苏联柴油机制造面临的最重要任务之_-,是进一步提高机车柴油机装置的效率,并同时减小其重量和限界尺寸指标。为解决这一问题,必须制造高强化柴油机,以减少燃油燃烧时冷却水、机油、废气带走的热损失。降低冷却介质热损失的有效方法,一般可分为两种:一是提高传热表面热阻(采用金属陶瓷涂层、陶瓷和耐热钢等);另一是提高发
The most important task faced by the Soviet Union in the manufacture of diesel engines is to further improve the efficiency of the locomotive diesel engine while reducing its weight and limit size. In order to solve this problem, it is necessary to manufacture a highly-intensified diesel engine to reduce the heat loss caused by cooling water, engine oil and exhaust gas when the fuel is burned. Effective methods to reduce the heat loss of the cooling medium can generally be divided into two kinds: one is to improve the heat transfer surface thermal resistance (using cermet coating, ceramic and heat-resistant steel, etc.); the other is to improve hair
