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.

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： A four-cycle engine for an outboard motor includes an upwardly extending breather chamber which communicates with a projecting portion provided at a lower part of a crankcase and with an induction system via a PCV passage for returning a blow-by gas to intake manifolds. With this arrangement, it becomes possible to remove oil components from the blow-by gas within the PCV passage and hence to return the substantially oil-free blow-by gas to the intake manifolds.

摘要： An outboard motor includes an engine which is tiltable from a first position to a second position, and a drive mechanism connected to the engine for driving a propeller. When the engine is in the second position, the drive means is tilted upward. An auxiliary fuel tank is connected to the engine for storing fuel returning from a fuel injection valve side of the engine. A high-pressure fuel pump is connected to the engine and the auxiliary fuel tank for pumping fuel from the auxiliary fuel tank to the fuel injection valve side of the engine. A water jacket is connected to the auxiliary fuel tank, for cooling the fuel which is stored in the auxiliary fuel tank. A water pump is driven by the engine to supply water from an external water source to an inlet of the water jacket. A first discharge passage is connected to an outlet of the water jacket. An engine cover is provided, which covers the engine, the fuel pump, and the auxiliary fuel tank. The inlet of the water jacket is configured at a lowest portion of the water jacket when the engine is in the second position. The outboard motor also includes a second discharge passage attached to the water jacket, with the second discharge passage being connected to the inlet and being configured to be below the inlet when the engine is in the second position.

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： 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： An engine cooling system for an outboard motor includes a thermostat mounted on an upper surface of a cylinder block to open and close a cooling water passage depending on the temperature of cooling water inside the cooling water passage, and a relief valve mounted on an upper portion of a side wall of the cylinder block and located adjacent to the thermostat to open and close the cooling water passage depending on the pressure of cooling water inside the cooling water passage. Since the relief valve is located adjacent to the thermostat, the distance (length of an isolated portion of a drainage passage extending) between the thermostat and the relief valve is very small. In the case where the isolated drainage passage portion has no cooling water flowing therethrough, the pressure of the cooling water inside the cooling water passage rises until the relief valve is open. When the relief valve is open, the cooling water flows into the drainage passage with the result that a sufficient cooling effect can be attained over the entire area of the cooling water passage including the isolated drainage passage portion.
