Understanding emissions compliance is no easy task, and we know there are constantly questions to be asked, and answered. Here at the Emissions Hub we want to answer some of your most frequently asked questions about the blog, and John Deere’s stance on emissions technology and compliance. Below are a few of the most frequently asked questions:
What is the Emissions Hub?
We launched The John Deere Emissions Hub in January 2011 after many of our customers started telling us that they were concerned about how new emissions requirements would affect their business. We decided to create a comprehensive online resource to provide useful and accurate information on topics such as Interim Tier 4 and Final Tier 4 off-highway emission standards, the potential impacts associated with new National Ambient Air Quality Standards (NAAQS), along with the technological innovations being used to meet the US EPA standards and potential local emissions requirements.
What exactly is Interim Tier 4 and Final Tier 4?
Interim Tier 4 and Final Tier 4 are EPA emissions standards and regulations covering off-highway vehicles and equipment. To meet Interim Tier 4 and in the future, Final Tier 4, equipment manufacturers must meet specific requirements. You can learn more about these requirements here.
How are equipment manufacturers meeting Tier 4 emissions regulations?
There are numerous ways to reduce diesel engine emissions, but the two most commonly used technologies within the off-highway industry are SCR and cooled EGR emission-reduction systems. We’ve discussed the differences between these two technologies in great depth over the last year.
What technologies does John Deere use to meet emissions regulations?
John Deere is committed to developing technical solutions that meet the business needs of customers as well as emissions requirements. For Interim Tier 4, this meant employing cooled EGR and an exhaust filter to lower NOx and PM while still meeting customer demands for improved performance and total fluid economy. Our goal is to provide the right technology, right now.
