Product Categories

  • Installed in universal small  gasoline engine machinery exhaust systems that reduce emissions of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx)  through a reduction or oxidation reaction with the catalyst.

  • Installed in the exhaust system of motorcycles, which can reduce the emissions of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the exhaust system through the reduction or oxidation reaction by catalysts.
    Catalyst principle: increase the activity of CO, HC and NOx ,  promote a certain oxidation-reduction chemical reaction; CO is oxidized to colorless, non-toxic carbon dioxide gas at high temperature; HC compounds are oxidized to water (H2O) and carbon dioxide; NOx is reduced to nitrogen and oxygen

  • It is the core of the catalytic converter installed in the exhaust system of gasoline vehicles to reduce the emission of pollutants [carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx)] through catalytic redox reaction.
    It is the catalyst used in the three-way catalytic converter of automobile exhaust gas, which has high activity, high selectivity, high thermal stability, good physical properties, and can simultaneously clean the exhaust gas of CO, HC and NOx and other harmful substances.

  • Installed in the exhaust system of diesel engine, which can reduce the emissions of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the exhaust system through the reduction or oxidation reaction of catalysts.
    Catalyst principle: increase the activity of CO, HC and NOx gases, to promote a certain oxidation-reduction chemical reaction; CO is oxidized to colorless, non-toxic carbon dioxide gas at a high temperature ; HC compound is oxidized to water (H2O) and carbon dioxide; NOx is reducted to nitrogen and oxygen.

  • Excellent catalyst performance, wide triple effect window, high conversion efficiency
    Excellent temperature characteristics, air velocity characteristics, air-fuel ratio characteristics
    Targeted materials and technology, lower precious metal content of catalyst, higher cost performance
    Uniform and firm catalyst coating, no rusting and no peeling
    Excellent durability performance to meet CARB and above emission standards and durability requirements

  • The EGR cooling system is a device set up to reduce NOx emissions from vehicle exhaust gases and is a key component of the exhaust gas recirculation system. Under engine running conditions, a small amount of exhaust gas is reintroduced into the intake valve. The exhaust gas is a non-combustible gas (without fuel and oxidizer), which does not participate in combustion in the combustion chamber and reduces the combustion temperature and pressure by absorbing part of the heat generated by combustion in order to reduce the amount of nitrogen oxide production.
    The company has developed various structures of EGR coolers, including tube, plate and fin type, with excellent welding quality and high heat transfer efficiency to meet the needs of various models.

  • Metal carriers, especially metal honeycomb carriers, are widely used in catalysts, especially for small gasoline and diesel engines, because of their excellent heat transfer performance, large internal surface area, excellent temperature and vibration resistance and convenient welding conditions.
    We have developed various specifications and structures of metal honeycomb carriers to meet the requirements of various models.
