The term engine friction refers to the resistance that is created between the mechanical parts of an engine. It occurs naturally whenever two surfaces come into contact with each other such as when pistons move up and down in the cylinder or when gears turn against each other. Engine friction results in the loss of power and efficiency in the engine as the energy that is used to move the parts is converted into heat due to the frictional force.

Engine friction can be reduced by using a variety of materials, coatings, lubricants, and design features to reduce the contact between surfaces. Higher quality bearings and lubricants are used to reduce engine friction and help reduce the heat generated. The use of lower viscosity oils, such as synthetic motor oils, can also reduce engine friction. A range of high-tech coatings such as PTFE and diamond-like carbon (DLC) can be applied to engine components to reduce friction and improve efficiency. Additionally, careful design of engine components can help to reduce the contact between surfaces and thus reduce friction.

Engine friction is an unavoidable characteristic of all engines, but with the right materials and design considerations, it can be managed and minimized to improve engine efficiency and performance.
