The upgraded engines, with displacements from 2.8-15litres, range from 36-503kW. Cummins says that they achieve higher power output and torque than their predecessors.
The integration of Cummins latest aftertreatment systems, the single module and switchback, with leading combustion and air handling technology allows the B6.7, L9, X12 and M15 CS IV engines to be free of EGR (exhaust gas recirculation), offering benefits of improved NOx conversion efficiency and better fuel economy.
As part of this launch, Cummins says that it has three new CS IV PLUS engines that will exceed customer expectations, delivering market leading CS IV power, with faster response and smarter system integration capability, helping operators reduce running costs and the environmental impact.
The M15 Plus is a new member of the bright red Cummins engine family for use with excavators, wheeled loaders, drilling rigs, road planing and milling machines and air compressors. Power ranges from 420-503kW with peak torque up to a significant 3,000Nm.
The CS IV compliant Cummins L9 Plus engines with power ratings from 219-294kW reach a whole new level of power and versatility derived from millions of L Series engines in service around the world.
Meanwhile, the 4-cylinder F4.5 Plus at 129kW is ideally suited for excavators, with a design that is based on the highly successful F Series engines of which around 1.8 million are in use across the globe. It delivers a power increase of up to 20% over its CS III predecessor.
Cummins EU Stage V engines, developed as a universal engine platform, will be co-certified to meet CS IV regulations to help OEMs reduce the complexity involved with powering their global equipment platforms.
