前言燃油系统是柴油机上的一个极其重要的系统。燃油喷射过程对柴油机的结构和性能都有很大的影响。为使柴油机工作可靠,性能良好,喷射过程应满足一系列的要求,如:一定的喷射规律,雾化良好,随负荷而变的准确的每循环供油量,无后射现象和空蚀现象,系统中的压力峰值不宜过高等等。因此,在柴油机设计和试制阶段,需对燃油系统作大量的分析计算和实际调试工作。
Foreword The fuel system is an extremely important system on a diesel engine. The fuel injection process has a great influence on the structure and performance of the diesel engine. In order to make the diesel engine reliable and good performance, the injection process should meet a series of requirements, such as: a certain injection law, good atomization, with the load and accurate per cycle fuel supply, no backfire phenomena and cavitation , The system should not be too high pressure spikes and so on. Therefore, in the diesel engine design and trial stage, the fuel system needs a lot of analysis and calculation and actual commissioning work.
