With regard to a construction that a fan 41 is provided at one side of an engine 1 and covered by a fan casing 45, and an air cleaner 30 is arranged near the fan casing 45 and at a side of a cylinder head 5 on which an intake port 5a is disposed, a suction port 31a communicated with the inside of the fan casing 45 is provided in a main body 31 of the air cleaner 30. A barrier 46 is provided at a position facing to the suction port 31a in the air cleaner 30. A wall standing toward the fan casing 45 and the cylinder head 5 is formed on the outer surface of the main body 31 of the air cleaner 30. An air intake part is provided on one of side surfaces of a cover body 32 of the air cleaner 30 and the cover body 32 is constructed to be an equilateral polygon. An intake pipe 31k communicating the air cleaner 30 with the intake port 5a of the cylinder head 5 is constructed integrally with a main body 31 of the air cleaner 30.
A superstructure of an engine that a fan is provided at one side of the engine and covered by a fan casing, and an air cleaner is arranged near the fan casing, characterized in that a suction port opening into the fan casing is provided in a main body of the air cleaner.
A superstructure of an engine that an air cleaner is provided which is constructed by housing an element by a main body and a cover body, characterized in that a recess along an outer perimeter of the element is formed on an inner surface of the main body.
A superstructure of an engine that an air cleaner is provided which is constructed by housing an element by a main body and a cover body, characterized in that an air intake part is provided on one of side surfaces of the cover body and the cover body is constructed to be an equilateral polygon.
A superstructure of an engine that an air cleaner is attached to an intake port of a cylinder head of the engine, characterized in that an intake pipe communicated with the intake port is constructed integrally with a main body of the air cleaner.
A superstructure of an engine comprising a breather in an upper portion of a rocker arm chamber, characterized in that a baffle is provided around an air hole of the breather in the rocker arm casing, and a slit is provided so as to open a lower portion of the baffle.
A superstructure of an engine comprising a breather in an upper portion of a rocker arm chamber, characterized in that a reflux passage of the breather and a starting adjuvant injection passage are communicated with each other, and a throttle is provided in the starting adjuvant injection passage.
A superstructure of an engine that air is sucked into an intake port provided in a cylinder head covering an upper portion of a cylinder block, and the air is supplied through an intake valve arranged below the intake port in the cylinder head to a combustion chamber, characterized in that an inner surface of an outside of the intake port is formed close along a direction of a tangential line of an inner perimeter of a cylinder liner of the cylinder block when viewed in plan.
