CAT(R) C-9 INDUSTRIAL ENGINE PROVIDES HIGH PERFORMANCE WHILE MEETING EMISSIONS STANDARDS


PEORIA, IL - Caterpillar offers high performance while meeting emissions standards with the C-9, 350 hp industrial engine. This engine is the highest rated C-9 with an increase of 15 hp. The 8.8-liter engine comes in a small compact package and began production in January 2002.

The C-9 is an in-line, six-cylinder, air-to-air aftercooled engine offering the Caterpillar ADEM(TM) III controller and HEUI(TM)-B fuel system. The ADEM III is an electronic control module (ECM) that provides more control input and output allowing additional features to be added or parameters controlled and monitored.

Caterpillar's HEUI fuel system utilizes hydraulically actuated, electronically controlled unit injectors and allows complete, adjustment-free electronic control of fuel injection pressure, timing and duration. This provides greater flexibility for programmed electronic control strategies that determine engine performance and emissions control characteristics.

Despite the demands on fuel economy stemming from the Tier 2 and Stage II standards, the C-9 offers significant fuel savings. A mid-supported wet liner allows higher top piston ring position for better fuel consumption and reduced emissions.

The C-9 is also available in 275 - 335 hp, and is rated 1800 - 2200 rpm for industrial applications.

Caterpillar is the world's leading manufacturer of construction and mining equipment, diesel and natural gas engines and industrial turbines. Headquartered in Peoria, Illinois, the company posted 2001 sales and revenues of $20.45 billion.
