjustment valve changing a cross-sectional flow area of the bypass passage. The bypass passage is provided above the main intake passage, and includes an upper passage to which an EGR passage is connected.

摘要： A 2-cycle, direct-injection diesel engine configured to accommodate low cetane diesel and jet fuels. The engine includes combustion chambers having surfaces which are operable at high temperatures during engine operation to increase the combustion rate of low cetane fuels. The engine is further configured to reduce starting times in cold and/or low pressure situations such as those experienced during attempts to restart a plane engine at relatively high altitudes.

摘要： An impeller for pressurizing an intake air of an engine is provided on a left side end portion in a supercharger rotary shaft of the supercharger. The power from the engine is transmitted to a second sprocket, which is provided on a right side end portion of an input shaft of a speed increaser, through a chain to thereby allow the supercharger to drive. The second sprocket is removably fitted to the input shaft by means of a bolt. The supercharger rotary shaft, the input shaft, the second sprocket and the bolt are all accommodated in a supercharger casing. The supercharger casing has a right side end face formed with an access opening through which access can be made to the second sprocket and the bolt from an axial direction.

摘要： A turbo-charging system of an engine comprising: a central body on which a turbine and a compressor, both keyed on a same shaft, are mounted; and at least two flange diffusers connected to two Venturi tubes comprised in the central body and ending with nozzles. The turbocharging system is interposed between the engine air filter and the engine throttle unit, the turbine receiving from the nozzles the engine intaking air at the output of the air filter whose flow determines the handling of the turbine and, through the shaft, of the compressor.

摘要： A supercharger assembly includes a supercharger in series with an engine that has a crankshaft and has an air intake manifold defining a plenum through which air flow is provided to the engine. A supercharger is upstream of the plenum in air flow to the engine and has a first rotor rotatable with a first shaft and a second rotor rotatable with a second shaft. The supercharger assembly also includes an electric motor-generator that is selectively alternately operable as a motor and as a generator, and a planetary gearing arrangement having a first member operatively connected to the electric motor-generator, a second member connectable to be rotated by the engine crankshaft, and a third member operatively connected for rotation with the first shaft. The supercharger assembly has only two selectively engageable torque-transmitting mechanisms and a control system configured to control the electric motor-generator and the torque-transmitting mechanisms.

摘要： A drive system includes a drive belt, an engine, a motor, and a supercharger for delivering compressed air to an intake of the engine, and a controller for setting the operational mode of the drive system. The engine and motor are selectively engageable with the drive belt, and the supercharger is selectively engageable with the motor. A method of controlling an operational mode of such a drive system includes detecting a throttle position. Thereafter, the method includes selectively engaging the engine with the drive belt or the drive belt with the motor or the motor with the supercharger, based at least in part on the throttle position.
