LASER SYSTEM FOR IGNITION OF ENGINE

Nowadays, combustion engines and other combustion processes play an overwhelming and important role in everyday life . study of ignition of combustion processes is of great importance. Spark plugs are well suited for such tasks but suffer from disadvantages, like erosion of electrodes or restricted positioning possibilities. Over the conventional ignition systems, ignition of combustible materials by means of high power laser pulses could be beneficial. the main goal is the creation of a laser system which meets the engine-specific requirements. Basically, it is possible to ignite mixtures with different types of lasers. The laser ignition system has a laser transmitter with a fiber-optic cable. It shoots the laser beam to a focusing lens that would consume a much smaller space than current spark plugs. The lenses focus the beams into an intense pinpoint of light, and when the fuel is injected into the engine, the laser is fired and produces enough energy (heat) to ignite the fuel. Laser igniters able to combust the fuel with lean air-fuel mixture as compare to conventional spark plug, which helps to lower down the Nox emission and gives better fuel efficiency.
