What is the Role of Diesel Particulate Filter

Diesel particulate filter (DPF) is said to considered as one of the most in-demand engine parts for heavy-duty vehicles. As much as we make sure that our vehicles look great and good on the outside, we also needed to ensure that its engine are also performing great from the inside.

With that said, it is important that you must maintain a regular cleaning of your filters, or replace them with a good and new DPF if it’s no longer performing well. This entirely affects the performance of your vehicle, if it’s left unattended it might cause serious trouble not only to your vehicle but to you who use it as well.

To fully understand this, a DPF is a filtration system designed to reduce PM, including soot from the exhaust of a diesel engine. A series of alternately blocked channels forces the exhaust gas to flow through the channel walls where the particulates are physically captured in the filter.

Many rental generator applications have low load factors or utilize oversized equipment because of limited information on the customer’s load profile. During a low load operation, a DPF will accumulate PM due to low exhaust temperatures resulting in increased back pressure on the engine. As backpressure increases, eventually, the particulates must be removed from the DPF through a process known as regeneration.

Exhaust temperatures are increased to above 575°F to facilitate regeneration of the DPF. Manufacturers differ on the method of achieving these elevated exhaust temperatures.

But we get it, with a lot of choices to choose from in today’s market, it is for sure to choose one immediately. But today, we will give you a few good reasons why you should invest in Caterpillar engine DPF.
