How Does an Air Filter Affect Engine Performance?
As experts in all types of diesel equipment filters, Fleetguard understands just how vital engine air filters are to maintaining the overall health of your equipment.
Performing regular check-ups and using clean engine air filter technology are simple and effective. They ensure that the lifespan and efficiency of your equipment are maximized, saving you money in the long run. Maintaining high-quality engine air filtration is critical to protect your engine from various forms of debris like dirt, dust, sand, mud, small rocks, and so on.
When properly installed and maintained, engine air filters protect your investment and ensure:
- Consistent operation
- Proper horsepower
- Efficient fuel economy
- Reduced emissions levels
However, insufficient maintenance or poorly designed filtration can quickly lead to expensive damage. In this article we’ll discuss some of the most common bad air intake symptoms and the effects of a dirty air filter on engine performance.
What Are the Symptoms of a Dirty Air Filter?
In this section, we’ll review a few symptoms of bad air filter problems, specifically related to engine air filters, to help you identify if your engine air filter is negatively affecting your machinery’s functionality and needs to be replaced.
- Know the difference between a dirty air filter vs a clean air filter. Of course, any air filter will appear to be somewhat dirty; that just means it’s getting the job done. With that said, how dirty should an air filter look? A dirty engine air filter will be either completely dark brown or black. If this is the case, it’s time to install a replacement.
- Monitor issues with mileage and fuel efficiency. If your engine air filter is too dirty or is malfunctioning, you will experience a noticeable decrease in fuel efficiency. Installing a clean air filter will ensure the engine’s airflow is unobstructed, increasing fuel efficiency.
- Don’t ignore dark exhaust and a strong fuel smell. In addition to monitoring the engine’s air intake, an engine’s output will indicate problems with the air filter. If potent fuel smells and dark exhaust are coming from the engine, then it’s likely that the air filter is experiencing issues and needs to be replaced.
- Check for decreases in horsepower. A dirty engine air filter will often lead to a decrease in power and effectiveness of the equipment. If the machinery is having issues accelerating or is operating slowly, this likely means that the air filter is limiting the equipment's air intake, diminishing its overall performance.
- Listen to your engine light. A machine’s check engine light can come on for many reasons, including issues with the engine air filter. As soon as the check engine light comes on, it’s important to stop what you are doing and begin to investigate. Specific issues that can trigger this response differ depending on the equipment type, but reviewing the air filter will let you know if the trigger for the check engine light is air intake problems.
In addition to being aware of these warning signs, exploring technology and predictive maintenance take the guesswork out of monitoring your air filter’s performance is helpful. Fleetguard’s intelligent FleetguardFITTM condition-based monitoring system makes it easy to review your filter’s performance. Using data analytics and advanced sensing technology, FleetguardFIT provides real-time status updates that tell you exactly when maintenance is needed.
What Kind of Effects Can a Dirty Air Filter Have on Engine Performance?
Can a dirty air filter ruin your engine? In short, yes, it can. If a dirty engine air filter is not replaced, problems will only intensify. Debris will continue to clog and reduce the air flow, increasing inefficiencies. Beyond general wear and tear, continuing to use a dirty air filter can lead to:
- Hindrance of machine operation
- Devastating equipment damage
- Equipment breakdowns
- Expensive repair costs
- Missed deadlines
Adhering to regular maintenance schedules and replacing dirty or damaged air filters will protect your engine, improve the lifespan of your equipment, and maximize your return on investment. In short, paying for an engine air filter replacement is always more affordable than buying a new piece of machinery. For example, Fleetguard’s NanoNetⓇ air filters offer 30% lower expenditure and 99.99% efficiency, giving managers and operators more bang for their buck.
