Impact Assessment of Farm Tractor Engine Fuel Injector Damage on Engine Oil Properties

Abstract

<jats:title>Abstract</jats:title><jats:p>It is justified that the problems related to changes in physico-chemical properties, concentration of trace elements in lubricat-ing oil and the impact of these changes and their dynamics on vehicle structural elements should be considered in detail. It is important that empirical data, theoretical relationships and test results should be taken into account. The paper presents re-search results of the selected physico-chemical parameters and the content of metals in samples of the used engine oil. The samples were collected both after the fuel system failure and during the operation of the farm tractor according to the date of changing engine oil assumed by the producer. An instrumental chemical analysis method HDXRF was used to determine chang-es of the content of trace elements Fe, Sn, Cu, Pb, P, Zn, Ca in engine oil. Additionally, changes in physico-chemical properties were determined with the use of FT-IR spectrometry. Courses of these changes were analysed on account of their impact on the utility properties of the engine oil.</jats:p>

Evaluation of the Impact of Tractor Field Works on Changes in Selected Elements of Engine Oils

“…There were slight differences in the nature of this wear according to individual field work. In the previous work of ( Gołębiowski and Zając, 2020) the results for P, Zn and Ca showed a similar nature of the changes, which qualitatively corresponds to the results of this study.…”

“…According to (Napiórkowski and Gonera, 2020) the most common engine failures in tractors are related to the fuel system and turbocharger failures. On the other hand, (Gołębiowski and Zając, 2020) pointed to the problem of fuel system failures and their effects, i.e., fuel leakage into the engine oil, which results in a significant reduction in its viscosity and a lower oil flash point temperature. However, in the case of turbochargers, failures are most often related to the abrasive wear of the bushings and the turbocharger shaft (Kaszkowiak et al, 2015).…”
