The piston skirt and pin account for about 17 percent of the frictional loss in a combustion engine as they are the most difficult to keep lubricated and have the largest contact surfaces. OE ...

Heat is also a byproduct of friction. Think about rubbing your hands together to warm them up. The faster you rub your hands together, the hotter they get. Now think about the pistons in your ...

Examples of the main engine components on which vehicle manufacturers and suppliers are working to reduce friction components include the following (Truett 2013): Smaller, low friction bearings: ...

If a new car engine is to run „smoothly," first it has to be properly run in: drivers should avoid quick acceleration and permanent short trips during the first 1000 kilometers, for instance. Why is ...

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, ...

If asked what you wanted for piston rings in your engine build, would you know how to answer? Piston rings have the most important job in your engine. We will get arguments on this one because there ...

You already know that an oil change is a key part of making sure your engine performs. Even the best engine oils break down over time. Additives are used up, particulates and soot enter the mix, and ...

Friction is responsible for about twenty percent of the world energy consumption. The main reason for this is that frictional forces slow down the motion of surfaces in contact: think of the moving ...
