Development of Hyundai ULEV system 2000-05-0297

HYUNDAI has developed ULEV(Ultra Low Emission Vehicle) system for 01MY export vehicle with 2.0 liter DOHC Engine. The system features the reduction of raw emission during cold idle phase (including start) and the improvement of L.O.T.(Light-off Time) of Closed-Coupled catalyst(CCC). Injectors with small S.M.D.(Sauter-Mean diameter) and lean warm-up control were adopted to reduce cold raw emission. L.O.T. of catalyst is shortened by adopting Sus-Pipe Exhaust manifold, retarding spark timing excessively and optimizing catalyst volume and precious metal loading.
