The effects of lubricating oil on friction and engine-out emissions in a light-duty 2.2L compression ignition direct injection (CIDI) engine were investigated. A matrix of test oils varying in ...

The share of friction-related costs in a car constitutes a significant part of operational expenses and can reach 20-30% of total fuel consumption, depending on driving conditions and vehicle ...

It makes sense to think that reducing the friction in an engine, transmission, axle, and transfer case, will result in more power available to the wheels. While correct in theory, several industry ...

The study of tribology, the science of friction, wear and lubrication, has increasingly benefitted from advances in molecular dynamics simulations, providing detailed atomistic insights into the ...

Given the chore of changing it every few months, the typical motorist realizes that engine oil degrades over time. Some will also notice the mysterious codes for the different grades—10W-40, 5W-30, ...

Gone are the days where greasing the track passed for a decent friction modification program. While today’s railroads control friction by the kind of lubricant used, where that lubricant is applied, ...
