    摘要： A pump shaft support structure includes: a crankcase body which rotatably supports a crankshaft of an engine; a pump shaft which interlockingly rotates with the crankshaft; a crankcase cover which covers the crankcase body; a pump cover which is coupled to the crankcase cover to define a pump chamber therebetween; and a pump rotor which is disposed in the pump chamber and engages with the pump shaft. The pump shaft includes: a supported section which is rotatably supported by the pump cover on the other side of the pump chamber from the crankcase cover; and an insertion section adjoining the supported section in an axial direction. The pump cover has a through bore which passes the insertion section of the pump shaft therethrough. The insertion section of the pump shaft has a diameter smaller than that of the supported section.

    摘要： Provided is a modified two-stroke engine with an intake system having a plurality of removable inserts and a cylinder liner for each cylinder bore. The inserts fit within specific cavities in the engine's cylinder bores and are aligned with corresponding intake ports, upper transfer, lower transfer and central boost ports, in each liner. Certain embodiments may include an exhaust insert for the exhaust port. The exhaust insert can be a single piece or a set of three. Also provided is an engine having a billet aluminum block, forged as one piece, cylinder bores, insert cavities, removable intake inserts, pucks to cover the cylinder bores, a cylinder head base with a ring and a cylinder head cap. The ring prevents the separation of liner from water jacket. The power output of the engine is regulated by varying the size of the inserts. Additionally, methods for assembling, tuning and modifying an engine's horsepower are provided.

    摘要： An air-cooled internal combustion engine includes an engine block, a blower assembly including a blower housing and a fan, and a static cover. The static cover includes multiple air intake openings and is configured to prevent user access to a moving component of the engine. The blower housing is configured to at least partially direct air to the engine block. The fan is configured to move air into the blower assembly through the air intake openings when rotating in a first direction in a cooling mode and to move air out of the blower assembly through the air intake openings when rotating in an opposite second direction in a debris-removal mode.

    摘要： A V-type engine includes two exhaust manifolds connected to two cylinder banks. First and second exhaust ports, respectively provided in the two cylinder banks, are disposed at an inner side of V-shaped lines. Each exhaust manifold includes N branch pipes and a collecting pipe, where N is an integer not less than 2. The N branch pipes are respectively connected to N exhaust ports including at least one of the first exhaust ports and at least one of the second exhaust ports. The collecting pipe is disposed adjacent to N cylinders that are aligned in a direction parallel or substantially parallel to a crank axis direction and extends from one end to the other end of the N cylinders.
