The fuel system largely determines the longevity of a diesel engine. This is due to the great influence of the fuel transfer process on its operating cycle. The operational characteristics, efficiency and ease of starting the engine are determined by the state of the engine power system, which is demanding for a diesel engine and requires careful regulation. The fuel injection process in a diesel engine largely depends on the design parameters of the fuel equipment. They change under the influence of external and internal factors. Reasonable standard terms and volumes of fuel equipment repairs are of great importance for the operation of diesel engines. These issues can be optimally solved only on the basis of statistical and experimental data on the nature and rate of growth, depending on the duration of operating conditions, superior types of wear on the working surfaces of the fuel system parts.
The service life of fuel equipment is determined by the reliability and durability of precision pairs: plunger, pressure valves and injector nozzles. Operational defects of precision parts change by 12-17% such parameters of the injection process as cyclic feed, ignition timing, injection duration, maximum cycle pressure, can worsen the power and economic performance of a diesel engine. Therefore, the problem of improving the reliability and durability of precision pairs is relevant, the study of which is currently receiving much attention.
Especially from precision pairs, pressure valves deserve attention. Their restoration after operation does not require expensive equipment and energy consumption, but the parameters of diesel engines depend to a large extent on their operation. Improving the injection characteristics of fuel equipment that has served its service life with a change in the parameters of the injection valve in the conditions of repair and maintenance workshops is quite affordable.
