ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a structure of an air cleaner of a motorcycle.
2. Description of the Background Art
Air cleaners for motorcycle engines are well known. One air cleaner structure for a motorcycle is shown in Japanese Utility Model Registration No. 2537385. In the shown air cleaner, a clean room and a dirty room are arranged in a widthwise direction of a vehicle with a flat plate air cleaner element disposed therebetween. Air is sucked from a rearward direction of a motorcycle via a rearwardly extending intake duct. The air passes into the dirty room, through the air cleaner element, into the clean room, then to the engine.
When an air cleaner is constructed, as in the above-described conventional example, a capacity/size of the dirty room and a length/size of the intake duct all add to the size of the air cleaner in the lengthwise direction of the motorcycle. In order to have an air cleaner which functions sufficiently, a side face of the air cleaner, including the dirty room and the intake duct, is extended in length, thereby making the air cleaner bulky in construction.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an air cleaner of compact construction. Particularly, it is an object of the present invention to provide an air cleaner which has a compact construction in a lengthwise direction of the motorcycle.
It is a further object of the present invention to provide an air cleaner with improved ventilation efficiency.
It is an even further object of the present invention to provide an air cleaner having an intake duct which is less susceptible to invading water or dust.
These and other objects of the present invention are achieved by providing an air cleaner for an engine of a vehicle, said air cleaner comprising: an air intake port extending in a first direction to accept outside air; an air flow path connected to said air intake port for redirecting a flow of the outside air approximately 180 degrees and yielding redirected air into a dirty air chamber; an air cleaner element adjoining said dirty air chamber for filtering the redirected air and for producing cleaned air; and a clean air chamber adjoining said air cleaner element for accepting the cleaned air and for directing the cleaned air toward the engine.
These and other objects of the present invention are achieved by providing a motorcycle comprising: a frame; an engine attached to said frame; a seat attached to said frame; a rear wheel fender attached to said frame; an air intake port extending in a first direction to accept outside air at a first location; an air flow path connected to said air intake port for redirecting a flow of the outside air approximately 180 degrees and yielding redirected air into a dirty air chamber; an air cleaner element adjoining said dirty air chamber for filtering the redirected air and for producing cleaned air; a clean air chamber adjoining said air cleaner element for accepting the cleaned air; and an outlet port connected to said clean air chamber for passing the cleaned air toward said engine.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
