摘　　要：随着发动机日趋小型化,以及发动机的升功率不断增加,气缸内产生的热量也随之大大增加,导致发动机热负荷增加。如果发动机不能及时把热量传递出去,容易造成活塞环烧结及气缸套迅速磨损,产生端磨的不良后果,影响发动机的正常运行,降低发动机的寿命。同时通过进气中冷,能够有效增加进气量、优化燃烧、提升功率、降低油耗。因此,如何提高发动机的散热能力及热传递效果是一个亟须解决的问题,通过匹配合适的水箱是解决发动机散热量的有效方法。通过试验综合评价,分析发动机技术参数和配置,以满足发动机的最佳需求。With the increasing size of the engine and the increasing power of the engine,the heat generated in the cylinder also increases greatly,resulting in an increase in the engine heat load. If the heat can not be passed in time,it is likely to cause the piston ring sintering and rapid wear and tear,affecting the normal operation of the engine and reduce the life of the engine. It can effectively increase the intake air volume,optimize the combustion,enhance power and reduce fuel consumption through intercooling. Therefore,how to improve the engine cooling capacity and heat transfer effect is an urgent need to solve the problem,matching the appropriate water tank is an effective way to solve the engine heat dissipation. It can meet the optimal needs to analyze the engine technical parameters and configuration.
