摘要： An engine starting device includes a self-starting motor drivable to rotate the crankshaft of an engines, and a one-way clutch operable to permit transmission of rotary motion of the self-starting motor in one direction only to the crankshaft. The one-way clutch includes an inner race operatively connected to an output shaft of the self-starting motor, an outer race operatively connected to the crankshaft, a plurality of ratchet pawls pivotally connected to the inner race and urged by springs against the inner race. The one-way clutch is designed such that, when the speed of rotation of the inner race while being rotated by the self-starting motor goes up to a predetermined value, the ratchet pawls are caused to swing in a radial outward direction under the action of centrifugal force against the bias of the springs and become engaged by the outer race to thereby engage the one-way clutch.

摘要： An outboard motor body case supported on a swivel shaft through a connecting member. The swivel shaft is vertically swingable about a tilting shaft. An engine is mounted at an upper portion of the outboard motor body case, with a crankshaft thereof being oriented vertically, and a flywheel is mounted at a lower end of the crankshaft and disposed between an engine block and the connecting member. A dynamo is mounted within the flywheel, and a starter motor is engaged with a ring gear which is formed around an outer periphery of the flywheel. Thus, since the flywheel having a large weight is mounted at the lower end of the crankshaft, the position of the center of gravity of the outboard motor is lowered. Therefore, it is possible to easily perform a tilting-up about the tilting shaft with a small force. Moreover, since the flywheel is mounted on a power taking-off side of the crankshaft, the torsional vibration of the crankshaft can be reduced.

摘要翻译： 通过连接构件支撑在旋转轴上的舷外马达主体壳体。 旋转轴可绕倾斜轴垂直摆动。 发动机安装在舷外马达主体壳体的上部，其曲轴垂直定向，并且飞轮安装在曲轴的下端并且设置在发动机缸体和连接构件之间。 发电机安装在飞轮内，起动马达与形成在飞轮的外周周围的环形齿轮啮合。 因此，由于具有较大重量的飞轮安装在曲轴的下端，所以舷外马达的重心位置降低。 因此，能够以较小的力容易地进行倾斜轴的倾斜。 此外，由于飞轮安装在曲轴的动力输出侧，因此可以减小曲轴的扭转振动。

摘要： An engine ignition control system comprising an ignition circuit of capacitor charge-discharge type is disclosed in which the ignition timing is determined by controlling the charge-discharge cycle of a capacitor by an output signal from an engine speed detection circuit. An overspeed control circuit stops the ignition when a detection output signal of the engine speed detection circuit exceeds a reference voltage level corresponding to a set engine speed. A slowing down control circuit is actuated in response to an engine slowing down operation start switch for realizing a hypothetical condition substantially equivalent to the one in which the engine speed detection circuit detects an engine speed higher than the actual engine speed thereby to accomplish engine slowing down operation by (a) increasing the reference voltage level gradually, or (b) increasing the output signal level of the engine speed detection circuit stepwise.

摘要： A four-cycle engine including a magnetic detection sensor mounted on a non-magnetic cam shaft pulley which is rotated in operative association with a crank pulley for detecting a plurality of detecting portions formed on the magnetic detection member by coils mounted in the cylinder head. The magnetic detection member is integrally formed with the plurality of detection portions for different uses such that distances from the center of rotation of the cam shaft pulley to the plurality of detection portions are different, and wherein the coils are separately mounted in correspondence to the detection portions. Thus, it is possible not only to take out timing signals for different uses from a single cam shaft pulley, but also to eliminate interference between the discrete coils.
