With the beginning of 2012, we entered into the latest phase of the EPA regulations governing the diesel exhaust emissions of off-road machines. Most of you have probably heard of Tier 4. Basically, it’s a regulation that governs diesel particulate and NOx emissions. This latest regulation, referred to as Tier 4 Interim or simply Tier 4i, governs the emissions of off-road machines with engine horsepower ranges from 56 kW/75 HP to 130 kW/175 HP. To meet these regulations, advanced technologies have been incorporated into the engines, and many machine systems and components have been redesigned. We have introduced new Cat machines that meet or exceed these emissions regulations. In addition, these machines include enhancements and improvements in areas such as operation and controls, fuel efficiency, productivity, sound levels and operator comfort.
We understand that these regulations can sound a little intimidating, but you shouldn’t be worried. At Caterpillar we worked hard to make sure that your experience of purchasing, servicing, supporting, owning and operating a new machine is seamless.
If you want to learn more about Tier 4i and the Tier 4i machines, Cat.com features a page dedicated to educating our customers about Tier 4i regulations. (Click here to visit the page.) It includes information about the systems and components we’ve added to our machines. It also features links to other websites with helpful information and a contact page to allow you to get in touch with our Tier 4i experts. Cat dealers are ready to help, too.
We want to know what your experiences with Tier 4i have been so far. Have you purchased a new Tier 4i machine? Are you planning to buy a Tier 4i machine? Have you worked on any projects that mandated Tier 4i requirements on contractors? Have you avoided bidding on a project because you couldn’t meet or couldn’t understand how to meet the Tier 4i requirements?
Let us know about your Tier 4i story. We’re here to help in any way we can.
