Diesel filtration is crucial to proper fuel system functioning. Diesel fuel is susceptible to particulates and contaminants that impact your engine’s performance.
This article will briefly describe the importance of diesel fuel filtration. See below to learn more about how the filtration process works.
Why Is Fuel Filtered?
All the fuel passes through a filter before the injection phase in diesel fuel systems. For this reason, they are also called full-flow filters. Usually, the filtration process is carried out in multiple stages in modern diesel systems. Every fuel system uses a filtering process. However, diesel fuel purification is particularly important due to its thickness. The relatively high viscosity means diesel fuel can trap more dirt and other foreign substances in it.
Diesel engines typically filter in a two or three-stage process. The primary filter happens when fuel moves from the tank to the pump. This first step involves a coarse filter that catches substantial contaminates while smaller particles still pass through. These soils can be drained out of the pump through a plug, along with any water that collects on the bottom. Often you can check a pressure gauge to know when to clean the primary filter.
The secondary filter occurs between the supply pump and the injection pump. This more refined filter attempts to collect smaller debris before the diesel is injected into the combustion chamber. This way, fuel is made to be as pure as possible before it burns. Signs of dirty filters can include black smoke coming out of the exhaust and engine skips.
Contact a professional today if you think your diesel engine has a fuel filtration problem. Diesel fuel filters are a relatively simple way to keep your engine running smoothly, so do not neglect to replace them. Otherwise, you risk causing more severe problems in your diesel system.
