Diesel Particulate Filter
Diesel Particulate Filter
The DPF diesel particulate trap is installed in the exhaust system of diesel models. Its main function is to capture the particulate matter that enters the exhaust system after diesel combustion through the filter device on the surface and inside of the device to purify the exhaust emissions. It improves the quality of vehicle exhaust emissions, reduces the harm caused by exhaust emissions to the environment, and makes vehicle exhaust emissions meet environmental protection requirements. Diesel particulate filter is a wall-flow honeycomb filter element with special structure and material, which is used in diesel exhaust purification device. Diesel particulate filters can effectively intercept and capture particulate matter (PM) and soot emitted from diesel engine exhaust, typically removing 90% or more of soot.
