Laser Ignition of Combustion Engines: Development of an Ignition Laser

Abstract

The reduction of pollutant emissions and energy consumption represents a central objective in the improvement of combustion engines. In order to achieve this goal a clear optimisation of combustion processes as well as ignition mechanisms is required [1,2]. Higher compression ratios and leaner mixtures enable more efficient engine operation and lower emissions. Unfortunately, the conventional electrical spark plug reaches its physical borders and cannot fulfil such requirements. Laser ignition is a new alternative concept where the electrical spark plug is replaced by a diode - end - pumped passively Q - switched laser. The short pulses generated by this type of the laser are focused into the combustion chamber, a plasma is created and ignites the gas mixture. The main advantages of non - resonant laser ignition are the arbitrary positioning of the ignition plasma, the absence of quenching effects by electrodes as well as the feasibility of very lean mixture ignition and the reduction of nitrous oxide emissions. The development of a suitable ignition laser is essential for the realization of this innovative ignition system since there is a lack of adequate compact lasers on the market [2].
