The C175-16 from Caterpillar is thefirst Cat engine with core ACERT Tech- nology, designed and built from the ground up, according to Robert Hallen-gren, Marine Products Director, Cater- pillar Marine Power Systems. It offers maximum performance along with EPA Marine Tier 3 and IMO Tier II emissions compliance with no after treatment, andis positioned to comply with EPA Tier 4 and IMO Tier III rules. Introduced in Germany at the SMM exhibition, the en- gine already has more than two years field experience in other industries, in- cluding mining trucks and stationarypower, and is moving now into marine and offshore oil and gas applications. It is available today in the 2001 to 2168 bkW power range; and will be available starting in early 2013 in the 2239 to 2550bkW range. With unrestricted continuous and heavy-duty ratings, you get more power with plenty of room for growth, so you maximize productivity while minimizing cost of ownership. The C175-16 is simply one plank inthe Cat platform to broadly expand its strategic focus on maritime assets and their power needs, according to Nigel Parkinson, Managing Director, Caterpil- lar Marine Power Systems. ?We are in- vesting twice as much in R&D as we were 3 years ago, to help fill some of the product gaps,? he said. The C175-16 is positioned as a fullyintegrated marine power sy stem, and boasts 13% more power for increased productivity, and a standard warranty on all factory packaged components to help drive down the overall cost of ownership.

C175-16 Design Features 1 Caterpillar Common Rail Fuel System This system features electronically controlled, fully flexible injec- tors, enabling optimal combustion and low emissions at all levels, along with better transient response. 2 Cross-flow head design Improved airflow helps the air/exhaust flow meet emissions and optimize fuel consumption. 3 Simplified electrical systemAllows for easy installation and maintenance, reducing up front and service costs. 4New generation of turbochargers designed specifically for the C175  Cast titanium impeller offers five times longer low-cycle fatigue life, and compressor blades are twice as resistant to high-cycle fatigue.  Turbochargers are mounted on cast pedestals and center-positioned to eliminate external oil drain lines, reducethe chance of oil leaks, and improve turbo efficiency. The flexible bellows connections used on inlets/outlets of the turbine and compressor housings minimize leakage and provide isolation from external vibrations, motions, and thermal expansion.5Marine Classification Society approved monitoring, alarm, and protection system: Offered as a factory-installed and warranted option; single source for the whole package. 6 Thermo-laminated heat shields for exhaust components Easier to install and remove, they save time and money during service. The no-gap fitting enhances safety with better hot spot coverage.?We are investing twice as much in R&D as we were 3 years ago, to help fill some of the product gaps?
