Caterpillar Marine High Speed Cat? C175 Engine

Caterpillar Marine will unveil new power ratings for the Cat® C175 propulsion engine for commercial vessels at the 2014 SMM Exhibition, held September 9 -12 in Hamburg, Germany. Designed specifically as a high speed power solution for commercial applications including ocean going and harbor tugs, the C175-16 propulsion engine is now available with ratings of 2239 bkW - 2550 bkW @ 1800 rpm. The new ratings extend Caterpillar Marine’s high-speed engine power range beyond the company’s already industry-leading 3516C-HD engine. Cat C175 engine platforms with the new ratings are available to order now from the global Cat dealer network.

“Designed to improve total vessel profitability by providing durability with unmatched power output, the C175 offers ample benefits to our tug and salvage customers as a durable, high performance performer,” Nathan Kelly, Caterpillar Marine product definition engineer noted. “Additionally, the platform also offers improved serviceability, providing more access to the cylinder heads and valve train components.”

Ideal for large, high speed commercial vessels, the C175 engine utilizes proven ACERTTM to optimize turbocharging and aftercooling. Efficient combustion reduces engine wear and maximizes fuel, driving the C175-16 to pull the maximum amount of energy from each injection event. The engine also features the Cat common rail fuel system enabling low emissions at all levels and requires no aftertreatment to comply with regulations. In addition to an 1,000-hour oil change interval, thermo-laminated heat shields save time and money during service.

With a bore of 175 mm (6.9 in) and a stroke of 220 mm (8.66 in), the C175-16 is highly efficient while providing increased propulsion output in a high speed engine platform. Additional features include:

Turbocharged and aftercooled aspiration
MCS approved monitoring, alarm, and protection system
Cross-flow head design
Simplified electrical system
