Are We In The Right Direction Towards Engine Friction Reduction?
An automotive manufacturer who is able to produce the most fuel efficient machine is miles ahead of the rest in the industry. Proficiency in fuel consumption matters both for its economic impact and its social and environmental concerns. The activists in attempts to promote cleaner environments have been pressing the government to enact tougher laws aimed at protecting the environment from carbon emission which requires that engine friction reduction becomes the primary goal of the engine designers.
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 need to come up with a fuel efficient combustion system has pushed the specialist in this industry to the corner. Currently, consideration goes into the low tech, off-the-rack parts such as the cylinder rings, the seals, and the oil pump among other parts which are now designed to the premium rate equipment.
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 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 polymers and Teflon seals and polymers are now replacing the seals that are spring-loaded that have been used for decades. Another introduction, though not direct, is the tungsten ductile. Commonly used in space ships, and by organizations like NASA, tungsten ductile though very expensive, has found its way into sport cars. The cost and complexity has generally prevented most other industries including ordinary utility vehicles from using them. In the recent past however, some manufacturers have started rubbing this chemical in engine parts, which guards against high temperature and the effect of 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.
