车用柴油机喷油泵和喷油器的常规校准,必须按原车规定的数据进行。但在使用过程中或检修时,常常遇到查阅不到喷油泵和喷油器有关调整参数的情况,这在老旧车辆、杂牌车和进口车中还是比较常见的。尤其是在那些技术资料比较欠缺的用车单位和用车地区,上述情况就更为突出。 Conventional calibration of vehicle diesel injection pumps and injectors must be based on the data provided by the original vehicle. However, during use or overhauling, it is often encountered that the adjustment parameters of fuel injection pump and fuel injector can not be inspected, which is still common in old vehicles, brand-name vehicles and imported vehicles. Especially in those areas where there is a lack of technical data for car units and car use, the above situation is even more conspicuous.
