Abstract

Laser ignition has been regarded in the last years as a promising ignition technique for reduction of fuel consumption and exhaust gas emissions in automotive engine vehicles, with beneficial impact on the environment. The benefits of laser ignition were discussed [1,2] and extensive research was performed to develop a viable laser-ignition device [3]. Still, due to some technical problems laser ignition seems to be more suitable for stationary gas engines [4]; thus, the ignition of an automobile engine using a laser device with the dimensions close to a classic spark plug was realized quite recently [5]. In this work we report ignition of a Renault automobile engine using high-peak power, passively Q-switched Nd:YAG/Cr4+:YAG laser devices.
