Product Application
This product is widely used in diesel vehicle exhaust aftertreatment systems for gasoline particulate filters (GPF). By measuring the pressure difference across the Diesel Particulate Filter (DPF), it monitors the DPF's working status and provides data for DPF regeneration and OBD diagnosis. Precise measurements enable on-demand DPF regeneration control to save fuel, while also controlling low-pressure exhaust gas recirculation.
