Cat® C9.3B Diesel Engine

Cat® C9.3B Diesel Engine

The Cat C9.3B combines a new high pressure common rail fuel system and advanced aftertreatment technology to produce 340 kW of power. With exceptional power density, the C9.3B allows for platform downsizing while maintaining reliability and durability. Our focus is locked on maximizing performance with simpler engine systems and reduced installation complexity through modular, flexible designs.
