Cummins has announced that 100 manufacturers are ready for Stage V after having had their vehicles equipped with the company’s compliant engine – nearly a year in advance of it coming into force.
The range of engines offering between 74kW and 503kW (100-675hp) has been included in air compressors, back-hoe loaders, dump trucks, forklift trucks, container handlers, drills, pavers, cranes, excavators, wheeled loaders and snow groomers.
The engine has been designed to do more with less. Weighing less than its Stage IV relatives, the compact unit has a relatively simple architecture meaning there are fewer parts, so providing more reliability and efficiency.
“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,” said Hugh Foden, executive director for Cummins off-highway business.
“For example, the single module TM aftertreatment and its higher NOx conversion capability has supported the removal of EGR from our 3.8- to 9-liter engines. This has positioned us for opportunities with manufacturers who had not necessarily considered Cummins in the past.”
Both the company’s B6.7 and L9 Stage V products will be certified and ready for production in April – eight months before the legislated date for Stage V to commence. Offering 326hp/1,375Nm and 430hp/1,846Nm respectively, both engines have increased power significantly on the Stage IV versions.
“The higher capability of our Stage V engines is delivering downsizing 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.
