2023 Cummins L9N for Euro Truck & Bus L9N
The L9N is the natural choice in alternative-fuel engine technology. With industry leading performance, it combines all the advantages of clean burning, low cost natural gas with “no compromises” in power and torque. The L9N is an upgraded evolution of the proven ISL G, moving to the latest Euro 6 Phase D emissions with minimal changes retaining the impressive low-end toque, transient response and quiet operation for bus and truck applications.
The L9N engine block is shared with the Cummins L9 diesel – a full skirted block for increased rigidity and strength. The design provides superior piston ring and bearing life, improved coolant flow and targeted piston cooling, for greater reliability and superior durability. The engine’s life to rebuild and rebuildability are similar to those of diesel engines. The 8.9 litre L9N uses advanced stoichiometric combustion with cooled Exhaust Gas Recirculation (EGR) to meet ultra-low emissions requirements. The cooled-EGR system takes a measured quantity of exhaust gas and passes it through a cooler to reduce temperatures before mixing it with fuel and the incoming air charge to the cylinder. This lowers combustion temperatures and knock tendency, reducing engine out emissions and noise. With a pedigree of millions of engines to date, Cummins cooled EGR technology is proven in a wide range of installations.
Features may include:
- Factory-Built, Dedicated Natural Gas Engine – manufactured by Cummins on the same assembly line as Cummins diesels, the L9N shares many components and parts with Cummins L Series diesels, inheriting their renowned simplicity.
- Heavy-Duty Design – rugged features include replaceable wet liners, roller followers, by-pass oil filtration and targeted piston cooling for longer service in the toughest work environments.
- Fuel Capability – the L9N is capable of operating on compressed or liquefied natural gas (CNG, LNG). The L9N can also operate on up to 100 percent biomethane, renewable natural gas made from biogas or landfill gas that has been upgraded to pipeline and vehicle fuel quality.
- Air/Fuel Regulation – Cummins closed-loop electronic control system with sensors for engine parameters, including intake manifold pressure and temperature, fuel inlet pressure, knock detection, air/fuel ratio and fuel mass flow.
