Henceforth, the 3.0 EcoDiesel exhaust system looks like this: downpipe > DOC > SCR > DPF > muffler. So all of these different pieces of emissions equipment sit within the exhaust. And then you reach the DPF system which is actually integrated into the same pipe as SCR. Next is SCR, or selective cat reduction, which is the equipment that uses DEF fluid to burn nitrous oxide. It functions like a normal catalytic converter, but for diesel gases. The DOC, or diesel oxidation catalyst, is the first exhaust emissions equipment. All of this equipment sits within the exhaust with the exception of the EGR system which occurs pre-exhaust. The 3.0 EcoDiesel for example also has SCR, DOC, DEF, and EGR systems. The DPF system however is slightly more complicated in that it is incorporated with a number of other emissions equipment. They are trapped into a catch can and then are further burned down via regeneration cycles. The DPF filter is in the exhaust system and captures these particulates before they escape to the atmosphere. When diesel fuel burns a byproduct is small chemical particulates that are bad for both the environment and human health (when inhaled). It is essentially similar to a traditional catalytic converter but its job is to capture diesel particulates. What is the EcoDiesel DPF?ĭPF stands for diesel particulate filter. This guide is going to discuss the EcoDiesel emissions equipment, the pros and cons of deleting the DPF system, and how-to delete the DPF. And in addition to reliability issues, the DPF system also restricts performance potential.ĭeleting the EcoDiesel DPF system in Ram 1500’s and Jeep Grand Cherokee is popular for both performance and reliability purposes. Outside of the EGR cooler, the DPF system is prone to clogging and both of these items are very expensive to replace without warranty. While the emissions systems on the EcoDiesel are good for reducing emissions, they are bad for reliability and maintenance costs. EGR cooler failure is among one of the most common 3.0 EcoDiesel problems. However, the biggest drawback to using a non-Cummins diesel is that the EcoDiesel has disastrous emissions systems. While the engine is different than the 6.7 Cummins, the emissions systems are virtually the same. Released in 2014, it’s a 3.0L V6 turbo-diesel and is offered in half-ton Ram 1500 trucks and Jeeps. Despite Dodge’s larger diesel engines being manufactured by Cummins, they took another route for the 3.0 EcoDiesel.
