It was suggested to use group D engine oil with advanced properties instead of group V and G engine oils, which are used in locomotive diesel engines today, to improve the performance of the Ukrainian locomotive fleet of railways.A series of comparative laboratory studies of these oil groups was conducted to substantiate this suggestion which proved better lubrication and tribological performance of group D engine oil and allowed its performance tests.Tests conducted on diesel 5D49 for mileage of more then 100,000 km have demonstrated the advantages of group D oils, such as more stable viscosity, neutralizing ,washing and other properties. Studies on the four-ball wear test machine proved better anti-wear, anti-scoring and anti-friction properties of group D engine oil, which appear even after the continuous use of oils in locomotive diesels. Decrease in burning loss of engine oil was recorded, resulting in the decrease of oil fuel consumption for group D by 30-60% vs. the group G oil.According to the results of performance tests, group D engine oil has been recommended for the use in 5D49 locomotive diesels and some advice on its future implementation have been provided.

Laboratorial two-body wear testing was carried out in order to assess effects of polypropylene modification by impregnating it with oils on friction coefficient and wear in comparison to those parameters of unmodified polypropylene, Teflon, and polyamide during operation under conditions of sliding friction without lubrication. Wear behaviour of the tested specimens was investigated using ASTM G77-98 standard wear test equipment. Recording program made it possible to visualise and record the following parameters: rotational speed and load, linear wear, friction coefficient, temperature of the specimen, and ambient temperature. In addition, wear mechanisms of the analysed materials were determined with use of scanning electron microscopy. In the case of the remaining tested polymers, the most important mechanism of wear was adhesion (PP, PTFE, PA 6.6, and PA MoS2), microcutting (PTFE, PA 6.6, and PA MoS2), fatigue wear (PTFE), forming “roll-shaped particles” combined with plastic deformation (PA 6.6 and PA MoS2), and thermal wear (PP). Impregnation of polypropylene with engine oil, gear oil, or RME results in significant reduction of friction coefficient and thus of friction torque, in relation to not only unmodified polypropylene but also the examined polyamide and Teflon.

Fatty Acid Distillate

Palm-based oil properties, which consist of long fatty acid chains, have the potential to replace current mineral oils. Recent studies have shown that palm-based oil has comparable lubricating properties to those of commercial engine oil. However, several palm oil products yet to be discover as lubricants such as RBD Palm Stearin (RBD PS) and Palm Fatty Acid Distillate (PFAD) due to its solid form properties. In this study, both RBD PS and PFAD has been tested for the suitability as lubricant in the tribological experiments consists of anti-wear test and extreme pressure test according to ASTM standards of D4172 B and 2783 respectively. In ASTM D4172 B, test has been conducted with 40kg load and 1200 rpm speed at 75°C in duration of 60 minutes while in ASTM 2783 the temperature and speed are remain constant at 45°C and 1760 rpm in duration of 10 minutes with increasing loads until failure detected. Mineral Oil (MO) has been used as a direct comparison between commercial engine oil and bio-based palm oil. Results shows PFAD has recorded lowest average coefficient of friction (COF), wear scar diameter (WSD) and surface roughness at 0.038, 433µm and 0.188µm in anti-wear test. In the extreme pressure test, RBD PS shows the earliest failure of 4mm wear scar diameter at 126kg followed by palm fatty acid distillate and mineral oil at 130kg and 146kg load.

Hydrophobic Material

A very low-density oil-absorbing hydrophobic material was fabricated from cellulose nanofiber aerogels–coated silane substances. Nanocellulose aerogels (NCA) superabsorbents were prepared by freeze drying cellulose nanofibril dispersions at 0.2%, 0.5%, 0.8%, 1.0%, and 1.5% w/w. The NCA were hydrophobically modified with methyltrimethoxysilane. The surface morphology and wettability were characterized by scanning electron microscopy and static contact angle. The aerogels displayed an ultralow density (2.0–16.7 mg·cm-3), high porosity (99.9%–98.9%), and superhydrophobicity as evidenced by the contact angle of ~150° that enabled the aerogels to effectively absorb oil from an oil/water mixture. The absorption capacities of hydrophobic nanocellulose aerogels for waste engine oil and olive oil could be up to 140 g·g-1 and 179.1 g·g-1, respectively.
