Abstract

To improve engine output and low fuel consumption by effectively reducing intake air resistance of an air intake system in an engine of a motorcycle and a motor-tricycle. In these motorcycle and motor-tricycle for mounting the engine E on a car body frame 15 by setting the axis of a cylinder bore 35a of an engine body 33 almost horizontal, a throttle body 46 is interposed in the middle of the air intake system 47 reaching an inlet port 38 of a cylinder head 36 from an air cleaner 23 arranged above the cylinder head 36, and the air intake system 47 is constituted so as to descend downstream at a steep gradient.

Description

technical field [0001] The present invention relates to an engine air intake device in motorcycles and motor tricycles (motorcycles and tricycles) in which the engine is assembled on a body frame so that the axis of the cylinder barrel of the engine main body is substantially horizontal. Background technique [0002] As a motorcycle in which the axis of the cylinder bore of the engine main body is substantially horizontal and the engine is mounted on the body frame, there is known, for example, the motorcycle disclosed in Japanese Patent Publication No. 62-39993. [0003] In the motorcycle disclosed in the above publication, since the air intake system from the air cleaner above the engine main body to the air intake of the engine main body is horizontal as the carburetor installed in the middle, it has The crank-shaped structure is one of the reasons that hinder the reduction of intake resistance. Contents of the invention [0004] In view of this situation, the present ...
