くなる等の難点があつた。 Conventionally, in a water-cooled two-stroke engine, in order to cool the cylinder section consisting of the cylinder block and cylinder head, a system of cooling water jacket is provided in the cylinder section, and the cooling water is circulated through this jacket. The cooling water temperature in the high-temperature heating parts such as the cylinder head and around the exhaust port of the cylinder section is cooled to approximately 100°C to maintain good engine operating performance, and the cooling water temperature in the high-temperature heating parts such as around the cylinder head and exhaust port is cooled to about 100°C, and the cooling water temperature is kept at about 100°C around the intake port and scavenging port. The cooling water temperature in the section is set at 80℃ to improve filling efficiency and scavenging efficiency.
It is desirable to cool down to below. However, since the low-temperature heating section is affected by the heat from the high-temperature heating section, it is necessary to set the heat dissipation area of the radiator large in order to maintain the cooling water temperature below 80 degrees Celsius, as described above. This not only increases the weight of the system, but also increases the cost.Furthermore, the cooling system occupies a large volume, making its layout difficult.
