Abstract
In a spark-ignition two-cycle engine, the inlet end of a cylinder cooling water passage is connected to the discharge port of a cooling water pump by a cooling water pipe. The inlet end of a cylinder head cooling water passage is connected to the discharge port of a cooling water pump by a cooling water pipe. The outlet end of the cylinder cooling water passage is connected through a thermostat to the upper end of a cylinder cooling radiator, and the outlet end of the cylinder head cooling water passage is connected through a three-way valve to the upper end of a cylinder head cooling radiator and a pipe fitting. Upon the increase of the temperature of the cooling water for cooling the cylinder head to a predetermined temperature, a CPU provides a control signal to a servomotor to close a port of the three-way valve connected to the pipe fitting and to open a port of the three-way valve connected to the cylinder head cooling radiator.
