前言柴油机的高增压化已成为当前的发展趋势,在小型高速到大型低速的整个领域中,无不在发展高增压柴油机,并向更进一步的高增压化稳步顺利地继续进行研究工作。高增压即为大幅度地提高进气压力,使平均有效压力增高。目前,柴油机的平均有效压力P_(me),二冲程的将达到13~15公斤/厘米~2,四冲程的将达到20~25公斤/厘米~2。这样一来,高增压柴油机气缸内的最高燃烧压力将经常很高。因此,柴油机零部件的抗热性、耐久性、噪音以及振动等势必出现问
Foreword High-pressured diesel engine has become the current trend of development, in the small high-speed to large-scale low-speed in all areas, are all in the development of high-pressure diesel engine, and further to the higher hyper-pressure steady and smooth continue to carry out research work. High booster is to significantly increase the intake pressure, the average effective pressure increased. At present, the average effective pressure of diesel engine P me, two-stroke will reach 13 to 15 kg / cm ~ 2, four-stroke will reach 20 ~ 25 kg / cm ~ 2. As a result, the maximum combustion pressure in a high-pressure diesel engine cylinder will often be high. Therefore, the diesel engine parts, heat resistance, durability, noise and vibration will inevitably appear
