Global energy consumption due to friction in passenger cars
TL;DR: In this article, the authors presented calculations on the global fuel energy consumption used to overcome friction in passenger cars in terms of friction in the engine, transmission, tires, and brakes.
Journal ArticleDOI
Global energy consumption due to friction in trucks and buses
TL;DR: In this paper, the authors report the global fuel energy consumption in heavy-duty road vehicles due to friction in engines, transmissions, tires, auxiliary equipment, and brakes, and estimate that the parasitic frictional losses, with braking friction excluded, are 26% of the fuel consumption.

Antiwear performance and mechanism of an oil-miscible ionic liquid as a lubricant additive.
Jun Qu,Dinesh G. Bansal,Bo Yu,Jane Y. Howe,Huimin Luo,Sheng Dai,Huaqing Li,Peter J. Blau,Bruce G. Bunting,Gregory Mordukhovich,Donald John Smolenski +10 more
TL;DR: An ionic liquid (IL) trihexyltetradecylphosphonium bis(2-ethylhexyl) phosphate has been investigated as a potential antiwear lubricant additive and a protective boundary film is believed to be responsible for the IL's antiscuffing and antiwear functionality.

Automobile Engine Tribology - Approaching the Surface
Martin Priest,C. M. Taylor +1 more
TL;DR: In this article, the authors review the nature of the surfaces encountered in the piston assembly, valve train and journal bearings of an internal combustion engine and how mathematical models of engine tribology are endeavouring to cope with the extreme complexities the incorporation of surface topography potentially brings.

Predictive wear modelling of lubricated piston rings in a diesel engine
TL;DR: In this article, a numerical model has been developed that predicts the dynamics, lubrication and wear of piston rings interactively for the first time, and the application of this new model to the piston ring pack of a diesel engine.
