Here on the Emissions Hub blog we talk mainly about the off-highway construction industry when it comes to emissions requirements. It is important to recognize that John Deere diesel engines play a role in several other industries, providing the right technology to get the job done, no matter what that job may entail. Although emission standards are becoming increasingly stringent across the board, standards vary depending on industry sector (for example, off-road construction versus marine). As the off-highway industry faces challenges in the coming years, it will be important to see how a variety of industries are meeting the challenge at different stages of standards implementation.
Take a look at the industries below and learn a little bit more about where they stand when it comes to emissions requirements:
- Agriculture – Modern farmers have never been more productive on their land, and the diesel engines powering their combines and tractors are a major reason why. Emissions regulations of agricultural equipment follow the same path as those in the off-highway equipment market. In fact, one of the most important milestones for new engines is how they perform in theNebraska Tractor Test Laboratory, as we showed in last August’s test of a John Deere 8335R equipped with a PowerTech PSX 9.0L engine.
- Generator Set – Generators must be able to operate at any moment for as long as necessary, yet these engines also need to meet emissions regulations. Like the off-highway market, emissions standards for the gen-set market follows a tiered approach based on engine horsepower, but the details vary for some applications and power ranges.
- Marine – Marine engines need to meet emissions regulations while also providing the legendary reliability and durability, power, and excellent fuel economy demanded by customers in this challenging industry. The big difference when it comes to marine engine emissions is the regulation levels and timeline.
