Heavy Duty Power, Heavyweight Durability

The new C15 combines series turbochargers, a higher compression ratio, and higher cylinder pressure to produce improved performance, better throttle response and increased fuel economy. Like all heavy duty engines with ACERT technology, the C15 also features rugged components such as steel single-piece low friction pistons, a four-bolt connecting rod and a high-efficiency water pump.

One of the toughest power plants on the road today, this engine is made for owner-operators, fleets and heavy haulers who want high horsepower performance combined with unmatched durability and superior resale value. Peak torque ratings up to 1850 lb-ft offer excellent startability and exceptional hill-climbing capability.

• Excellent reliability with proven MEUI fuel system and Cat exclusive "leak-free" technology
• Superior fuel economy and reduced emissions with variable valve actuation
• Improved durability with new high efficiency water pump and four-bolt connecting rod design
• Driver pleasing performance and improved engine response with series turbochargers

Payload-Pulling Power to Rely On

Continuing the legacy of reliability established by the Cat C-12, the new C13 evolves from a uni-flow cylinder head design to a cross-flow setup, with improved breathing ability and better responsiveness. Like the new C15, it also features a higher compression ratio, higher cylinder pressure, and series turbocharging for improved power, performance and fuel economy.

The engine of choice for fleets requiring excellent performance and dependability in a lightweight package, the C13 weighs in at just 2,270 lb (1030 kg) and features the industry's best horsepower-to-payload ratio. Compared to other engines in its horsepower range, it provides up to 800 lb (363 kg) of additional payload capacity for pulling power to spare.

• Reduced emissions with Caterpillarpatented variable valve actuation
• Million-mile durability from robust component design and increased oil sump capacity
• Superior fuel economy from series turbochargers and Cat MEUI fuel system
• Improved head gasket design and higher efficiency from cross-flow head design

Day Cab and Vocational Fleet Specialist

The C11 replaces the C-10 engine and provides increased displacement and resulting longer engine life. The C11-like the C13-features a cross-flow head design complete with series turbochargers and variable value actuation. An optional Cat compression brake, and rear-mounted power take-off (PTO) are available to fit your specific application. Heavy duty components, scaled from the C13 result in a highly reliable, durable powerplant.

A unique combination of heavy duty components, in a lightweight package make the new C11 a perfect engine for both day cab and vocational applications.

• Excellent fuel economy from variable valve actuation and Cat MEUI fuel system
• Improved head gasket design and Cat exclusive "leak-free" technology provide increased reliability
• Durability is enhanced from new connecting rod, piston, cylinder head and water pump designs
• Rear-mounted power take-off provides flexibility for spec'ing into unique applications

Light on Weight, Heavy on Features

The new C9 is designed for durability and reliability. It features rugged, heavy duty components normally featured in much larger engines. In addition, the C9 offers both front and rear power take-off (PTO) capability.

The C9 is ideal for vocational applications and regional line haul fleets that require a responsive, lightweight engine with electronic controls. Its rare combination of light weight and robust design produces an engine perfectly suited for the toughest applications. The reliability of the C9 exceeds Caterpillar's most rigorous standards, so you can count on this engine to remain dependable for years to come. A combination of mid-supported wet-liners, heavy duty crankshaft and HEUI fuel system provide a perfect engine for demanding applications.

• Heavy duty durability from midsupported wet-liner and robust component design
• Excellent fuel economy and performance plus lower emissions from four-valve cross-flow head design
• Superior reliability from proven HEUI fuel system and Cat designed electronics
• Flexible front and rear power take-off capability for multiple vocational applications

Maximum Mid-Range Versatility

The new C7 engine with ACERT technology continues the tradition of bottom-line value. A wide range of horsepower ratings-all the way up to 330 hp for fire trucks and RVs-ensures a perfect fit for a variety of applications. This engine features the Caterpillar-patented HEUI fuel system for unsurpassed performance and reliability. Full electronic controls include features typically found only on heavy duty engines. Both front and rear power take-off (PTO) options are available to fit your specific application.

The C7 is a sophisticated mid-range engine suitable for a wide variety of vocational applications, from construction and utility jobs to pick-up and delivery, RV and emergency vehicles.
