Cummins has announced that it will begin full production of Phase D-certified Euro VI engines at its Darlington factory before 1 September, when the Phase D regulations come into force.
The ‘clean diesels’ in question are the B4.5, B6.7 (pictured) and L9 engines with a 148bhp to 395bhp range for bus and coach applications.
The Euro VI Phase D engines achieve “nearer-to-zero emissions”, says the manufacturer, representing an incremental step towards Euro VII regulations, anticipated to take effect after 2025.
Cummins says tests have shown the latest engines can deliver a 25% reduction in NOx emissions compared to the first Euro VI engines introduced in 2015.
“With exceptionally low NOx emissions, our latest Phase D products will help bus fleets improve air quality and align with the recent arrival of the London ultra low emission zone and other clean air zones being established in cities across Europe,” says Ashley Watton, Cummins director for on-highway business Europe.
