“…Reducing engine friction through the design of components, materials and lubricants is a critical and relatively economical approach (Wong and Tung, 2016). For engine components, the friction and wear of piston–cylinder linear system are closely related to factors such as oil transport, lubrication model, lubrication additive, surface texturing, surface coating and cylinder linear honing (Lyu et al , 2020; Cheng et al , 2019; Zhang et al , 2018; White et al , 2019; Grabon et al , 2016; Pereira et al , 2017). Zhang et al (2020) established the hydrodynamic lubrication model of the main bearing and analyzed the influence of the balance rate, bearing width and radial clearance on the oil film and friction loss.…”

Purpose This paper aims to investigate the effects of low-viscosity and ultralow-viscosity engine oils on the comprehensive friction and fuel economy of turbocharged gasoline direct injection (TGDI) through simulation analysis and experiments. Design/methodology/approach Numerical analysis models of friction loss for reciprocating, crankshaft and valve train are established. Based on the FAST, the friction loss of 24 specific parts of a TGDI engine was analyzed. Finally, the engine test bench was built, which was used to test the mechanical loss, external characteristics and universal characteristics. Findings Compared with the baseline oil, lower viscosity lubricating oil can reduce the friction loss of nine components to varying degrees. When the viscosity decreases, the friction distribution ratio of reciprocating, crankshaft and balance shaft will gradually decrease. The proportion of reciprocating when using 0W12 is reduced by 4%. Tests have shown that ultralow viscosity engine oil reduces torque loss by up to 15.74% (2,000 rpm, full throttle), but its fuel consumption rate becomes higher in low-speed and high-torque conditions. Originality/value This work helps to understand the effect of lubricating oil characteristics on the comprehensive friction performance of the engine.

“…In a synthetic ester, the ester molecule is composed of at least one carbonyl moiety and one alcoholic moiety, which is prepared from carboxylic acid and alcohol by means of chemical synthesis . At present, the most widely used synthetic esters in lubrication engineering can be divided into four categories, monoester, diester, polyol ester, and aromatic carboxylic ester according to the number and position of ester groups in synthetic ester molecules. , Compared with vegetable oils, synthetic ester oils have advantages such as good low-temperature and viscosity-temperature performances and excellent friction-reducing and antiwear properties. − Due to these remarkable advantages, they have been widely used in aerospace and automobile industries, food processing, etc. Synthetic ester oils are supposed to be one of the most valuable and promising lubricants for future lubrication engineering. , With the rapid development of modern industry, the design of high-performance synthetic esters is highly desired.…”

The work reports on the physicochemical and tribological properties of gallate ester oils prepared from fully renewable resources, such as gallic acid and fatty acids. The ester structures were identified by proton nuclear magnetic resonance spectroscopy ( 1 H NMR), carbon nuclear magnetic resonance spectroscopy ( 13 C NMR) and high-resolution mass spectra (HRMS) data. The density at 20 °C ( d 20 ), kinematic viscosity (KV), viscosity index (VI), pour point (PP), flash point (FP), thermal and oxidative stabilities, friction-reducing and antiwear properties of gallate ester oils were evaluated. The tribological properties of gallate ester oils as lubricants for steel, copper, and aluminum tribo-pairs can be compared with those of the commercially available lubricating oil tris(2-ethylhexyl) trimellitate (Phe–3C i8 ), but their viscosity-temperature characteristics, thermal and oxidative stabilities are better than those of Phe–3C i8 . More importantly, they have much higher biodegradabilities than Phe–3C i8 . The study of the lubrication mechanism shows that the physical and/or chemical adsorption film formed by gallate ester molecules between friction pairs is the key factor for them to obtain friction-reducing and antiwear properties.
