L9 for Transit and Shuttle Bus (2021)
194 - 283 kW
1166 - 1695 N•m
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.
