GRWA: Specializing in Catalytic Converter Technology for Efficient Vehicle Exhaust Purification

    In recent years, countries around the world have introduced stringent emission regulations to reduce pollutants from vehicle exhausts. Therefore, leveraging its exceptional technical prowess and extensive industry experience, GRWA has focused on developing and promoting efficient and eco-friendly vehicle exhaust purification technologies, particularly key components such as Catalytic Converters (DOC) and Diesel Particulate Filters (DPF).

Country-specific Emission Regulations and Standards (Partial List)

1.Europe:
    The European Union officially enacted Euro 7 emission regulations for motor vehicles on May 28, 2024. These regulations not only cover traditional internal combustion engine vehicles but also, for the first time, include electric vehicles as well as components such as brakes, tires, and batteries in emission requirements, with phased implementation starting in 2026 for different product categories.

2.China:
    China has implemented the China VI emission standard, placing strict limits on vehicle emissions. In the coming years, it is expected to release the China VII emission standard, continuing to follow the technical route of European standards.

3.United States:
    The U.S. Environmental Protection Agency (EPA) has issued three-phase greenhouse gas emission standards for heavy-duty vehicles, setting CO2 emission limits for model years 2027 to 2032 to reduce greenhouse gas emissions from these vehicles.

4.India:
    The capital of India, New Delhi, has introduced a mandatory annual inspection system for vehicle exhaust emissions, requiring all vehicles to obtain a pollution control certificate from a government-authorized testing agency before they can be driven on the road, in order to prevent winter air pollution.

"Exhaust Purifier" for Diesel Vehicles: DOC (Diesel Oxidation Catalyst)

    GRWA's DOC utilizes an advanced noble metal catalyst coating to efficiently convert carbon monoxide (CO) and hydrocarbons (HC) in engine exhaust into harmless water (H2O) and carbon dioxide (CO2) through oxidation reactions. This technology not only enhances exhaust purification efficiency but also significantly reduces gaseous pollutant emissions, providing a reliable solution for automakers.

"Exhaust Purifier" for Diesel Vehicles: DPF (Diesel Particulate Filter)

    For diesel vehicles, GRWA's Diesel Particulate Filter (DPF) is crucial for reducing particulate emissions. This filter employs wall-flow honeycomb ceramic material to effectively capture carbon particles in the exhaust, reducing particulate emissions by over 90%. Additionally, the DPF features a regeneration mechanism to ensure long-term performance and stability.
