If the engine ECU senses that the DPF backpressure has increased past an acceptable threshold, an auto regeneration will occur. During the auto regeneration, the intake throttle valve limits the air flow into the engine while the injectors add additional fuel. This process increases the DPF temperature, which allows accumulated particulate to burn off.
