Engine filtration is always important for efficient, reliable vehicle operation, especially in diesel engines, where dirt can wreak havoc on engine quality. The oil, fuel and air filters in these engines play important roles in preventing dirt and debris from getting inside the engine and impacting operation, so it’s crucial that you prioritize high-quality filtration and change or clean filters on a regular basis to keep the system operating smoothly.

Here’s an overview of what you should know about diesel engine filters in your Corpus Christi, TX vehicle.

Keeping out the gunk

Abrasive contaminants can come from just about anywhere, and when left unchecked they could work their way into the engine assembly.

But sometimes these abrasive materials can come from seemingly innocuous sources. Fuel and lubricants, for example, can introduce contaminants into the system. If oil or fuel is contaminated with dirt or debris, that debris will make its way to the engine. In addition, water is another serious concern if it gets built up in diesel fuel. It’s not uncommon for airborne dirt or dust to enter fuel or lubrication tanks through breathers and vents. Moisture and humidity can also result in diesel fuel becoming seriously contaminated, and thus problematic when used in a diesel engine.

Each of the three main types of filters takes on a different task in protecting your diesel engine:

  • Air filters: Most diesel engines will use about 500 cubic meters of air per hour, but even a very small amount of dust can result in massive damage to some of the engine’s most important parts. Air filters need to be able to let all that air into the engine while restricting 99.99 percent of dust, at least. Over time that filter will see some dust buildup and cause blockages, which reduce the engine power and increase fuel consumption. Changing or cleaning the filter will keep the engine operating efficiently and help you avoid potentially expensive repairs.
  • Fuel filters: Diesel fuel pumps, nozzles and injectors are all designed to close tolerances of just a few microns. If abrasive contaminants get into these components, the particles could damage them and result in poor starting, inefficient operation, reduced engine power and failure of certain engine components. The fuel filter prevents contamination caused by debris in the fuel, and also acts as a water separator to prevent water contamination in diesel fuel.
  • Oil filters: Engine oil is crucial for lubricating moving parts, reducing heat in the system, improving fuel efficiency and preventing buildup of sludge and deposits. It keeps the engine oil clean by cutting down on the presence of soot and other particulates that could affect the oil. It’s important to regularly change your oil and filters so the entire system maintains efficient operation at all times.
