摘要： A blower housing (14) for use with an engine (10). The blower housing (14) is adapted to receive a stream of intake air, and the engine (10) includes at least one cylinder. The blower housing (14) includes an intake opening (38), an air filter (70) housed within a filter compartment (74), and an air flow duct (82) adjacent to the filter compartment (74). The air flow duct (82) is configured to direct air to the at least one cylinder. The air flow duct (82) includes a first surface (86) and a second surface (90), the first surface (86) being angled with respect to the second surface (90) to deflect the air passing through the duct (82) away from the first surface (86) toward the second surface (90). The first surface (86) separates the air into a first portion and a second portion having deflected particulate matter therein. The duct (82) also has an aperture (96) that allows air to flow from the duct (82) to the air filter (70), and an exhaust window (92).

摘要： A combination speed limiter and transmission interlock system for an engine-transmission power train that includes an internal combustion engine and a transmission, the power train of the type used to power outboard engines and the like. The system utilizes fewer connections, is less expensive, is expected to be more reliable, utilizes a single housing, is easier to manufacture, and uses fewer components than a power train that utilizes separate speed limiter and transmission interlock modules.

摘要： The cylinder head assembly (10) includes a cast member (12), and a substantially planar member (14) that is affixed to an upper end of the cast member (12). The substantially planar member (14) includes apertures (74, 76) to anchor the intake and exhaust rocker studs (79), apertures that receive the intake and exhaust valve, and apertures that receive the push rod guides. The substantially planar member also has spring locators for the intake and exhaust valve (32) return springs. The cast member (12) is affixed to the engine cylinder (17), and includes cast intake and exhaust manifolds (26), bosses for receiving the intake and exhaust valves (32), a cast pocket for receiving the intake and exhaust push rods (72), and air cooling fins (68). A head cover (16) is disposed on an opposite side of the planar member (14). The invention eliminates the need for two cast components.

摘要： An engine starting device includes a first pulley mounted to the crankshaft of an engine for rotation with the crankshaft. A second pulley is mounted to an arbor that extends into a spring housing containing an elastic member. The elastic member is interconnected with the arbor such that rotation of the arbor in a loading direction loads the elastic member. A belt interconnects the two pulleys and a tensioner is mounted near the belt to selectively apply tension to the belt. When the tensioner applies sufficient tension to the belt, the second pulley rotates in response to the first pulley and crankshaft rotating. Rotation of the second pulley causes the elastic member to become loaded in response to rotation of the arbor in the loading direction. A ratchet wheel and pawl may be used to keep the arbor from rotating in the unloading direction. To initiate start up of the engine, the pawl is removed from engagement with the ratchet wheel. A starter pinion rotates on a helical gear as the elastic member is unloaded. The starter pinion engages the flywheel and causes the flywheel to rotate in the starting direction.

摘要： A four-stroke internal combustion engine (20) is provided. There is provided within an engine housing (28) an oil reservoir (126) and a valve chamber (156) which independently communicate with a crank chamber (124). A strategically placed divider (116) and passageway, located within the engine housing (28), appropriately direct lubricant within the engine housing (28) so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine (20) which includes a cam shaft (98) having a hollow passageway in communication with the crank chamber (124) and the air intake system of the engine. There is also provided an engine housing which can be utilized for engines having different horse power ratings. There is also provided a crankshaft bearing assembly (68, 70) which prevents damage to the bearing upon insertion of the crankshaft (80) into the crank chamber (124).

摘要： An internal combustion engine (12) comprises an energy storing mechanism (14) including at least one elastic member (60) loaded in response to rotation of a rotatable engine member (72). A ratchet member (142), disposed between the elastic member and engine member, rotates in a loading direction in response to rotation of the engine member. The elastic member is loaded in response to the rotation. A pawl (221) can engage with the ratchet member to selectively prevent the ratchet member rotating in an unloading direction opposite the loading direction, to selectively prevent unloading the elastic member. This engagement establishes a line of force, the pawl being positioned with respect to it to urge the pawl and ratchet member toward staying in engagement. A pawl carrier (209) carries the pawl and can remove it from engagement with the ratchet member and. The pawl carrier is positioned to urge the pawl carrier to disengage the pawl from the ratchet member.

摘要： An engine starting and stopping device includes a fist roller (16) selectively abutting the flywheel (46) of an engine for rotation on a first shaft (118) in response to rotation of the flywheel. A second roller (130) abuts the first roller and rotates in response to rotation to he first roller. A second shaft (122) and an overwind clutch (154) couple the second roller with a third roller such that the third roller rotates in response to rotation of the second roller. The third roller (134) abuts a spring housing (82) and causes rotation of the spring housing in response to rotation of the third roller. A spring (94) is housed within the spring housing and is loaded in response to rotation of the spring housing. The overwind clutch slips when the spring is loaded to a preselected level to protect the spring form overwinding. The spring is selectively unloaded to rotate the spring housing in an unloading direction. Rotation of the spring housing in the unloading direction causes rotation of the engine's crankshaft and startup of the engine.
