In the automobile industry, the player who can save more fuel is already an edge above the others. The fuel economy is very critical, considering that the cost of fuel cost has been steadily rising. Other than just saving on fuel, there are several other potential benefits associated with engine friction reduction. These range from a smooth ride to a long lasting engine. In addition to these economic factors, there are a number of social-political considerations such as environmental impacts which puts into account the energy consumption and emissions.
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.
A smaller bearing coated with other metals like copper, lead, tin or their compounds for instance is considered to better in the reduction of friction. The smaller bearings technically mean the smaller surface area. This together with thinner oil gives rise to efficiency. In addition to this, the balance shaft is also used to cancel the vibration.
The other areas that the scientists are pursuing to produce more fuel efficient automobiles include the introduction of valves rock that have slick coating and rollers. The other option is the use of pistons that have small coated skirt, and fitted with rings that produce low tension. These help push back against the piston drag. This is specifically important since the pistons contribute up to a quarter of all energy loss resulting from friction.
The other available alternatives include the use of polymer and Teflon seals. Many motor vehicle manufacturers are now opting for seals over the old-styled spring-loaded seals that previously used. This is just another example of the technology the engineers are considering. Tungsten ductile, a chemical compound commonly used in the space agency NASA as a lubricant, and later widely used in auto racing has not been largely exploited by other ordinary vehicles largely due to its cost and complexity. However, some companies are now rubbing it on the engine parts to give a wear and heat resistant surface.
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.
