Catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants such as CO, HC, NOX and PM in exhaust gas from an internal combustion engine fueled by either gasoline or diesel into harmless CO2, N2 and H2O with a high conversion rate by catalyzing a redox reaction (an oxidation and a reduction reaction).

Wire mesh and metal honeycomb catalysts are widely applied on small off-road engines. Thanks to the advantages of small volume and low price, they are suitable for two-stroke and four-stroke small lawnmower，chainsaw, brushcutter，generator and so on. Our advanced technology and experienced R&D team guarantee a good coating adhesion performance and high thermal shock resistance.

An activated carbon canister is used to capture hydrocarbon vapor emissions from the fuel tank as part of an evaporative emission control system (EVAP). When the engine is running these stored hydrocarbons can be purged by opening a valve to the intake system and reversing the flow through the carbon canister allowing the engine to consume the hydrocarbon vapors by combustion.
