🔍 Model Background

The Cummins ISB 6.7 CM2150 (2007–2013) was a key member of Cummins’ midrange engine family, engineered to meet EPA 2007 and interim 2010 emissions regulations while maintaining the company’s hallmark of durability, torque, and fuel efficiency. This electronically controlled diesel engine was commonly used in medium-duty trucks, buses, motorhomes, and vocational vehicles across North America.

Featuring a 6.7-liter inline 6-cylinder configuration, the ISB CM2150 delivered horsepower ratings from 200 to 325 HP and torque outputs up to 750 lb-ft. It introduced or refined several key technologies:

• High-pressure common rail fuel system for precision injection
• Variable Geometry Turbocharger (VGT) for enhanced responsiveness and braking
• Exhaust Gas Recirculation (EGR) to reduce NOx emissions
• Diesel Particulate Filter (DPF) with active and passive regeneration modes

The engine was managed by the advanced CM2150 Electronic Control Module (ECM), which offered more memory, faster processing, and better emissions control than earlier platforms. The CM2150 system also integrated aftertreatment monitoring, service alerts, and full engine diagnostics—a crucial feature for fleet managers and OEMs adapting to tightening emissions rules.

The ISB 6.7 CM2150 platform was widely used in applications such as Dodge Ram trucks (2500/3500/4500/5500), Blue Bird and Thomas school buses, Freightliner M2 trucks, and commercial chassis. It struck a balance between power and compliance, earning a strong reputation for long service intervals, fuel economy, and low operating costs.

This engine laid the groundwork for later emissions-era Cummins models using the CM2250 and CM2350 ECM platforms. Even today, the ISB 6.7 CM2150 remains a popular and well-supported powerplant in the secondary market.
