Jinqu specializes in producing mufflers, SCR exhaust gas aftertreatment systems, and air reservoirs

The Fukan-DOC component is the core part of the Fukan series diesel engine exhaust aftertreatment system, and its functions and applications are as follows:

Core Role

The Fukan-DOC component serves as a critical link in the purification of diesel engine exhaust gases under China VI standards, thanks to its catalytic oxidation, temperature regulation, and NOx conversion capabilities. Working synergistically with the DPF and SCR systems, it not only meets stringent emission regulations but also helps reduce operational costs by optimizing regeneration strategies. For users, ensuring the DOC system operates efficiently over the long term hinges on properly using low-sulfur fuel and regularly inspecting the aftertreatment system.

NO-to-NO₂ conversion, assisting the SCR system

Application Scenarios

The Fuchang-DOC component is widely used in diesel engines that meet stringent emission standards such as China VI and Euro VI, including models like the Fuchang 2.8F135B and 3.8 Hongxing. These engines achieve synergistic control of PM, NOx, CO, and HC through a post-treatment technology chain comprising "DOC + DPF + SCR + ASC."

Trucks and Buses: In heavy-duty truck models like the Ouman, DOC works in tandem with DPF and SCR systems to ensure that exhaust emissions meet standards during long-distance transportation.

Non-road machinery: For example, the Foton X12 construction machinery engine meets emission standards for non-road mobile equipment through a DOC + DPF aftertreatment system.

Key Words

Fukang-DOC Component

The Fokang-DOC component is the core element of the Fokang series diesel engine exhaust aftertreatment system, playing a crucial role in the following ways: At its core, the Fokang-DOC component serves as a key link in purifying exhaust gases from China VI diesel engines by facilitating catalytic oxidation, temperature regulation, and NOx conversion. Its synergistic operation with the DPF and SCR systems not only meets stringent emission standards but also helps reduce operational costs through optimized regeneration strategies. For users, ensuring the long-term, efficient performance of the DOC requires using low-sulfur fuel correctly and regularly inspecting the aftertreatment system. Additionally, the DOC component supports NO-to-NO₂ conversion, complementing the application scenarios of SCR systems. The Fokang-DOC component is widely employed in diesel engines designed to comply with rigorous emission standards such as China VI and Euro VI, including models like the Fokang 2.8F135B and the 3.8 Hongxing. These engines utilize an advanced "DOC + DPF + SCR + ASC" aftertreatment technology chain, enabling coordinated control of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). In commercial vehicles, such as heavy-duty trucks from brands like Ouman, the DOC works seamlessly with DPF and SCR systems to ensure that exhaust emissions meet regulatory standards during long-haul transportation. For non-road machinery applications—such as the Fokang X12 construction engine—the DOC combined with DPF forms an effective aftertreatment solution tailored to the emission requirements of off-road mobile equipment.
