Gasoline engine catalysts

With the widespread of hybrid Electric vehicles (HEV) and gasoline vehicles equipped with an idling stop function, the usage of gasoline engines is becoming more diverse than before. Therefore, 3-way catalysts for gasoline vehicles are required to have the ability to purify harmful substances such as nitrogen oxides (NOx) even at various temperatures and oxygen concentrations. There is also an urgent need to improve technology to suppress emissions of ultra-fine particulate matter (PM) in order to respond to stricter regulations in each country. Cataler is actively working on these issues, and has earned high acclaim and deep trust from automobile manufacturers.
