摘要： The invention relates to an internal combustion engine comprising a crankshaft, one or more cylinders including a cylinder head, a piston, a combustion chamber, one or more intake valves, one or more exhaust valves, an intake system configured for feeding intake air to the engine, an exhaust system configured for conveying exhaust gas away from the engine, a pressure charging system connected to the intake system and an exhaust gas recirculation (EGR) system arranged to feed branched off exhaust gas from the exhaust system to the intake system via an EGR conduit wherein: * the internal combustion engine includes a valve actuation device configured to allow for late or early closing of the intake valves in accordance with late or early Miller-type valve timing, and wherein * the EGR system includes a gas feeding device configured to feed exhaust gas through the EGR conduit in modes of operation wherein the pressure in the intake system exceeds the pressure in the exhaust system, * wherein the gas feeding device is a displacement pump and wherein the gas feeding device is arranged so that exhaust gas recirculating in the EGR system during operation of the engine passes the gas feeding device before being mixed with intake air in the intake system. Additionally, a method of improving efficiency of an internal combustion engine is described.

摘要： A supercharger-equipped combustion engine includes a crankshaft extending in a widthwise direction of a vehicle supported by a crankcase and a supercharger disposed above the crankcase. Power from the crankshaft is transmitted through a supercharger transmission to the supercharger. A crankcase body has an opening formed to be opened at the right side in the widthwise direction, and at least a part of the opening is covered with a holder detachably mounted on the crankcase body. The supercharger transmission includes input and output shafts extending in the widthwise direction of the vehicle, and the input and output shafts are rotatably supported at first end portions thereof at the right side by first bearing portions formed in the holder and are rotatably supported at second end portions thereof at the left side by second bearing portions formed in a side wall of the crankcase body.

摘要： A multi-speed drive for a supercharger includes a planetary gear mechanism with a sun gear mechanism, a plurality of planet gears mounted on a planet carrier, and a ring gear, all mounted for rotation on a stationary shaft. A rotary-mechanical drive input is received by either the ring gear or the planetary drive, and a rotary-mechanical drive output is provided by the planetary drive when the ring gear receives the input, or by the ring gear when the planetary drive receives the input. A one-way roller clutch is disposed coaxially with the planetary gear mechanism, between the sun gear mechanism and the stationary shaft. A hydraulically-actuated, clutch assembly mounted coaxially with the planetary gear mechanism on the stationary shaft engages the sun gear and the ring gear to change the gear ratio of the drive.

摘要： A system includes a compressed air system configured to couple to an engine. The compressed air system includes a compression device configured to compress an air flow, a heat exchanger configured to exchange heat with the air flow along a first flow path, and a bypass system configured to flow the air along a second flow path that bypasses the heat exchanger. The compressed air system is configured to selectively flow the airflow along the first flow path, the second flow path, or a combination thereof, to the engine.
