"CSD (Combustion Stabilizing Device)" is being
developed to meet SULEV/ULEV (Super-Ultra Low Emission Vehicle/Ultra Low
Emission Vehicle) emission standards on small to large displacement internal
combustion engines. To reduce automotive emissions to SULEV standards it is
necessary to start the engine in a stoichiometric, or lean, state (or go to a
stoichiometric state quickly after start.) In order to achieve stoichiometric
cold starts, vaporized fuel is needed, which is supplied by the CSD.
