Hyundai makes car care easy by innovating solutions that go Beyond Mobility. Here’s a look at how effortless it is to clean your diesel particulate filter yo In certain circumstances it is possible or even necessary to do a forced regeneration of the DPF, but this is a very severe process and carries risks. The execution of a forced regeneration causes greater stress on the engine than an automated regeneration. The oil gets very hot and this causes premature degradation. Active = fuel is injected into the exhaust stroke strictly for the purpose of increasing exhaust gas temperatures (EGT's) in order to get to the temperature necessary to burn the soot out of the diesel particulate filter (DPF). Your truck will regenerate (active) when the DPF soot level reaches 65%. This will likely occur every 100-300 miles. Apr 25, 2018. #1. I am using the BlueDriver OBD II scanner tool for live data and this it shows the DPF regen status, a trigger percentage (A percentage until next regen), exhaust temp and def tank level. I have noticed that the regeneration status shows active once exhaust temp is steady at 900 degree but when I come to a stop it shows inactive. DPF REGENERATION. DPF regeneration is the process of burning off accumulated soot from the DPF to prevent it from clogging and reducing the engine’s performance. When the soot builds up, the DPF’s backpressure increases, which can lead to a loss of power and fuel efficiency. To regenerate the DPF, three methods are available: passive An illuminated DPF light will cause an MOT failure. Since part of an MOT test is to check that vehicles comply to environmental standards, a faulty or missing DPF will cause an immediate failure. What to do if the DPF light comes on. If your DPF light turns on, the first thing you should do is attempt to initiate a DPF regeneration cycle. JmezRg. inadequate filter regeneration will cause a DPF to require more frequent cleaning. Diagnostics should be performed to identify the cause for more frequent cleaning intervals. A backpressure monitoring system should always be used with a DPF and periodic inspection of the monitoring system should be performed to confirm proper operation. The DPF is a crucial component of the tractor’s emissions control system, and regular cleaning ensures optimal performance. Follow the manufacturer’s guidelines on cleaning frequency and procedures. 2. Use high-quality diesel fuel. Low-quality or contaminated fuel can lead to increased carbon buildup in the DPF, hindering regeneration. The first two indicators mean that the engine control module has detected soot buildup in the DPF and is initiating a regeneration process. Don’t shut off the engine until the lights clear. The third symbol shows a failed regeneration attempt, and the fourth asks for immediate intervention. In both cases, you would need to do parked regens. As for the active regeneration, this occurs when the exhaust is not hot enough to eliminate the soot that has built up. Thus, the engine lets out a bit of fuel right into the exhaust stream. This boosts the temperatures that help to burn the fuel and soot away. Unfortunately, it may happen that the active and passive regens will fail. If the car starts a DPF regeneration, extend your journey if need be until it has finished the job (takes around 5-10 mins of driving, in my Alfa at least), and give it some beans to help it out.
