A Brief Explanation of Tier 4 Engines

Tier 4 regulations on diesel engines have changed the way that the portable power business operates, and for the better.  In 2011, new standards were put in place to significantly reduce emissions from off-road diesel engines, such as those in our air compressors.  Specifically, these regulations include a minimum of a 90% decrease in particulate matter from diesel engines, and also a 50% decrease in NOx emissions compared to previous levels. Simply put, this means that the diesel engines in our machines produce less pollution and provide cleaner air for your job.

Needless to say, Tier 4 engines are much more environmentally friendly than previous off-road diesel engines, which means they are safer for humans too.  According to the Environmental Protection Agency, these diesel engine regulations will prevent about 12,000 premature deaths and “hundreds of thousands fewer incidences of respiratory problems.” The amount of ozone produced by air compressors is also reduced with the regulations, which leads to a decrease in asthma attacks, damage to the lining of the lungs, and heart disease.

Tier 4 engines also run much more efficiently than previous tiers.  Because they run more efficiently, companies like Atlas Copco have been able to deliver even higher fuel efficiency rates with their new Tier 4 machines, meaning your fuel costs for running an air compressor will go down.

Overall, Tier 4 engines are better for the industry in a variety of ways.  Whether it is decreasing an air compressor’s environmental footprint, reducing health issues, or saving you money on fuel, Tier 4 engines aim to make a long term impact.  If you have any questions about Tier 4, or if you want to rent a Tier 4 unit of your own, call us today, or visit us at www.airequipmentrental.com.
