Diesel Particulate Filter (DPF) Catalyst

The Diesel Particulate Filter (DPF) is a physical filtration device whose core function is to capture soot particles and soluble organic fractions from exhaust gas through a forced physical process, thereby significantly reducing the number and mass of particulate matter. The role of the DPF catalyst is not to directly purify the gas, but to lower the oxidation temperature of the trapped particulate matter, enabling the DPF’s self-regeneration. The DPF operates as a “capture first, then burn” physical filtration system. The catalyst’s core mission is not gas purification, but to facilitate the “burning” process. By means of a precious metal coating or fuel additives, it substantially reduces the oxidation temperature of soot, enabling both passive and efficient active regeneration of the DPF, ensuring its long-term and stable operation. This technology is critical for addressing the problem of “black smoke” emissions from diesel vehicles. Together with the DOC and SCR systems, the DPF forms the core after-treatment lineup of modern clean diesel engines.

Focus on three-way catalytic carrier coating

Founded in July 2024, Longyou Shuochun New Material Technology Co., Ltd. is a high-tech enterprise specializing in the coating and sales of three-way catalytic converters. It is deeply engaged in the field of new materials.

The company always keeps an eye on the industry frontier, actively learns from and draws on the advanced formulas and mature technologies of domestic and foreign counterparts. Through in-depth research and localization of mainstream formulas, it accurately adjusts the proportion of raw materials such as rare earths, precious metals and non-precious metals, so as to ensure that the coated carriers produced have stable catalytic activity and reliable performance.

The company's products cover a variety of specifications and models, and its products and technologies are applicable to automobiles, motorcycles, general-purpose engines, construction machinery, marine power, generator sets, agricultural machinery and other fields.
 
In the future, the company will continue to learn advanced industry experience, optimize production and services, and contribute to the realization of carbon peaking and carbon neutrality goals in China and around the world.
