Engines: 100 Cummins Stage V installations ready to go

Cummins announced its engineers have completed 100 Stage V customer installations to date, with 30% being brand new ones. These include air compressors, back-hoe loaders, dump trucks, fork lift trucks, container handlers, drills, pavers, cranes, excavators, wheeled loaders and snow groomers

From 74 to 503 kW (100-675 HP), Cummins Stage V engines do more with less, delivering benefits for equipment operators and manufacturers. For operators of construction equipment they deliver higher performance for more machine capability. Simpler architecture with fewer parts means more reliability, and more productivity. Improved fuel efficiency with extended service intervals drives lower running costs. The engines are more compact with less weight, less to cool, less installation complexity and lower installation cost for manufacturers.

Whilst most manufacturers have adopted a ‘same as’ strategy from Stage IV to Stage V with little change, Cummins technology leadership has enabled us to deliver improved products with reduced complexity for our customers. For example the Single ModuleTM aftertreatment and its higher NOx conversion capability has supported the removal of EGR from our 3.8 to 9 litre engines. This has positioned us for opportunities with manufacturers who had not necessarily considered Cummins in the past,” said Hugh Foden, Executive Director, Off-Highway Business.

Cummins B6.7 and L9 Stage V products will be certified and ready to start production in April, eight months in advance of the legislated date. They both offer higher power output and torque for improved machine capability. 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 our Stage V engines is delivering down-sizing opportunities for our OEM customers. For example, the B6.7’s increase in capability means that it is replacing engines of higher displacement with no impact on equipment operation. This is delivering reductions in initial installation costs for OEMs as well as running costs for operators,” added Foden.

The F3.8 and B4.5 engines will also be ready prior to the required date of 2020, with substantial increases in power and torque for Stage V. The 3.8-litre moves from 97 kW (130 HP) at Stage IV to 129 kW (173 HP) at Stage V, while the 4.5-litre engine jumps from 129 kW (173 HP) to 149 kW (200 HP). Peak torque of the F3.8 increases by more than 20 percent, to 620 Nm, and an 11 percent increase moves the B4.5 up to 780 Nm.
