Мethod of diagnosis of modern tractor diesels of agricultural purpose
DOI: 10.33868/0365-8392-2022-1-269-14-24
Abstract. The paper presents new the latest method of diagnostics of a diesel engine of an agricultural tractor based on the analysis of data on changes in efficiency and parameters that characterize the process of formation of fuel-air mixture generated by the engine controller. The technique was tested using an original test cycle, during which several engine defects were physically simulated, which led to changes in the conditions and quality of the processes of formation and combustion of the fuel-air mixture. The paper substantiates the choice of operating modes and a set of engine parameters that provide the greatest information and allow you to effectively identify possible damage. The developed technique and the obtained results allow to determine the technical condition of the engine directly in the operating conditions, both for vehicles with a driver and for unmanned vehicles.
Keywords: diagnostics, internal combustion engine, damage, fuel consumption, efficiency, test cycle.
