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.
This explains the need to use aluminum over cast iron in the manufacture of pistons. Aluminum being less dense means less weight which in turn ensures that less energy is require for rotating parts of the combustion system. In the same time, less weight significantly cut down on the rate of wear and tear and heat emitted which in turn translates to efficiency and less carbon discharge to the surrounding environment.
The need to eliminate engine friction gets even more important as the engineers are getting smarter. Today, a lot of consideration is given in every component that goes into the manufacturing of the engine, the lubricants used, and the fuel that goes in. The lower the friction, the more the horsepower per liter of displacement an automotive have.
The competition in no longer on appearance, or cost, fuel efficiency has now developed to be the primary area of completion in this industry. As of now, the focus is mainly on the low tech parts considered to be off-the- rack components such as the oil pump, the cylinder rings, and the seals which are now developed into top of the notch hardware.
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.
In addition to the improvement above, the technicians are also looking at introducing valves that have rocks fitted with slick coating and rollers. The pistons can also be made so that they have small coated skirts in addition to fitting with rings that give low tension which helps to push back against the piston drag. The pistons are known to be responsible for up to twenty five percent of all the energy loss from friction and must thus be targeted in this modification.
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.
Regardless of the method used the need to improve efficiency and reduced carbon emission is the main drivers that keep engineers sleepless with the hope of achieving the most user friendly and environmental friendly vehicles for the future generation.
