Abstract

A comparative study of ignition realized by a classical spark plug and by a Nd:YAG laser in 12% methane-air mixture was performed. Various parameters of the ignition, such as the peak pressure, the pressure building time, or the speed propagation of the flame front were recorded at various initial filling pressure of the combustion chamber, or function of the laser pulse energy. Advantages of ignition by laser in comparison with classical ignition by an electrical spark plug are discussed..
