How Stage V Emission Regulations Will Affect Machine Manufacturing

The UK has always been a world leader when it comes to machine manufacturing. The Industrial Revolution began here after all. Unfortunately, the same technological advances that brought about the Industrial Revolution also created unprecedented amounts of air and water pollution. At the time, the effects of pollution were unknown, but as time progressed it became apparent just how damaging it can be. Since then, the European Commission has been determined to make machine manufacturing as clean as possible. To date, these efforts have been very successful. In fact, the existing regulations have already reduced the particulate matter and nitrogen oxide emissions for land machines by more than 95%. However, new evidence has proven that there is still a ways to go in order to improve the quality of the air and the health of those who breathe it. The Stage V emission regulations set to be implemented between 2019 and 2020 will introduce a new mandatory reduction of Particulate Number (PN) in addition to the continued control of Particulate Matter and Nitrogen Oxide. Recent evidence has established that the size of particles is a contributing factor to the adverse health effects associated with diesel exhaust emissions. The best and perhaps only way to mitigate these ill effects is to reduce PN count. With this in mind, and the aim to improve air quality even further, the Stage V regulations will include the following key changes: Tougher More Inclusive Standards: The new regulations will cover a number of engines which were exempt from previous versions. This includes compression ignition engines below 19kW and all engines above 560kW. Although manufacturers can emulate the technology of engines which have already met similar regulatory measures, the impact of these changes on engine subsystems such as fuel systems, air systems, and even exhaust manifolds must be carefully considered. Mandatory DPF In After-Treatment System: Another key change will be mandated Diesel Particulate Filters (DPF) in the after-treatment system. This will include both a revised particulate mass limit and a particulate number count for engines between 19kW and 560kW, which means a DPF filter will be essential for compliance. After-System Regulations for Smaller Engines: Since the new emission standards will target smaller engines than previous versions, engines under 56kW will be particularly affected. Fortunately, the existing DOC/DPF solutions used by OEMs on larger engines will be usable for engines under 56kW as well. The new regulations represent an evolution of clean technology rather than an outright revolution. Although adhering to them will require both time and capital, existing knowledge can be borrowed from on-road engines, which are no stranger to ever-expanding emission regulations. It’s worth noting that while the regulations may become a headache for some, once implemented, the EU construction machinery will be the cleanest in the world. It’s a short-term logistical pain for the long-term gain of cleaner, healthier air. Something that everyone at KTR is more than happy to get on board with.
