PRODUCT Detail
For better reliability in 2017 and going forward, with transit ratings an isolated coolant loop – a water-to-water heat exchanger – will be engine-mounted to provide heat for passenger compartments as needed, while providing a self-contained coolant flow to the engine. This new approach reduces the chance for coolant leakage and air infiltration for better Exhaust Gas Recirculation (EGR) Cooler reliability and durability.
Connected Diagnostics: Smarter Route Management with Connected Diagnostics
Transit bus drivers have enough to pay attention to without being concerned about engine fault codes. In the rare event that one is triggered while the bus is in operation, it can be diagnosed immediately over the air, through the addition of Connected Diagnostics. Cummins Connected Diagnostics delivers real-time engine fault code analysis, with a probable diagnosis and a recommended action for buses that are equipped with telematics.
