Abstract
To analyze the combustion mechanism of the so-called Active Thermo-Atmosphere Combustion (ATAC) in a two-stroke S.I. engine, a measuring system to obtain images of radical luminescence in the combustion chamber was developed. The ATAC engine tested was equipped with a quartz windows as the cylinder head. The instantaneous luminescence from radical species was observed using an image intensifier with a single band pass filter for both conventional and ATAC operating conditions. At ATAC operation, emissions from OH radicals were observed before heat release began, and after that, emissions from CH were observed. It was found that the ignition was initiated over the entire area of the combustion chamber and “bulk-like” and/or “non propagating” combustion occurred during ATAC engine operation.
