Description
Technical field
The present invention relates to cooling engine for motor cycle water field, particularly relate to a kind of totally-enclosed Inner eycle water-cooling structure of cooling engine for motor cycle water.
Background technique
Existing cooling motorcycle engine water generally adopts closed circulation system, and namely cooling water is at a closed space Inner eycle, cooled engine.During engine operation, pressure in the circulatory system is change, when pressure reaches a setting value, cooling water in the circulatory system can enter secondary water tank by an one-way valve, otherwise, when the pressure in the circulatory system reduces to a certain extent, the cooling water in secondary water tank can be filled in the circulatory system by another one-way valve.Like this, the cooling water in the circulatory system remains certain pressure and amount, ensures the reliability of cooling.During engine work, between the circulatory system and secondary water tank, this exchange capacity of cooling water is less, and thus the design volume of secondary water tank is also very limited.
Existing cooling motorcycle engine water, seals with a gasket seal between cylinder head and cylinder body, and this sealing gasket should high temperature, the high-pressure gas of sealing combustion indoor, seals the cooling water in cylinder head and cylinder block passage again, as shown in Figure 1.Because the reliability of same sealing gasket sealing high temperature, high-pressure gas is lower than the reliability of sealing cooling water, therefore, gas leakage in reality and situation that cooling water does not leak happens occasionally.A small amount of gas leakage affects the power performance of motor hardly, therefore, for air cooling engine, can not with comprehend, but for water cooled engine, the combustion gas of a small amount of leakage constantly can enter water-cooling circulating system, the pressure in water-cooling circulating system is raised, finally makes cooling water constantly enter secondary water tank.Due to the finite capacity of secondary water tank, when cooling water acquires a certain degree, can overflow from the vent of secondary water tank, like this, the cooling water in water-cooling circulating system can constantly reduce, and cooling effect is deteriorated, and motor cannot normally can work or damage because of overheated.Therefore, existing structure requires higher to component workmanship, assembly quality and gasket material, and not easily management and control in production in enormous quantities, exists certain risk.
