Ford engines division is currently testing a new laser ignition system for implementation on their high end cars in a few model years. This system is designed to increase the efficiency of the automotive engines ignition system. Since laser beams can be split into multiple beams, it would be possible for the laser ignition system to create multiple points of ignition.
Increasing the number of ignition points also enables the engine to start easier in cold and damp conditions, as well as providing for an overall more complete combustion of the fuel mixture, increasing fuel efficiencies under any driving condition.
When you think of it, it is about time the spark plug was redesigned for better efficiency. It is one of the parts of an engine you don’t hear much about regarding new technologies.
Here is what Dr Tom Shenton, a researcher at Liverpool University leading the project, said:
“Lasers can be focused and split into multiple beams to give multiple ignition points, which means it can give a far better chance of ignition. This can really improve the performance of the engine when it is cold, as this is the time when around 80 per cent of the exhaust emissions are produced and the engine is at is least efficient.
“The laser also produces more stable combustion so you need to put less fuel into the cylinder.â€
In the new laser ignition system, the car battery powers a laser which is directed into the engine cylinders by fiber optics and specialized lenses. Researchers in Liverpool claim that the laser will also require less power than traditional spark plugs, even though the laser system will need to fire more than 50 times per second to produce 3000 RPM.
It seems to be an interesting technology, one of the few thing that has not been redesigned or improved much over the years are conventional sparks plugs. The idea of experimentation with lasers proves how serious auto manufacturers are about meeting and beating future emission standards.
Competition is a good thing in my opinion, it forces the best companies to compete against each other in order to stay on top of, or invent new technologies. The companies that try the hardest and develop good working technologies win. The companies that rest on their laurels fade away into the sea eventually.
We all need to evaluate which companies put out the effort to improve our environment, and do it right. When it comes down to the actuality that you may need a replacement engine someday (with spark plugs) GotEngines.com has the competitive instincts to try harder than any other engine supply companies to fulfill your engine needs with great values on all sorts of remanufactured replacement engines.
Trust me, who to buy an engine for sale from is hard to determine. Since our goal at GotEngines.com is to be the best engine suppliers in North America, we have to constantly research and update the best methods of procuring and selling the finest remanufactured replacement motors on the market. Guaranteed.
