1. THE PROVEN CHAMPION
- Over 33 years of global production and experience, with over 600,000 B-Series engines produced every year
- A long history of industry innovation and reliability, tested and proven across the harshest environments and extreme applications
2. BEST-IN-CLASS DURABILITY
- When both engines are producing the same amount of power, pressure exerted on each piston during the power stroke is spread across 6 cylinders (B6.7) vs. 4 cylinders (DD5). This results in a lower BMEP (Brake Mean Effective Pressure) rating, or less average pressure exerted on the piston during each power stroke.
-
Less stress per cylinder reduces the overall stress on the engine and increases engine life
3. NO REPLACEMENT FOR DISPLACEMENT
- Larger displacement engines are capable of producing higher torque at lower rpms
- Higher torque means smoother performance and an ability to handle greater loads
- Inline 6 cylinder engines are naturally balanced producing less noise, vibration and harshness for improved driver comfort
4. LESS COMPLEX, MORE RELIABLE
- The B6.7 uses a proven and simple Cummins Variable Geometry Turbocharger (VGT) that delivers superior performance under all operating conditions
- A two-stage turbocharger solution is complex, heavier and more difficult to service
5. UNMATCHED SUPPORT
- The B6.7 features the largest service network in the industry with over 3,500 service locations in the US and Canada
- With over 12 million B-Series engines produced globally, the B6.7 has the largest network of trained and certified technicians in the world
- Well established distribution centers ensure parts are widely stocked for best-in-class availability
