内冷式柴油机是应用缸内冷却技术的柴油机。缸内冷却是使冷却介质进入气缸直接冷却燃烧室部件的冷却方式。它与传统水冷、风冷(均属缸外冷却)的根本区别是以缸内直接冷却取代缸外间接冷却,冷却过程中冷却介质(水)吸热汽化转化为作功介质参与做功,从而将部分冷却散热转化为有用功。因此内冷式柴油机具有冷却效率高、油耗低、机重轻等优点。
Intercooled diesel engine is a diesel engine with in-cylinder cooling technology. In-cylinder cooling is the cooling medium that enters the cylinder to directly cool the combustion chamber components. It is the traditional water-cooled, air-cooled (both outside the cylinder cooling) is the fundamental difference between direct cooling cylinder instead of indirect cooling outside the cylinder, the cooling medium cooling water (cooling) into the working medium endothermic vaporization into the work medium to participate in the work, Part of the cooling and cooling into useful work. Therefore, the internal cooling diesel engine has the advantages of high cooling efficiency, low fuel consumption, light weight and so on.
