Millbrook Group, the leading independent vehicle test, validation, and engineering service provider and owner of winter and tyre testing specialists, Test World, has welcomed the introduction of new real driving emissions regulations that update vehicle testing requirements. The new procedures require the use of a sophisticated Portable Emissions Measurement System (PEMS) to provide real world results to supplement laboratory testing.
Type-approval emissions requirements for motor vehicles have been tightened significantly through the Euro standards. While there have been emissions reductions across a range of regulated pollutants, further improvements in this area are required in order to improve air quality, particularly in urban areas where exceedances are being seen over European air quality targets. A particular area of concern relates to NOx emissions, principally from diesel engines, to which current high levels of primary NO2 concentration are related.
The new Real Driving Emissions (RDE) Regulation (Package 1) has now been published and outlines the procedures that must be followed when testing exhaust emissions of passenger cars and light commercial vehicles. The revised testing process requires the use of a Portable Emissions Measurement System (PEMS) to provide results that are more representative of real-world driving conditions. The latest equipment provides full gaseous measurements of CO, NOx, NO, NO2, CO2 and O2.
Package 2 of the Real Driving Emissions Regulation is expected to be announced later in 2016 and will outline emissions limits that manufacturers will be required to comply with. While those limits are due to be published later this year, compliance will not be enforced until September 2017.
Phil Stones, Chief Engineer, Powertrain, at Millbrook, says: “It’s important to note that the changes to emissions testing regulations are not a knee-jerk reaction to the events of recent months, but have been a long time in the planning. The Package 1 regulation became a mandatory part of Type Approval from the 20th April and from 2017 specific emissions targets will be imposed. Our view is that these changes will create the right framework for the industry to adhere to and will provide consumers with the clarity they require.”
Millbrook Group became an early adopter of PEMS and has conducted a number of projects across light, heavy and off-road vehicles accurately and repeatedly to gather key data that will help shape future technologies and fuels. At its Proving Ground in the UK, Millbrook has three of the latest PEMS units available, from each of the major suppliers, to support the industry’s testing requirements. The company has been using Powertrain & PEMS equipment since 2013 and has extensive experience of the procedures required under the new regulations.
