Abstract
This study examines the laser ignition of methane-air mixtures in a Rapid Compression Machine (RCM). The lean limit and the minimum ignition energy (MIE) were investigated in the engine-like conditions provided by the RCM. A lean limit of ϕ90=0.47 was found experimentally for a laser spark energy of 5 mJ (corresponding to 90% combustion efficiency). MIE was found to exhibit a stochastic behavior and results can only be interpreted statistically. The MIE study was conducted at an equivalence ratio of ϕ=0.4 yielding an MIE (90% probability) of MIE90=7.2 mJ.
