To further improve efficiency in automotive engine systems, it is important to understand the generation of friction in its components. Accurate simulation and modeling of friction in machine components is, amongst other things, dependent on realistic lubricant rheology and lubricant properties, where especially the latter may change as the machine ages. Some results of research under laboratory conditions on the aging of engine commercial oils with different performance levels (mineral SAE 30, synthetic SAE10W-40, and bio-based) are presented in this paper. The key role of the action of pressure and temperature in engine oils’ aging is described. The paper includes the results of experiments over time in laboratory testing of a single cylinder motorbike. The aging of engine oil causes changes to its dynamic viscosity value. The aim of this work is to evaluate changes due to temperature and pressure in viscosity of engine oil over its lifetime and to perform uncertainty analysis of the measured values. The results are presented as the characteristics of viscosity and time in various temperatures and the shear rates/pressures. This paper also includes a Computational Fluid Dynamics (CFD) model, applying the experimental results in the piston ring tribology problem.

“…4,11 Moreover, bioethanol attracts more water from the environment because it is hygroscopic in nature. 12 Secondly, vehicle startup problem can happen in cold weather when the engine is fuelled with pure ethanol which is hard to vaporize. 13 Thirdly, when bioethanol is used to fuel the engine, the tribological effect on lubricant properties and performance resulting from fuel dilution always appears.…”

“…Results showed that formulations specifically designed for use with ethanol significantly reduced wear and rust formation. An 'Aunt Minnie' field test (simulating short-trip/stop-start driving conditions) was conducted using E85 maintaining the sump oil at 49 • C [13] for a total test duration of 6 months. Under such conditions water was shown to accumulate up to 16 per cent while ethanol accumulation was around 6 per cent.…”

Ethanol is considered a potential long-term replacement for gasoline but information on the impact of ethanol on engine lubricant performance is scarce. Therefore, it is of prime importance to investigate the effect of ethanol on lubricants and engines that currently operate on gasoline. A bench-top test programme was undertaken on a modified Plint TE77 reciprocating tribometer to simulate the piston ring and cylinder wall interface. The Taguchi statistical experimental design method was used to quantify the effect of ethanol and the associated water contamination on friction with a commercially available fully formulated lubricant. Control factors and potential interactions were selected based on the TE77 capability and typical gasoline engine operating conditions. The statistical results show that while independently ethanol does not significantly contribute to friction reduction, the independent contribution from water is moderate when compared with the combined effect of ethanol and water. The water-temperature and load-speed interactions provide a small contribution to friction reduction while the ethanol-load and temperature-load interactions contribute moderately to the same.
