In the past ten years, the reliability of domestic fuel injectors has been greatly improved. The table lists the average number of failures and failure values for each period for each evaluated pump. Among them, refers to the average working interval time between two adjacent failures of the product in the reliability evaluation. This indicator directly reflects the number of product failures within a certain period of time, reflecting the usability and reliability of the product. It can be seen from Table 1 that the average number of failures of each fuel injection pump is decreasing, while the MTBF value is constantly rising, especially in the reliability evaluation in 1996.
In addition, according to the statistics of domestic diesel engine and automobile industry users, among the shutdown failures of diesel engines or automobiles, the shutdown caused by fuel injector failure accounts for about one-third. In some cases, this ratio even reaches more than 40%. The main failure modes of domestic fuel injector nozzles For the convenience of analysis and comparison, we divide the 1990s into four periods, that is, the initial period before 1991 is the initial period of work to meet reliability standards within a limited time. During this period, relatively few companies and products participated in the evaluation.
