A Year of Expansion 2010 brought many additions to Cat erpillar Inc., including rail, power generation and emission systems acquisitions. Notably, Caterpillar’s subsidiary Progress Rail purchased EMD; the company recently announced its acquisition of Germany-based MWM; and earlier this year, Cat acquired CleanAIR Systems, Santa Fe, New Mexico, U.S.A., expanding its portfolio of emission reduction technology and systems.

Additional C18 Power Range Caterpillar Marine Power Systems has introduced a 685 kW rating for its C18 ACERT marine diesel engine. The new rating joins the 1015 and 1150 kW ratings already available on the inline sixcylinder, four-stroke, 18.1 L C18. The engine is electronically governed, turbocharged and aftercooled. The additional power rating is expected to increase fuel efficiency upward of 25%, said Caterpillar. It is compliant with IMO, EPA Tier 2 and EU 94/25/EC Recreational Craft Directive emission regulations.
