Cummins L9.3 Engine Overivew

L9 (STAGE V)

More With Less.

Cummins L9 is a medium-duty engine with heavy-duty components and performance characteristics, including an 8 percent increase in power and a 13 percent increase in torque versus the current model.

Increased fuel economy and longer maintenance intervals contribute to a reduced cost of operation and lower Total Cost of Ownership.

Cummins award-winning VGT™ Turbocharger features precise electronic activation with fewer moving parts than multi-vane designs, for enhanced precision, reliability and durability.

EGR-free architecture reduces complexity, improves reliability and reduces the cooling system space claim. Multiple component options include a choice of front or rear-sump oil pan locations, on-engine or remote-mounted options for ECM and maintenance filters, the option of Rear Engine or Front Engine Power Take Offs, plus your choice of four turbocharger orientations; high-mount front and rear, or low-mount front and rear. This allows for easier installation by OEMs and easier maintenance for equipment users.

The compact Single-Module™ aftertreatment system combines DPF, SCR and urea-dosing in one unit which takes up 50 percent less space and weighs 30 percent less than the prior system.

L9 owners also benefit from Cummins Connected Diagnostics™, remote monitoring technology that wirelessly connects the user’s engine to product experts for instant analysis and recommended action the moment a fault code is generated on any piece of equipment equipped with a telematics.

The L9 is available with Cummins Guidanz™ technology, which provides a seamless, process-guided package that streamlines the diagnosis and repair process, ensuring that the right parts, tools and support can be brought onsite to speed up repairs.

High sulfur tolerance allows OEMs to install the same L9 in equipment regardless of where it will be utilized or moved - anywhere around the world.
