3.产品柴油机的开发本章阐述为提高柴油机功率,达到单级增压所能获得的最大极限而作的一些工作。虽然在柴油机上安装两级增压的历史已经很久了,例如在1971年就有这方面的研究报告,但在工业中引进两级增压柴油机的进程却很缓慢。一个主要原因就是:增压器在稳定而持续地发展,使单级增压在11.5m/s的活塞平均速度条件下可以得到2.5MPa(25bar)的平
3. Development of a product diesel engine This chapter describes some of the work that has been done to increase the maximum engine power that a single-stage supercharger can achieve. Although it has been a long time since the two-stage turbocharging was installed in diesel engines, for example, in 1971 there was a study in this area, the introduction of two-stage turbocharged diesel engines in the industry was slow. One of the main reasons is that the supercharger is developing steadily and continuously so that the single-stage supercharging can achieve a flatness of 2.5MPa (25bar) at an average piston speed of 11.5m / s
