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 is the reason why pistons are now made of aluminum, unlike ages ago when the cast iron was the favorite. Aluminum is less dense, resulting in lower weight which in turn ensures that less force is used to turn the engine parts. In increased friction translates to more heat and also quickens the rate at which wear and tear take place. This all comes down to the low performance level and increase emission of undesirable gases into the atmosphere.
As such, the engineers are always striving to obtain a combustion system with the least possible friction, and indeed, big steps have been taken towards this goal. Currently, every part of the engine is designed after a careful consideration. Naturally, the less the wear and tear effect, the more the energy available per liter of fuel consumed which in turn increases the efficiency of the vehicle in terms of mileage.
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 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.
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.
