ABSTRACT:
Each of intake and exhaust valves of an internal combustion engine has a valve retainer provided with a center hole through which the upper portion of each valve stem passes, a flange and a raised portion surrounded by the flange and around the center hole, a groove formed around the center hole, on the raised portion for receiving a pin inserted into a hole formed in the upper portion of the valve stem. The valve retainer can be easily assembled with a valve spring. Further, a cylinder head has an intake port comprising a lateral path which is in shape of a deep pan in cross section and whose height is gradually decreased from the inlet of the lateral path to a vertical path whose lower end has an opening portion to be opened and closed by a valve portion of the intake valve. Thereby, the mixing state of fuel and air is improved.
