DPF = DIESEL PARTICULATE FILTER diesel particulate filter.
The DPF temperature sensor measures the temperature of the exhaust gas discharged from the turbocharger and provides the information needed to evaluate the DPF temperature before the exhaust gas passes through the DPF. Use this information and other data to estimate particulate accumulation and control DPF temperature to help reduce harmful gas emissions and improve fuel efficiency.
The DPF is installed in the exhaust system of diesel vehicles. It is a device that reduces particulate matter (PM) in exhaust through filtration, which helps reduce harmful gas emissions and improve fuel efficiency.
In the diesel vehicle exhaust system, the DPF system uses two temperature sensors, one located at the exit curve of the turbocharger near HO2S, and the other located at the inlet of the DPF to control the temperature of the recirculation.
