    Chemcial Species Tomography (CST) can be used to provide information on the spatial distribution of a target species by reconstruction from multiple independent optical absorption measurements taken in the measurement space. In this paper, we describe how CST can be used to capture the spatial and temporal distribution of the fuel-vapour mixture within an internal combustion engine, thereby providing invaluable data to engine designers in their quest for reduced emissions and improved fuel economy. We further report on the first application of CST to a standard, multi-cylinder production engine, which involved the design and fabrication of a custom OPtical Access Layer (OPAL), which provided 27 independent, collimated optical channels in one cylinder of a 4 cylinder, 2.0 litre gasoline engine. © 2006 Optical Society of America.
