摘要： In an outboard engine, an electric device is attached, utilizing a cooling water passage cover for closing a recessed part constituting part of a cooling water jacket, to the cover via a boss part, thus providing a compact electric device mounting structure with no such parts projecting from a side of an engine as in a conventional box member. An engine starting apparatus of the outboard engine is provided with an ignition device and a starter motor connected to a battery, and an AC generator is connected to the battery via an electric device having voltage restricting and rectifying functions. When it is cranked by the starter motor or a starter pulley, the engine is started by the ignition device operated by the battery. As it is cranked by the starter pulley while the battery is discharging, the ignition device is actuated by a current generated by the AC generator and rectified by the electric device to thereby start the engine. As a result, the AC generator provided in the engine starting apparatus of the outboard engine can be made small, and high ignition performance can be achieved by either the starter motor or manually.
摘要翻译： 在舷外发动机中，安装有电气装置，利用冷却水通道盖，用于将构成冷却水套的一部分的凹部通过凸台部封装到盖上，从而提供没有这种部件的紧凑的电气装置安装结构 从传统箱体的发动机一侧突出。 舷外发动机的发动机起动装置设置有连接到电池的点火装置和起动电动机，并且通过具有限压和整流功能的电气装置将AC发电机连接到电池。 当起动马达或起动滑轮起动时，发动机由电池操作的点火装置启动。 当电池正在放电时，由起动滑轮起动，点火装置由交流发电机产生的电流驱动，并通过电气装置整流，从而起动发动机。 因此，能够使设置在舷外发动机的发动机起动装置中的交流发电机变小，通过起动电动机或手动地实现高点火性能。

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.

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： A crank angle detector in which a rotary body rotates in association with a crankshaft of an engine and has portions to be detected every predetermined angle and at least one of the portions to be detected is lacking, and first and second pickups positioned near the outer periphery of the rotary body with a fixed angle difference therebetween, for generating first and second pulses each time the portion to be detected passes. When a number of second pulses equal to or more than a predetermined number are detected after the first pulse has been detected, the crank angle detector sets the time the first pulse is newly detected, as a reference position time for a rotating angle of the crankshaft.

摘要： A V-type multi-cylinder 4-cycle engine E accommodated in an engine room in an outboard motor includes a pair of left and right banks. A surge tank is disposed in a space defined between both the banks and connected to two left and right combustion chambers through intake ports. A throttle body is connected to a lower portion of the surge tank and also to an intake silencer mounted in a left space of the engine room through an elbow. A subsidiary tank for supplying a fuel to an injector is disposed symmetrically with the intake silencer in a right space of the engine room. The employment of the above-described layout makes it possible to make an intake device move compact in the 4-cycle engine.
