A drive unit with a drive and an electric machine, the drive being equipped with a drive shaft and the electric machine with a stator and a rotor. The rotor is coaxial to the stator and connected to the drive shaft for the transmission of torque, where the stator and the rotor interact with each other across an air gap, and where the drive shaft causes the rotor to execute a wobbling motion. In a cross section parallel to the drive shaft, the geometric course of at least one of the two surfaces forming the boundaries of the air gap, i.e., the surface of the rotor or the surface of the stator, is designed so that it at least approximates the geometric slowing curve (VR) described by the wobbling motion of the rotor.

A snowmobile is powered by an internal combustion engine. The engine has an exhaust timing control valve, a control unit and a generator. The control unit determines the positioning of the control valve as a function of engine speed. Additionally, the control unit initiates a control valve cleaning cycle when the engine speed first exceeds a first predetermined speed within a predetermined range of engine speeds. The first predetermined speed is desirably an engine speed at which the generator generates sufficient power to render the control unit operable. The control unit retracts the control valve when the engine speed exceeds the upper limit of the predetermined range. Thereafter, the control unit initiates another control valve cleaning cycle when the engine speed decreases below a second predetermined engine speed.

An outboard motor includes a vertical multi-cylinder engine, a fly-wheel magneto device, a partition plate, and a ventilation fan. The vertical multi-cylinder engine is disposed in an engine cover and comprises a crank case and a crank shaft, the crank shaft being rotatably disposed and protruding upward from the crank case. The fly-wheel magneto device is disposed on the protruding portion of the crank shaft. The partition plate is disposed in the engine cover and partitions the inside of the engine cover into an engine air-inlet space and a space including a heat-generating source, the engine air-inlet space being disposed at the upper portion of the engine cover, and the space including a heat-generating source being disposed at the lower portion of the engine cover. The ventilation fan is disposed in the lower space below the partition plate.

In a failure detection system of coils that produce outputs in response to rotation of a crankshaft of a general-purpose engine (including a power coil that produces an output indicative of the engine speed), the outputs produced by the coils are inputted to determine whether the coils produce the outputs, and it is discriminated that one of the coils (i.e., power coil) has failed when the coil does not produce the output, thereby enabling detection of failure such as wire breaking of the power coil and preventing overrunning of the engine and other such problems.

A multiple-keyed crankshaft and flywheel provides for different ignition timing options for an internal combustion engine. The crankshaft of the engine includes multiple keyways set at designated angular displacements of the crankshaft that correspond with keyways on a flywheel for providing different timing options for the engine. The flywheel may be mounted to the crankshaft by aligning one of the keyways of the flywheel to one of the keyways of the crankshaft related to a particular ignition timing selection.

The invention discloses a high-power motorboat outboard engine flywheel. An outer circumference face, matched with an inner hole of a cylinder body, of a shaft sleeve is arranged to be in a step structure and is composed of an outer layer disc, an outer edge boss and an inner layer disc, wherein the an outer layer disc, the outer edge boss and the inner layer disc are arranged in sequence, the diameter of the outer edge boss is larger than the diameter of the outer layer disc and the diameter of the inner layer disc, and a plurality of sections of cutting string grooves are formed in the outer circumference face of the outer edge boss. When the high-power motorboat outboard engine flywheel is assembled, the outer layer disc of the shaft sleeve is placed in a step small hole of the cylinder body. A plurality of sections of gaps are formed on the corresponding portions of the cutting string grooves of the outer edge boss and a large hole of the cylinder body. A die is composed of an upper die and a lower die which are arranged in a matched mode. An upper convex die is arranged on the upper die, and a lower convex die is arranged on the lower die. The shaft sleeve and the cylinder body are connected into a whole through an upper baffle block, a lower baffle block and a rotation-stopping baffle block, wherein the upper baffle block and the lower baffle block are formed on the outer edge boss. According to the connecting method, a die stamping method is adopted, the shaft sleeve and the cylinder body are firmly connected into the whole, the size of the shaft sleeve is obviously decreased, consumed materials of the shaft sleeve are reduced, and precious resources and machining work hours are saved.

An engine has a crankshaft journaled on an engine body. The crankshaft has an end portion that extends outward beyond the engine body. In some embodiments, a flywheel has a hub portion and a wheel portion which are unitarily formed with each other. The hub portion has a cylindrical shape that extends generally along an axis of the crankshaft and is coupled with the end portion of the crankshaft. The hub portion has a uniform thickness and a nut or bolt fastens the hub portion onto the end portion of the crankshaft. In other embodiments, the flywheel has a wheel portion and a coupling portion which are unitarily formed with each other. The coupling portion extends over the end portion of the crankshaft and intersects an axis of the crankshaft. Multiple bolts fasten the coupling portion onto the end portion of the crankshaft.
