An outboard motor comprises an engine and a cover that covers the periphery of the engine. The cover includes an outer cover that defines an outer appearance and an inner cover that covers the engine inside the outer cover. The outer cover comprises an outer side division structure that can be divided into a plurality of parts, and the inner cover has a structural part providing access to the engine.

Outboard motor

An air intake passage structure includes an outer cover forming an outer wall of an outboard motor, an inner cover disposed inside the outer cover, a first intake port formed in the outer cover, a second intake port formed in the inner cover, an air introduction chamber formed between the outer cover and the inner cover; and an air passage formed inside the outer cover. The air passage includes a first passage part on an upper side of the air introduction chamber, and a second passage part extending downward from the first passage part. The air introduction chamber includes a side portion communicating with the first intake port, and a top portion communicating with the first passage part through an opening formed in the partition wall.

Air intake passage structure

An outboard engine cover structure that covers an outboard engine and includes an inner cover on an inside and an outer cover on an outside. The structure includes a flow space for air formed between the inner and outer covers, an intake formed in a lower portion of the outer cover and configured to take in outer air to the flow space, a communication port formed in the inner cover in a position above the intake, and configured to cause an inner space of the inner cover accommodating the outboard engine to communicate with the flow space, first ribs arranged between the intake and the communication port in the flow space; and second ribs arranged between the intake and the communication port and positioned closer to the communication port than the first ribs in the flow space.

Outboard engine cover structure

A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.

Breather device, and snow removal machine with breather device

An internal combustion engine () fitted with a carburetor () is provided with a fire-resistant cover member () having a front wall (A) facing an air inlet port () of the carburetor, and a breather tube () having an inlet end (A) connected to a crank chamber () of the internal combustion engine main body, and an outlet end (B) supported by the cover member at a position located between the front wall and the carburetor.
