1、喷射率测定的意义对柴油机的评价可集中于输出功率、燃料费、耐久性及公害(振动、噪音、排出气体)四个方面。从上述四个方面可以明显看出研究气缸内燃烧的重要性。喷射率的测定,特别对于理论燃烧的研究是不可缺少的一个测定项目;另一方面对于燃烧的实际研究,这个数值也是一个极其重要的数据。但是,根据各个不同内容其测定的精度要求有相当差别。其精度要求如表1,由低级精度开始,按照由上而下的次序表示之。
1, the significance of the injection rate measurement The evaluation of diesel engine can focus on the four aspects of output power, fuel costs, durability and pollution (vibration, noise, exhaust gas). From the above four aspects can be clearly seen the importance of studying the combustion cylinder. The determination of injection rate, especially for the study of theoretical combustion is an indispensable measure; the other hand, the actual study of the combustion, this value is also an extremely important data. However, there are considerable differences in the accuracy of the determination according to the different contents. The accuracy requirements shown in Table 1, from the low-precision start, according to the top-down order of said.
