Abstract
An outboard motor is provided, the motor including a V-multicylinder engine arranged horizontally and an intake silencer arranged above the engine. The V engine has an engine block including cylinder blocks extending in a V configuration, forming an opening to the rear of the outboard motor. The intake silencer is arranged above the engine block to match the shape of the V engine. The intake silencer has two inlets opening rearwards of the outboard motor and one outlet positioned between the inlets for introducing air to combustion chambers of the cylinder heads. The two inlets are positioned above the cylinder blocks in a V configuration, respectively.
Claims20
An outboard motor comprising:
- a V engine arranged in a horizontal direction, the engine having an engine block provided with two cylinder blocks extending in a V configuration and forming therebetween an opening which opens to the rear of the outboard motor, a skirt integrally formed with the cylinder blocks and housing a crankshaft arranged vertically, and two cylinder heads provided on ends of the cylinder blocks to define a plurality of combustion chambers;
- and
- an intake silencer having two inlets positioned above the cylinder heads and forming an opening therebetween which opens rearwards of the outboard motor for taking air in, and one outlet positioned between the two inlets for letting the inlet air out to supply it to the combustion chambers.
An outboard motor comprising:
- a engine cover defining an engine room and having an air intake opening;
- an engine disposed in the engine room;
- an air intake guide disposed within the engine cover and having one end communicating with the air intake opening of the engine cover and another end opening into the engine room;
- an intake silencer comprising at least one inlet positioned above the engine and facing in a rearward direction of the outboard motor for taking air in, and an outlet positioned in the rearward direction of the engine;
- and a throttle body connected to the outlet for supplying the inlet air to the engine.
An outboard motor comprising:
- a V-type engine having a plurality of cylinder blocks arranged to form a V-shaped opening which opens in a rearward direction of the outboard motor, a skirt integrally formed with the cylinder blocks for housing a crankshaft therein, and a plurality of cylinder heads each provided at an end of a respective cylinder block to jointly define therewith a plurality of combustion chambers;
- and an intake silencer comprising an inlet for each of the cylinder blocks, the inlets being positioned above the cylinder heads and oriented to form an opening in the rearward direction of the outboard motor for taking in air, and an outlet positioned between two of the inlets for letting out the inlet air to supply it to the combustion chambers.
