Abstract

The disclosed pathway structure of an engine induction system comprises: an air cleaner (15) disposed above a crank case (13); a carburetor (18) that is connected to an intake pathway that is lead to the front of the air cleaner (15); and an intake tube (19) that connects the carburetor (18) and the intake port of a cylinder head (13B); and has a breather hose (23) that is connected to a cylinder head cover (12A) and that is lead to the front of the air cleaner (15). The breather hose (23) passes above a throttle position sensor (22) in a lateral view, and is disposed in a manner so as to consistently descend towards the cylinder head. As a result, a pathway structure of an engine induction system is provided that achieves an appropriate tube disposition while being compact.

Description

technical field [0001] The invention relates to a structure of an air intake system passage of an engine in a motorcycle and other vehicles. Background technique [0002] In gasoline engines, etc., since the so-called blow-by gas becomes the cause of aging of engine oil, corrosion of metal, and even air pollution, it is returned to the intake side to mix with new air-fuel mixture for combustion, thereby avoiding this state. released into the atmosphere. [0003] For example, in the engine described in Patent Document 1, etc., a breather box is provided on the cylinder head cover, and blow-by gas is introduced from a breather inlet passing through the cylinder head cover through an oil separation chamber and a breather outlet in the breather box. The intake system of the engine. [0004] Also, in vehicles such as motorcycles, there is an engine in which an air cleaner is disposed above the crankcase, and an intake passage is linearly extended forward on the front surface of...
