It’s crunch time for the implementation of final Tier 4 engine emission standards. Over time, understanding both what these standards are trying to achieve and whether or not they apply to a particular application has become complex. In the interests of making them a little easier to digest, CK Power has designed a visual guide (see below) to some of the most important aspects of the new EPA standards.
In the first section you’ll see how final Tier 4 emissions have changed over time. The EPA introduced diesel engine regulations back in 1996 as a way to curb emissions. In 2004, the EPA introduced Tier 4 emission standards, which began to be enforced for different engine models in 2008. By 2015 tier 4 engine requirements will be in full effect.
The second section contains a 3D graphic of how the EPA’s regulations reduce nitrogen oxides (NOx) and particulate matter (PM) with each tier of emission standards.
The final section provides a flow chart for understanding whether or not your application will require a final Tier 4 engine or final Tier 4 modifications. These regulations apply to most non-road equipment, but certain applications aren’t required to meet the current standards. Use the flow chart to see what category your application falls under.
