摘要： Gaskets are placed in joints between adjacent nonferrous metal engine members of a water-cooled engine for an outboard motor, such as a cylinder block, a cylinder head, a crankcase, a mount case and an oil pan, to seal the joints. Each of the gaskets has a base member formed of a stainless steel. The surfaces of the base member are coated with electrochemical corrosion preventing films formed by applying a liquid containing flakes of an aluminum alloy or a zinc alloy and a silicate resin in films and baking the films of the liquid. The electrochemical corrosion preventing films are coated with sealing films formed by applying a liquid containing aluminum flakes and a silicate resin to the electrochemical corrosion preventing films and baking the films of the liquid. The gaskets are prevented from electrochemically corroding despite potential difference between each gasket and the adjacent engine members.

摘要： An intake system in a V-type 4-stroke engine for an outboard engine system is provided. A crankshaft of the engine is disposed vertically, and heads of left and right banks are disposed to face rearwards. The engine is covered with an engine hood. In the intake system, an intake air inlet is provided in an upper portion of a longitudinally flat intake air dispensing box disposed between the left and right banks and a rear wall of the engine hood, and leads to an intake passageway in a throttle body. The inside of the intake air dispensing box is divided by a partition wall into first and second dispensing chambers communicating with the intake air inlet and extending longitudinally. An on-off valve is mounted on the partition wall and is capable of bringing the first and second dispensing chambers into and out of communication with each other. Intake ports are provided in the left and right banks to communicate with the first and second dispensing chambers, respectively. Thus, it is possible to provide an intake system for a V-type 4-stroke engine in an outboard engine system, in which the air-charging characteristic can be changed in accordance with the operation state of the engine, while avoiding an increase in size of the engine hood.

摘要： An outboard motor has an internal combustion engine with a carburetor. The carburetor is designed to extend maintenance interval greatly by preventing or suppressing the deposition of solid matters in the gap between the intake passage and a butterfly-type throttle valve therein. The throttle valve is divided, by a valve axis about which the throttle valve turns, into a first valve part that turns from the downstream side to the upstream side with respect to an air intake direction when the fully closed throttle valve is opened and a second valve part that turns from the upstream side to the downstream side with respect to the air intake direction when the fully closed throttle valve is opened. The first valve part has an edge that moves to the upstream side past bypass ports when the fully closed throttle valve is opened, and the second valve part is provided with a through hole that allows air to flow therethrough at a flow rate necessary for idling when the throttle valve is fully closed.

摘要： Disclosed is an apparatus for controlling a semiconductor laser module wherein despite an increase in laser driving current owing to aging of the laser module, temperature control can be performed accurately so as to render constant the actual temperature of the laser module and prevent a change in lasing wavelength that accompanies a change in temperature. The apparatus includes a photodiode for sensing optical intensity of the laser; an APC circuit for controlling driving current of the laser in accordance with an output from the photodiode; a thermistor for sensing the temperature of the laser module; an ATC circuit for driving an electronic laser-cooling device in accordance with an output from the thermistor; and a current-quantity sensing circuit, which is connected to the APC and ATC circuits, for sensing the driving current of the laser output from the APC circuit. Data obtained by measurement of actual temperature of the laser module in relation to the laser driving current is stored in the ATC circuit in advance. The data obtained by measurement, laser driving current information output from the current-quantity sensing circuit and temperature information output from the thermistor are compared and the driving current of the cooling device is set, based upon the result of the comparison, in such a manner that the actual temperature of the laser module is rendered constant.
