DIAGNOSTICS OF DIESEL ENGINE REFRIGERATION ELEMENTS AND WAYS OF INCREASING TECHNICAL AND ECONOMIC INDICATORS

The reliability of automotive equipment is its ability to perform constructively laid down functions without additional labor and material costs to maintain an able-bodied condition for a long time. Due to the fact that the quality of automotive equipment is characterized by its reliability and performance, increasing the level of reliability is an urgent task at the present stage of development of the technical operation of agricultural equipment. In addition, increasing the reliability of automotive vehicles is a promising way to reduce production costs, since the operation of more reliable equipment requires less labor and material costs. In the restored FS, the stabilization of the initial parameters during operation depends on many technological factors. The main reasons are those that greatly affect the reliability and have a wide range of characteristics under repair conditions. Changes in the technical condition of diesel engines during operation have a great impact on the indicators of fuel efficiency and toxicity of exhaust gases, with the former accounting for half of the resource consumption in agriculture. In order to achieve the necessary environmental and economic performance indicators of an autotractor diesel engine, its characteristics and fuel supply parameters should be adjusted in accordance with the operation and operating mode of the engine. Such a solution will make it possible to change the required parameters and characteristics, thereby ensuring the required nature of the flow of such fuel supply processes as spraying, mixture formation and combustion in each mode of operation. For efficient fuel injection into a diesel cylinder, it is necessary to have a significant reserve of fuel pump performance. Accordingly, a decrease in productivity can lead to a decrease in the amount of cycle feed. Based on the determination of the fuel consumption in the low pressure line of the system, the following tasks can be solved: - assess the technical condition of the fuel system in operation; - to optimize the balance of fuel supply in the experimental FS of the accumulating type and thereby reduce the power consumption for the operation of the system.
