2024 Cummins B6.7N (2018)

Cummins introduces the new B6.7N natural gas engine for the school bus, shuttle, and medium-duty truck markets. Rated up to 240 hp / 560 lb-ft torque, the B6.7N offers a reliable, low-emissions, and low cost option for your fleet. The B6.7N is certified to California Air Resources Board Optional Low NOx standard of 0.02 g/bhp-hr – 90% lower

• 100% natural gas engine, featuring spark-ignited stoichiometric combustion with cooled EGR and a maintenance-free Three-Way Catalyst

• Closed Crankcase Ventilation (CCV) system and On-Board Diagnostics for optimal emissions performance

• Certified to California Air Resources Board Optional Low NOx 0.02 g/bhp-hr – 90% lower

• current EPA standard); exceeds 2017 EPA GHG requirements

• Cost-efficient and reliable performance

Features may include:

A new engine control module, CM2380, provides full monitoring and control of the engine sensors, and the fuel and ignition systems. It offers faster processing to support heavy duty On-Board Diagnostics requirements (500K baud rate). It is also telematics capable, and provides improved diagnostics and durability.

The OBD system continuously monitors the engine and after-treatment system. It gives the vehicle owner or repair technician electronic access to the status of various vehicle subsystems for diagnostic purposes.

The CCV system reduces engine emissions by capturing crankcase emissions and rerouting these gases back to the engine. This results in more complete combustion and lower emissions.

TWCs are effective, simple, passive devices. They provide consistent emissions control performance, are maintenance-free and can be mounted vertically or horizontally on the vehicle. No active aftertreatment such as a diesel particulate filter or selective catalytic reduction is required.

A new Ignition Control Module (ICM) provides better performance and improved spark plug and coil durability, plus self-diagnostics.
