www.chinabuses.org: Kortrijk, Belgium (October 16, 2015) – Visitors to Busworld at the Kortrijk Xpo today were able to view the latest Cummins ISB engines with new Smart Efficiency ratings for 2017, complying with the upcoming Euro 6 OBD C requirements*. Displayed on stand 407, these engines will be in production in the fourth quarter of 2016. OBD C is the latest step in the Euro 6 legislation and affects new vehicle type approvals from 31st December 2015 and all vehicles from 31st December 2016. The key changes to the regulations impact the On Board Diagnostics (OBD) requirements as follows;
?
The NOx emissions threshold detected by the system is reduced from 1500mg/kWh to 1200mg/kWh
?
Particulate Matter emissions detection threshold is introduced at 25 mg/kWh
?
The level at which sub-standard quality Adblue is detected is lowered from 0.9g/kWh to 0.46g/kWh
?
OBD diagnostic operation must report how many times the monito r actually successfully runs per the number of drive cycles Claudio Barcena, Cummins Regional engine Sales Leader, said: “E uro 6 has been the most technically challenging emissions step to date. Our l eadership in engine driveline integration means we have achieved it successfully, with more installations than at Euro 5. We don’t stop there though, as our engineers continue to partner with vehicle manufacturers and operators to gain a deeper understanding of their business and how our engine technologies can be tailored to deliver improved fue l efficiency and cost of operation. These findings are being incorporated in our 2017 p roducts.”

The ISB4.5 4 cylinder engine moves up to a new peak torque of 850 Nm from 760 Nm. The ISB6.7 6 cylinder engine moves to a high peak torque of 120 0 Nm from 1100 Nm along with a new 300 hp/224 kW top bus rating as well as a new 320hp/239kW top rating for coaches. These improvements increase the sco pe of Cummins product offerings for the bus and coach sectors, being suitable for wider range of ap plications, vehicle weights and duty cycles.
It supports the demands of European bus operators by offering a dded value in a market where competitive fuel economy and total cost of operation are critical success factors. Potential savings have already been seen by even clo ser matching of engine performance characteristics to vehicle types and modes of opera tion. Cummins capability to offer greater power density with no impact on displacement i s a key factor behind this.
“Euro 6 has changed the landscape for engine installation and operation, and the previous rules don’t apply. Our objective for 2017 has not just been to meet the legislated requirements but to provide impr oved performance and efficiency with no changes to displacement or hardware. We will continue to learn alongside our customers and drive improvements which sustain the ISB’s position as market leader, ” added Barcena.
