C9.3B

Cat® C9.3B Industrial Diesel Engine

C9.3B LRC Diesel Engines - Lesser Regulated & Non-Regulated

DESCRIPTION

The Cat® C9.3B industrial diesel engine is offered in ratings rangingfrom 280-330 kW (375-443 hp). These ratings have been fuel optimized
for use in countries without any regulatory requirements for emissionstandards.

High Performance

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.

Low Cost Maintenance

        
  • Worldwide service delivers ease of maintenance and simplifies the servicing routine.
    •     
  • Standard service intervals of 500 hours under normal operating conditions.
    •     
  • The S•O•SSM program is available from your Cat dealer to optimize oil change intervals.
    •     
  • Ideal for high-hour applications over 10,000 hours.     
              
    • Remote mount options for serviceable items such as oil and fuel filters.
      •     
        

Low Operating Costs

C9.3B development and calibration strategies  have yielded significant improvements in fuel 
consumption, minimizing the total cost of ownership.
