Scientists are looking to harness light from laser beams to ignite the cylinders in combustion engines and motors.
Laser spark plugs will result in better gas mileage and fuel efficiency. This is because normal spark plugs only fire the fuel at the upper half of the cylinder resulting in a large amount of fuel going to waste. After years of running your car engine the metal terminal that sparks is slowly deteriorating.
The problems listed above can be fixed by using the new laser technology. The beam of light that is shot into the cylinder more accurately and allows more gasoline to be burned instead of being wasted. The Cars will be better on gas, give off less pollution, and provides a longer lasting engine then using a normal spark plug.
To create this technology it is actually very complex because you have to fit a high powered laser into the tiny plug that resembles a spark plug, into the combustion engine. Japanese scientists have created a solution made of strong ceramic and a material that resembles a spark plug. The Scientists have even tuned the laser to work in the smallest engine at very high temperatures and even timed it to fire at the right times.
In a country that is trying to cut back on fuel usage and head into hybrid and electric cars, the lasers to replace spark plugs would also be a big help.
