Lasers Could Replace Spark Plugs, Making Engines More Efficient

Thursday, April 21, 2011 - 14:00 in Physics & Chemistry

The spark plugs driving combustion in your car may soon be getting an optical upgrade, thanks to a team of Japanese researchers. Laser ignition systems, which are exactly what they sound like, could replace spark plugs as the primary means to ignite the fuel-air mix in engines, boosting fuel efficiency and cutting down on carbon emissions. In a conventional combustion engine, the fuel-air mix is compressed by a piston and ignited by a spark plug seated in the top of the cylinder. That spark is generated by electricity arcing between two electrodes, which is a good enough way to ignite fuel but also limiting in what kind of fuel you can burn.
