Kortrijk, Belgium (October 20, 2011) - On the eve of Busworld, Cummins confirms that the second package of legislation has now been written and approved by member states, so all regulatory requirements that make up Euro VI are now known.  


Neil Pattison, Cummins Automotive Sales Director for Europe, Middle East and Africa said: “Cummins Euro VI development programme continues, with the first stage of hot climate testing now successfully completed.  The engines are performing extremely well, and will be fully available in time for the dates set out in the legislation.”


“Based on the expected timing for publication of the second package of legislation, we believe that full Euro VI type approval will not be possible until late in the first quarter or early in second quarter of 2012,” he added.


The first package of legislation (582/2011) has been published, including the emission limits, introduction dates and On-Board Diagnostics requirements (OBD).  The second package of legislation is focused on methods the EU is introducing to ensure that products maintain their emissions capabilities throughout their useful life. 


Firstly, it brings similar repair and maintenance information requirements to those introduced in the light duty legislation.  This will drive vehicle and engine manufacturers to provide service information for key parts of their systems, giving independent service organisations what they need to service the vehicle effectively while maintaining the emissions levels.


Secondly, the EU has specified a need to run an in-vehicle emissions test at the point of type approval.  So in addition to the in-cell emissions cycles, portable emission measurement devices need to be used on a vehicle operating on a standard duty cycle.  It must demonstrate that the emissions are no more than 1.5 times the in-cell limit.


These are supported by the more challenging OBD requirements set out in the legislation, which monitor vehicle emissions in normal operation. The additional OBD requirements will be phased in over a three year period, becoming more challenging at each step. 


During 2015 a particulate threshold will be introduced for the first time, measuring soot emissions in the exhaust pipe.  Previously only NOx emissions have been measured.  Then, in 2016, a lower NOx OBD measurement will be introduced which ensures a sufficient urea flow to maintain the correct emissions level.


Once an emission control issue is detected through the OBD system, the driver warning system must be activated within a certain time.  If the issue is not resolved within a further period the driver inducement system will be activated, which will reduce torque and vehicle speed unless corrective action is taken.
