A player who can cut on fuel in the motor vehicle industry is many steps ahead of the others in terms of competition. Efficiency in fuel consumption matters a lot, not just for its economic cost, but also for the social impacts. The pressure to keep our environment clean cannot be ignored. The environmental activists and many other environmental bodies are not willing to relent from their quest to ensure that the carbon emission is at its minimum level, a factor that has greatly influenced the engineers to design engine friction reduction.
The friction and inertia are important considerations for an engineer when developing an internal combustion system, particularly for the vehicles for ordinary use. This explains why the pistons made from aluminum have replaced the ones made from cast iron that previously used. Aluminum weighs less and requires less energy to rotate. More friction means more heat, and indeed faster rate of wear and tear which in turn compromises performance.
The pressure is thus on the engineers to reduce friction to the minimum possible level, and indeed, they are not disappointing as great strides have been made in this direction. Engineers give a lot of thought to every single component that goes into the combustion system. Technically, the less friction an engine has the increased horsepower per liter it gives translating to efficiency or fuel economy.
The focus to get more fuel efficient automobile has led engineers to focus more on the low tech, off-the-shelf parts including the piston rings, the oil pump, the seals, and the bearings that are now evolving into premium rate hardware. However, these are not the only areas that can help produce more efficient combustion systems.
One area that is under consideration is the use of smaller bearings. These are coated with lead, tin, copper or compound of the same as these are considered to reduce the heat emitted. Naturally, a smaller bearing comes with less surface area which in turn means the less point of contact. The oil used is also made to be thinner. The balance shaft also comes in for the purpose of cancelling the vibration.
The other techniques used include the introduction of valves with slick coated rocks. The pistons on the other hands have smaller skirts that are coated. They are also fitted with the rings with lower tension which aids in pushing back the piston drag. Over 25 percent of friction in the combustion system results from the piston and redesigning the piston must be the primary goal for the engineers in achieving more efficient automotive.
The Teflon seals and polymers may also be used replacing the spring-loaded seals that have been used for decades. The tungsten ductile, widely used by space agency like NASA and now common in motor sport. The substance is very expense and therefore is rarely used in other industries; however, the substance is now rubbed in the engine parts to make them resistance to heat and wear and tear.
Whichever the alternative, the need for fuel economy and reduction in carbon emission remains the primary driving factor with the aim of achieving efficiency and product performance, which in turn translates to customer satisfaction.
