Cummins has announced that its latest B6.7 and L9 Stage V engines are now fully certified and in production at its Darlington UK plant.
“These engines do more with less, offering higher power output and torque for improved machine capability in a smaller, lighter package that is cheaper to run,” said Eric Neal, executive director of Cummins’ off-highway business.
“Simpler architecture with fewer parts means they are more reliable and more productive.”
Top-rated power for the Stage V B6.7 moves up to 326 hp with a peak torque of 1,375 Nm – a 30% increase over that of Stage IV. The L9 top rating increases from 400 hp up to 430 hp at Stage V, together with a 13% increase in peak torque to 1,846 Nm.
The higher capability of these engines is intended to deliver downsizing opportunities for equipment manufacturers. With increases in power and torque, they can replace engines of higher displacement with no impact on equipment operation and provide installation cost savings for OEMs.
“Cummins capability to tailor engine power and torque curves to the specific operational needs of key installations such as wheeled loaders, excavators and material handling equipment using our in-house technologies, like turbocharging and exhaust after-treatment, is also enabling OEMs to be more competitive,” added Neal.
Cummins engineers have completed over 100 Stage V customer installations to date, with 30% of these installations are for new equipment with current and new customers. These include air compressors, back-hoe loaders, dump trucks, fork lift trucks, container handlers, drills, pavers, cranes, excavators, wheeled loaders and snow groomers.
