Cummins Stage V B6.7 and L9 Certified and in Production

Paris, France

Cummins announced that is 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. Simpler architecture with fewer parts means they are more reliable, and more productive,” said Eric Neal, Executive Director, Cummins Off-Highway business.

Top-rated power for the Stage V B6.7 moves up to 243 kW (326 hp) with a peak torque of 1375 Nm – a 30 percent increase over that of Stage IV. The L9 top rating increases from 298 kW (400 hp) up to 321 kW (430 hp) at Stage V, together with a 13 percent increase in peak torque to 1846 Nm.  The higher capability of these engines is delivering down-sizing opportunities for our equipment manufacturers.  The increase in power and torque means that they are replacing engines of higher displacement with no impact on equipment operation, and providing 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 aftertreatment, is also enabling OEMs to be more competitive,” added Neal.  
Cummins engineers have completed over 100 Stage V customer installations to date, with more planned.  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.
