Cummins has launched a new generation of clean off-road engines that meet China National Stage IV emissions (CS IV) that started on December 1, 2022. The upgraded engines, with displacements from 2.8 to 15-litres, range from 48-674 hp (36-503 kW).
As part of this launch, Cummins has three new CS IV PLUS engines: The M15 Plus, L9 Plus and F4.5 Plus.
The integration of Cummins latest aftertreatment systems, the single module and switchback, with combustion and air handling technology allows the engines to be EGR free, offering benefits of improved NOx conversion efficiency and better fuel economy.
