Overview:

On time and on budget

Cummins L9 diesel delivers outstanding productivity with the best power-to-weight ratio in its class. Heavy-duty features such as a replaceable wet liner, roller followers, bypass oil filtration and targeted-piston cooling add years of engine life. Furthermore, transit fleet managers can expect a fuel economy improvement of up to 15 percent compared to buses purchased 10 years ago.

Innovation beyond the engine

An isolated coolant loop for transit buses improves reliability and reduces downtime. A water-to-water heat exchanger is mounted on the engine to provide heat to the passenger compartments as needed, while providing a self-contained coolant flow to the engine compartment area. This reduces potential coolant leakage and air infiltration so the Exhaust Gas Recirculation (EGR) cooler operates with greater reliability and durability.

Cummins designs, develops and supports every component, from the air handling to the exhaust aftertreatment, to work as a totally integrated system – so we can optimize every function better than other engine manufacturers.

  • VGT® Turbocharger from Cummins Turbo Technologies - The patented design is widely recognized as an industry performance leader. Electronic actuation improves precision and responsiveness. The VGT Turbo is a key element in providing exceptional fuel economy and braking horsepower

  • Connected Diagnostics™ - Wirelessly connects your engine to Cummins through a telematics device for immediate diagnosis of a fault alert. Provides a clear recommendation for continued operation, or the need for service, within seconds.

  • XPI Fuel System from Cummins Fuel Systems - Delivers superior performance even in lower engine rpm ranges. Enables multiple injection events per cycle, for improved fuel efficiency with quieter, smoother operation.

  • Single Module Aftertreatment From Cummins Emission Solutions - Combines high-efficiency SCR, a more reliable dosing unit and a DPF into a single flow-through unit. It is up to 70 percent smaller, so it’s easier to install, and as much as 30 percent lighter than the aftertreatment units it replaces. Better heat management improves fuel efficiency and minimizes periodic maintenance.

  • Fuel Filters And Lube Filters From Cummins Filtration - Fleetguard® filters protect against corrosion and contaminants with innovative technology, including NanoNet® media, which provides 10 times better protection than conventional fuel filters.

  • Single High-Capacity Electronic Control Module (ECM) - A higher capacity offers faster processing of more information, fully integrated control over the engine and aftertreatment system for optimized performance and improved engine lamp strategy.
