On track for EU Stage V emission standards

EU Stage V standards

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.

Mobile diesel generators also in scope

As well as traditional mobile equipment such as tractors, wheeled loaders and excavators, Stage V standards will apply to mobile generators. These obviously include generators which are on wheeled trailers, but also those which are designed to be moved to different work locations such as those commonly used by equipment rental companies.

Diesel generators that are permanently installed in one location and not intended to be moved are not in scope of Stage V, though may be in scope of other regulations. Permanently installed means bolted or otherwise fixed to a foundation or some other constraint.

Transition schemes

There will be no flexibility scheme available during implementation of the Stage V emission standards. Original Equipment Manufacturers (OEMs) will have 18 months to consume inventory of engines of the previous emissions type into their machines and a further six months to place them in the market. Independent OEMs with a total production of non-road mobile machinery equipped with engines of less than 100 units a year, will have an additional year to build and sell their machines.  OEMs will need to satisfy themselves that they are eligible for this additional allowance.

Technology requirements?

Due to the different emissions levels, machine technologies and customer priorities through the power range, whilst the use of a DPF is a key element, there is no single ‘best technology recipe’ to meet the Stage V emission standards.

One of the most impacted power ranges will be engines between 19 and 37 kW – many of which will require technology such as common rail fuel systems and exhaust aftertreatment for the first time. For most OEMs, however, adapting their equipment to Stage V technologies will be a lower level of change than previous emissions stages.

Why is Perkins the right partner for Stage V diesel engines?

Perkins already has extensive experience of all the technologies required to meet Stage V emission standards with hundreds of millions of running hours in tough off highway conditions.

These technologies include common rail fuel systems, selective catalytic conversion (SCR), diesel oxidation catalysts (DOC) and DPFs.

The experience of low temperature DPF regeneration on the 1200 Series platform has been particularly successful, and demonstrates Perkins has the ability to bring a field tested, high technology solution to the market with excellent quality performance from day one.

The regeneration in our DPF is continuous, invisible to the machine operator and does not interfere with the duty cycle and workload, so productivity is maintained. Several years of experience in manufacturing and developing engines that work robustly and reliably put us ahead of competitors who didn’t take this path.

We have chosen technology that means minimum change for customers and fits into existing packages where possible.

It’s not just about emissions

So much of diesel engine development for the past 15 years has focused on meeting emissions standards. We see this as a time where we as engine suppliers can work with OEMs to deliver more productive, better value machines. One simple example of this is the increases in power and torque that will be offered on many of our engines.
