The new Cat® C9.3B delivers reliability and durability in a simpler, lighter package with more power and torque



High Performance and Low Operating Costs

The C9.3B combines a new common-rail fuel system with simplified air, electrical, and aftertreatment systems to produce up to 340 kW (456 hp) of power and 2088 Nm (1,540 lb.-ft.) of torque, 18 percent more power and 21 percent more torque compared with its predecessor.

Equipment owners will see this pay off with increased performance, up to 3 percent less fuel consumption and exceptional starting capability in cold climates.

Power Density, Simpler Engine Systems

Patented aftertreatment technology provides a compact design that is 39 percent smaller and 55 percent lighter than its predecessor. Along with removal of the Exhaust Gas Recirculation (EGR) system from the engine, this yields an overall engine system weight reduction of over 12 percent (136 kg / 300 lb).

The C9.3B is designed to allow simple, low-cost installation with high power density up to 37 kW/L (49 hp/L) allowing OEMs to downsize their engine platform without sacrificing performance or reliability.
