EU Stage V standards

EU Stage IV/U.S. EPA Tier 4 Final are the latest emissions standards in force and we have developed our engines to meet them. But what does the future hold? When will EU Stage V come into force, what will it require and is there a similar move to develop a U.S. EPA Tier 5?

With Stage IV emissions standards now in force for engines in the 56-560 kW range, you might now be thinking about the future; is a Stage V on the cards? And for the U.S. market, will there be a Tier 5 emissions standard?

At present, there are no plans in the U.S. to supersede Tier 4 Final but EU member states are considering proposed additional standards that would become Stage V in 2019 or 2020.

The next stage of EU emission standards comes into force in 2019 and 2020 for non-road diesel engines across the power spectrum. Machines for construction, agriculture, materials handling, industrial use and generators will all be in scope of these new standards.

The standards will continue the path towards reduction of particulate and NOx emissions. The main difference with Stage V is that for the first time there will be a limit on the number of particulates. In practice, this will drive the adoption of diesel particulate filters (DPFs) for engines in this power range.
