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.
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.
