Methodology of diagnosing automotive diesel engines.

Abstract

Diagnosis is an invariable attribute of quality technical inspection and repair. In this regard, the improvement of existing and development of new methods for diagnosing automotive diesel engines remains an urgent task today. Certain elements of diesel units have little effect on the performance of the diesel engine as a whole, which allows them to diagnose and repair in the garage or even in the field, upon detection of the problem. However, it should be noted that diesel engines have quite obvious signs, the appearance of which indicates the need for urgent access to a specialized service center. Because the main indicators of its work (operational, dynamic and economic) depend on the nature of the workflow in the middle of the engine. In this regard, much attention is paid to the diagnosis of work processes. Analysis of methods for diagnosing automotive diesel engines has shown that methods for diagnosing automotive diesel engines complement each other, which provides to find the causes of various types of failures. Thus, in the case of the use of organoleptic methods, you can see the causes of the most serious failures, such as the location of the coolant. And in the case of the use of instrumental methods in combination with computer diagnostics provides the possibility of a comprehensive comprehensive assessment of engine performance. Which, in turn, is possible only with the use of specialized equipment, licensed software and highly qualified workers with the necessary experience.

Key words: diesel engines, automobile engines, diagnostics, diagnostic methodology, technical inspection, repair works.
