The C9.3B delivers expanded capability with 19% more power and 16% more torque than the previous 8.8 liter platform for less regulated countries (comparison for IND-C rating).

Reliable, Quiet and Durable Power

The C9.3B engine leverages a core engine with over 200 million off-highway hours in the field and is manufactured in a world-class facility; assuring reliability, quiet operation and many hours of productive life.

Optimized Installation

          
    • The C9.3B for LRC offers platform commonality with the C9.3B for highly  regulated countries to reduce cost of installation and support a global customer base by sharing a common core engine, offering similar machine interfaces and controls architecture.
    •     
    • High power density, up to 33.3 kW/L (44.7 hp/L) gives original equipment manufacturers (OEMs)
          the ability to downsize their engine installation without sacrificing performance.
    •     
    • Fully configurable engine options and industrial power unit (IPU)  available from factory to avoid 
          significant design, validation, and manufacturing costs.
