Abstract
An improved air intake passage arrangement for use on an internal combustion engine is disclosed wherein intake passages are integrated with the crankcase such that an outer wall of the crankcase defines an inner wall of the intake passages. This construction minimizes the size of the engine and promotes heating of the air flowing within the intake passages. In addition, depending upon the location of the fuel supply lines, the air intake structure of the present invention can enhance the vaporization of the fuel sprayed therein.
