Cat extends ratings of C175 propulsion engine

SEPTEMBER 10, 2014 — New power ratings for the Cat C175 propulsion engine for commercial vessels extend Caterpillar Marine’s high-speed engine power range beyond the outputs of its 3516C HD engine.

Designed specifically as a high speed power solution for commercial applications including ocean going and harbor tugs, the C175-16 propulsion engine has a bore of 175 mm (6.9 in) and a stroke of 220 mm (8.66 in) and is now available with ratings of 2,239 bkW – 2,550 bkW @ 1,800 rpm.

“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,” says Nathan Kelly, Caterpillar Marine product definition engineer. “Additionally, the platform also offers improved serviceability, providing more access to the cylinder heads and valve train components.”

Aimed particularly at large, high speed commercial vessels, the C175 engine utilizes proven ACERT technology to optimize turbocharging and aftercooling.

According to Caterpillar, 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 a 1,000-hour oil change interval, thermo-laminated heat shields save time and money during service.

Cat C175 engine platforms with the new ratings are available to order now from the global Cat dealer network.
