- Abstract
Modern automobiles equipped with an accumulator fuel-delivery system can fulfill the most demanding operational and ecological requirements. However, when fueldelivery components (predominantly, electrohydraulic injectors) break down, it is difficult to analyze their faults. Therefore, studies aimed to decrease diagnosis time, enhance informativity and accuracy and develop methods for continuous injector’s health control, and fault prediction are topical. The issue is lacking data on the parameters of common rail injector, return line leaks. It makes it difficult to identify extreme conditions of accumulator fuel-delivery system’s injectors. The research aims to determine the relations between injector’s conditions and leakage parameters and to develop methods for identifying individual leaks in order to localize the injector’s faults. The research methods are a set of analytical and experimental researches using existing analytical approaches, tools and equipment and special methods and devices. The research results are dependencies of Common Rail injectors’ conditions on the parameters of individual leaks, methods for determining the parameters of individual common line leaks, equipment applied for implementation of these methods.
