Spark Plugs To Make Way for Lasers

Spark plugs have been around for 150 years in automobiles to power the internal combustion of engines. Laser on an engine cylinder head Spark plugs function by emitting small, high-voltage electrical sparks across a gap between two metal electrodes. Taira also claims that the lasers can focus their beams directly into the air-fuel mixture and the flame front will expand more symmetrically which is up to three times faster than spark plugs. Also according to Taira, conventional spark plugs pose a barrier to improving fuel economy and reducing emissions of nitrogen oxides, a key component of smog. Taira’s team is working with a spark plug manufacturing company called DENSO Corporation which is a part of the Toyota Group and although highly promising, these laser systems have not yet been installed in automobiles.
