In order to improve the air pollution caused by the diesel engine mentioned above, many manufacturers have developed Diesel Particulate Filters (DPF) in the diesel exhaust pipe to intercept the filter in the diesel particulate filter. The method is to purify the air pollutants generated by the combustion of the diesel engine, thereby effectively purifying and improving the exhaust gas.

When the vehicle travels for a certain number of kilometers, the filter material in the diesel particulate filter will accumulate excessive air pollutants, which will gradually increase the back pressure of the diesel engine exhaust gas.
