摘要: A turbine connector (40) in an engine exhaust manifold (30) includes a turbine foot (54) attached to incoming exhaust conduits (42,46). The turbine foot (54) has an outer perimetric edge (72) defining a trapezoidal shape, and inner perimetric edges (86,90) forming exhaust outlets (88,92) from the incoming exhaust conduits (42,46). The inner perimetric edges (86,90) have varied perimetric curvatures largest in finite curvature size upon a web (94) extending between the exhaust outlets (88,92), and together forming an hourglass web profile in a turbine-mounting plane defined by the turbine foot (54).

摘要: A method and apparatus that circumvents belt path obstacles in a Corvette C8 engine for transferring auxiliary power from the engine crankshaft output pulley to a supercharger input pulley by using a drive path transfer apparatus including a transfer input pulley located in the same plane as the crankshaft pulley and connected to it with the main drive belt, a transfer output pulley in a second plane spaced inboard of the first plane including the supercharger pulley, a secondary belt joining the transfer output pulley and the supercharger pulley, and a coupling shaft having the transfer input pulley at one end and the transfer output pulley at the other end, the coupling shaft being rotationally mounted in a two-piece installable bracket secured on the engine block in a location to the side of the obstruction, thereby transferring power from the engine to the supercharger without interference from the obstruction.

摘要: A bayonet joint is to be provided for joining a connector to a tubular body having the connector with bayonet tabs arranged on the exterior of the connector, the tubular body with at least one external bayonet contour arranged on the exterior of the tubular body, and a bayonet ring with inward facing bayonet hooks and at least one inward facing internal bayonet contour. In an assembled state of the bayonet joint the connector, tubular body, and bayonet ring are in a locking orientation relative to one another. The bayonet ring surrounds the connector and the tubular body in the radial direction on the outside, and secures the connector and the tubular body against removal from the bayonet ring.

摘要: An engine equipped with a turbo supercharger has an exhaust manifold coupled to an engine body, a turbo supercharger including a turbine housing demarcating a turbine chamber and a supply path of exhaust air, and a turbine insulator covering the same, and a manifold insulator covering at least the upper surface of the exhaust manifold and the side surface of the exhaust manifold on the turbo supercharger side. The exhaust manifold has a flange as a connection section with respect to the turbo supercharger. The manifold insulator has a cut-away section exposing a joining surface of the flange, and an opening caused by having the interval between the cut-away edge of the cut-away section and the outer peripheral edge of the flange be relatively wider in a predetermined position than in other positions.

摘要: To provide a supercharger mounting structure for an engine that enables a supercharger to be easily fitted to or removed from an engine main body, the supercharger mounting structure for the engine includes a supercharger including a compressing unit for supplying an intake air under pressure to the engine, a speed increasing unit for increasing the rotational speed of an engine rotary shaft and then transmitting it to the compressing unit and a supercharger casing for accommodating the compressing unit and the speed increasing unit. The supercharger casing is removably fitted to a crankcase of the engine.

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.
