An exhaust device of an engine includes an exhaust pipe connected to the engine, a silencer connected to the exhaust pipe and structured of an outer cylinder and an inner cylinder in which plural holes are formed, and a sound absorbing material disposed in a space formed between the inner cylinder and the outer cylinder. The exhaust device further includes a partition wall partitioning the space and supporting the sound absorbing material so that the sound absorbing material does not move in an axial direction of the silencer, and the partition wall includes a continuous hole allowing exhaust gas to flow through an upstream side to a downstream side of the partition wall in the space.

Exhaust device of engine

A two-cylinder V-type OHV engine for outboard motors, which allows space saving in the direction of the width of the engine. A starboard side cylinder bank (RB) has a cylinder (R) and a port side cylinder bank (LB) has a cylinder (L). The first cylinder bank (RB) and the second cylinder bank (LB) are arranged to form a V-shape. A crankshaft (), a single camshaft (), and an idle gear () are disposed such that the crankshaft () drives the single camshaft () via the idle gear ().

Two-cylinder V-type OHV engine for outboard motors

An outboard motor comprises an engine disposed inside an outer cover, an intake unit provided for the engine and including a throttle body disposed in a vicinity of a crankcase of the engine and an intake manifold disposed on a side of the engine so as to extend from the throttle body, the intake manifold having a plurality of intake pipes extending towards intake ports formed in a cylinder head of the engine, and a fuel injectors disposed in substantially intermediate portions of the respective intake pipes.

Outboard motor

An outboard motor has a V-type engine in which in which a plurality of cylinders are arranged in a V-shape, a crankshaft is arranged substantially vertically, and an overhead valve (OHV)-type valve train is mounted. This outboard motor also includes an air intake system in which a carburetor is arranged above the engine and in a space of a V bank between the cylinders.
