The DPF sensor (Differential Pressure Sensor), a crucial device installed in the exhaust system, utilizes advanced filtration technology to effectively capture over 95% of particulate mass and 99% of particulate number, significantly purifying exhaust gases. The DPF sensor not only helps reduce exhaust emissions to meet stringent environmental regulations but also improves fuel efficiency, minimizes wear caused by particulates inside the engine, and extends the engine's service life, thus achieving a dual optimization of environmental protection and performance.
