CUMMINS EURO 6 ISB ENGINES NOW CERTIFIED

Author : Date : 2013-6-20 9:26:03
Cummins announced that their latest ISB engines have now been certified to the Euro 6 standards, ready for January 2014. Displayed on Cummins stand 4C300 at UITP, Geneva, these engines have met the all of the stringent levels of particulate matter and oxides of nitrogen when measured on the World Harmonised transient and steady state test cycles. The more challenging on-board diagnostics (OBD) regulations have also been achieved.
Available from 150 to 310 ps, the ISB engines are ideal for single and double deck buses and coaches. They use the proven engine technologies of cooled exhaust gas recirculation (EGR) and variable geometry turbocharging (VGT), tailored for European vehicle design and operations. The engine technologies are matched to the aftertreatment system, designed and manufactured by Cummins Emission Solutions. It combines a Diesel Particulate Filter (DPF) with Selective Catalytic Reduction (SCR) to meet the ultra-low levels of emissions.
The successful certification is a result of the 3 year ISB Euro 6 development programme. A key part of the plan has been to prove they operate successfully in extreme hot and cold climates. Engineers carried out more than 30,000 km of product validation in challenging vehicle operating conditions in Spain and Scandinavia to ensure emissions compliance. Ambient temperatures ranged between 35C and -29C during the tests, which also took the vehicles to altitudes of more than 2000m.
