DPF Exploration

With the increasingly strict emission standards, issues such as truck torque restrictions and stalling have gradually emerged, and the term DPF has also gradually entered the vision of cardholders. So, what is DPF and how should we respond when it encounters problems? Next, we will delve into the connotation and countermeasures of DPF.

In modern truck technology, particulate matter filters, also known as DPF, have become standard equipment for many vehicle models. It is similar to the filter cotton in familiar vacuum cleaners, mainly responsible for capturing particulate matter such as soot and carbon powder in engine exhaust.

As cigarette ash and carbon powder accumulate in the DPF, the vehicle needs to perform regular DPF regeneration operations. This regeneration process can be passive regeneration during driving or active regeneration after parking. Its core is to completely burn the accumulated carbon powder through high temperature, convert it into carbon dioxide, and discharge it outside the car. If the regeneration process is not thorough, the DPF may gradually clog, leading to vehicle speed limit, torque limit, and even insufficient engine power due to poor exhaust. Therefore, the speed and torque limit issues of vehicles are often closely related to the working status of DPF.
