Replacing medium duty truck parts is inevitable. Especially when dealing with a Diesel Particulate Filter (DPF). It's a part with an efficiency that depends on how many times it gets cleaned. Your goal is to find a way to prolong the life of machine parts and find a way to save on replacement parts.
When faced with options of cleaning, replacing or deleting a DPF or even an exhaust gas recirculation valve (EGR), the choice can be a difficult one. Let's take a look at DPF's and EGR's to consider the best options for efficiency.
What is a DPF?
A DPF is a medium duty truck part in the exhaust that collects soot to keep the air clean. It captures particles in a mesh net and reduces harmful emissions.
If you know all about your DPF, you have probably already had it cleaned. You should know that with each cleaning of a DPF, it reduces its “cleaning efficiency” by ten. By the third cleaning, your DPF operates no better than 70% efficiency and could be as low as 50%.
This means that while cleaning the part will save you money for a while the part will need to be replaced at some point. For that reason, when purchasing medium duty truck parts reconsider buying refurbished parts. A DPF that has been used will be behind the curve because it has already been cleaned. So your refurbished part already has a reduced efficiency before you even start.
The DPF isn't the only medium duty truck part that can be cleaned to prolong its life, before needing a replacement. Another part that works closely with the DPF is the EGR.
What is an EGR?
An exhaust gas recirculation valve also reduces emissions. It works by recirculating part of the exhaust gas back to the engine's cylinders. This prevents DPF failure because it sends gases away from the engine, making it run more efficiently. The main goal of an EGR is to reduce the amount of nitrous oxide running through the exhaust system.
The function of this part can cause it to become clogged and get stuck open or closed. When dealing with a clogged EGR, removing it, cleaning it, or cleaning sprays are an option, but the best thing to do is replace it.
What is Deleting a DPF or EGR?
Deleting a DPF or EGR is simply removing the part. Claims of increased efficiency or power have surfaced, but these claims are empty promises. Removing either part could save you money in the start because you won't have to buy a new one. It can cost you more down the line. Beware when considering this option because removing the DPF isn't strictly legal and you will be looking at some sort of offense.
Clean, Replace, or Delete
At one point or another you will clean one of the two medium duty truck parts we discussed. Cleaning the DPF or EGR will save you time, but to be sure you have the most reliable truck parts you will need a replacement. No matter what you choose to do and when you choose to do it, go for the most reliable option. Be cautions of the idea to remove any parts. With reliable truck parts online save yourself the time and stress and do it right the first time. Give your trucks the treatment they deserve.
