Does China VIa Have a Particulate Filter?

[AdrianaMarie]

China VIa vehicles are equipped with particulate filters, and the type of filter varies depending on the fuel type. Diesel vehicles are equipped with DPF (Diesel Particulate Filters), while gasoline vehicles are fitted with GPF (Gasoline Particulate Filters). Here is some information about particulate filters: 1. The filtration mechanism of DPF in diesel engines and GPF in gasoline engines is essentially the same. Both use wall-flow filters, where exhaust gases are forced through the porous walls of a honeycomb ceramic filter by alternately blocking the channels. Particulates are captured and filtered through four mechanisms: diffusion, interception, gravity, and inertia. 2. However, there are still many differences between GPF and DPF. The main distinction lies in the substantial differences between gasoline and diesel engine exhaust. Compared to modern light-duty diesel engines, gasoline engines emit approximately 10-30 times fewer particulate emissions. This difference drives the selection of optimal filtration technologies.
