Since diesel engines burn fuel differently from gasoline engines, a large amount of soot is produced as a by-product of the combustion process. This wonderful, almost invisible substance can cause major health problems in the environment; DPF's job is to destroy it before it can happen. The full name of DPF is "Diesel Particulate Filter", which literally translates to "Diesel Particulate Filter", also called Diesel Particulate Capture Regenerator. It is a device that can reduce particulate matter (PM) emissions in the exhaust. During the operation of the collector, particles will accumulate in the filter. When it reaches a certain value, it will cause the engine's power and economic performance to decline. It must be removed in time to ensure that the DPF continues to work normally. So-called DPF regeneration.
