The Cummins 6.7-liter engine was introduced in 2007 to replace the 5.9-liter engine. The 6.7L Cummins is an inline six-cylinder diesel engine that produces up to 350 horsepower and 650 lb-ft of torque. It features a high-pressure common rail fuel injection, a variable geometry turbocharger, and an exhaust brake. The 6.7 Cummins is used in a variety of applications, including Dodge Ram 2500 and 3500 trucks, as well as some Jeep Grand Cherokees.
6.7 Cummins DPF Delete Problems
The 6.7 Cummins engine is no stranger to problems and has been the subject of multiple recalls and service campaigns. One of the most common issues with the 6.7L Cummins is the failure of the diesel particulate filter (DPF). The DPF is a device that captures and filters soot from the exhaust gas. It is required by law in order to meet emissions standards.
The DPF can become clogged with soot, which can cause a number of problems. The most common symptom of a clogged DPF is reduced power and fuel economy. The engine may also go into “limp mode”, where it will run at a reduced power output in order to protect the engine from damage.
So, you may find the following problems with your 6.7 Cummins:
1. Reduced Power and Fuel Economy
You may notice that your truck doesn’t have the same power as it used to. This is because the DPF is restricting exhaust flow and causing the engine to run less efficiently. You may also see a decrease in fuel economy.
2. Check Engine Light
The check engine light may come on due to a problem with the DPF. If the light is accompanied by the word “regen”, it means that the DPF is due for a regeneration cycle. During this cycle, the engine will run at a higher RPM in order to burn off the soot that has accumulated in the DPF.
3. Exhaust fumes
If you notice an increase in exhaust fumes, it could be an indication that the DPF is clogged.
4. Engine “limp mode”
If your engine goes into limp mode, it means that the DPF is severely clogged and the engine is running at a reduced power output in order to protect itself from damage.
5. DPF Warning Light on Dash
The DPF warning light is a yellow triangle with an exclamation point in the center. This light will come on when the DPF needs to be cleaned or replaced.
If you are experiencing any of these problems, it is important to have your truck checked by a qualified mechanic as soon as possible. Attempting to drive with a clogged DPF can cause serious damage to your engine.
How to Deal with a Clogged DPF?
A clogged DPF can eventually lead to engine failure if it is not addressed. One way to address a clogged DPF is to have it cleaned or replaced. However, this can be an expensive proposition.
Another way to avoid the problems associated with the DPF is to delete it. DPF deletion is the removal of the DPF filter from the exhaust system. This can be done by removing the DPF sensor and replacing it with a dummy sensor, or by installing a DPF delete kit.
6.7 Cummins DPF Delete Kit
DPF Cummins delete kits are available that disable the DPF system and allow the engine to run without it. This is not legal in all jurisdictions, so be sure to check the laws in your area before doing a DPF delete.
DPF delete kits are designed to bypass the DPF filter and allow the exhaust to flow freely. This can increase horsepower and fuel economy, as well as reduce wear on the engine. It is important to note that DPF delete kits are not legal in all states, so be sure to check your local laws before installing one.
Whether or not to delete the DPF is a personal decision that should be based on how the vehicle will be used. If the vehicle will mostly be driven on short trips or in stop-and-go traffic, then it may make sense to delete the DPF. However, if the vehicle will be driven on long trips or highways, then it may be better to keep the DPF and deal with the occasional clogging issue.
