Catalysts
With 30 years of R&D and
mass production experience our products show superior performance
in the field.
As an example of the proven past records, these our products complied with Muskie Act in the state of California.
■For gasoline engines
| Our three-way catalysts which purify carbon monoxide, hydrocarbons and NOx in exhaust gas comply with the strictest regulations though they contain only very the small amounts of precious metal. |
■For diesel engines
For all diesel engines form diesel passenger cars to light, medium, and heavy duty trucks
DPF catalysts are reducing particulate matter by the oxidation and are resistant against heat and chemical poisoning.
SCR catalysts eliminate NOx that is contained in exhaust gas by using reducing compound. Tokyo Roki introduced the world’s first SCR catalyst for a mass production vehicle. |
