Patent ID: 8881692

Claim:
A cooling system for an air cooled combustion engine, which comprises: a top plate provided on a cylinder block top portion of the combustion engine, provided with a cooling fan, so as to lie perpendicular to a longitudinal axis of an engine cylinder; an intake side gasket interposed between the cylinder block and an intake unit and extended upwardly to contact the top plate to thereby seal a gap between the top plate and the intake side gasket; an exhaust side gasket interposed between the cylinder block and an exhaust unit and extended upwardly to contact the top plate to thereby seal a gap between the top plate and the exhaust side gasket; and a cooling passage for passing therethrough a cooling air from the cooling fan, the cooling passage being formed by the cylinder block, the top plate, the intake side gasket and the exhaust side gasket, in which the top plate has an end edge facing the cooling fan and is formed with a guide section so as to extend diagonally downwardly from the end edge of the top plate for guiding the cooling air towards the cooling passage.
