The paper presents information regarding the progress in the production technology of engine oils and their role in the operation of a reciprocating internal combustion engine. The research part includes monitoring changes in the physicochemical properties of SL/CF SAE 5W/30 EURO IV engine oil during the operation of CI engines fueled with Ekodiesel Ultra diesel and B biofuel, as well as an assessment of their technical condition.Trouble-free operation of modern internal combustion engines fueled with biofuel requires good lubrication, including the interaction (compatibility) of additive packages refining these products [1]. Engine oil, as a structural component, increasingly influences engine performance, its operational characteristics, reliability, durability, and the level of toxic exhaust emissions [2]. Its composition is becoming increasingly complex, thus requiring in-depth laboratory, test bench (engine), and operational research, taking into account the type of fuel [3].
Progress in engine oil production technology over the last decade is largely related to efforts aimed at reducing environmental impact and increasing their durability – the oil change interval.
Furthermore, for over a dozen years, there has been a visible trend in the development of so-called (…)
