Spanning 100 to 512hp (or 74-382 kW), these new engines are designed to meet 2019 European Union Stage V emissions regulations and are suitable for a range of ground support equipment, from aircraft tractors and cargo hi-lifts to de-icing rigs and snow blowers.
The F3.8, L9 and X12 engines all set new benchmarks in their class. Providing higher power and torque than their Stage IV predecessors, they will allow unprecedented levels of performance and are expected to deliver increased machine capability. In fact, Cummins believes that manufacturers can consider engine downsizing without any impact on equipment operation.
All of these engines are designed with exhaust gas recirculation-free architecture and are fitted with Cummins' latest after-treatment technologies to meet the stringent levels of Stage V. This selection will enable an easier installation, with a high degree of flexibility across emissions levels for exporters.
In particular, the F3.8 and L9 engines use Cummins' single module after-treatment, which achieves higher NOx conversion efficiency than previous models, thanks to a high-flow dosing capability. This can remove 99.9% of particulate material by weight and count; usefully, the system is smaller and lighter than equivalent Stage IV packages. The X12 engine employs the Cummins SCR/DPF after-treatment, carried over from Stage IV.
