摘要

Caterpillar Marine has commercially launched its new Cat 3516C engine, which is certified to US EPA Tier 4 standards, as well as being IMO Tier Ⅱ and Ⅲ compliant. The 3516C, which is particularly suited to tug and salvage and offshore vessels, is available in a 'B' rating of 2,240bKW at 1,800 rpm and a 'C' rating of 2,350bKW at 1,800rpm. An auxiliary engine and a diesel-electric solution are both available in a rating of 2,250ekWat 1,800rpm. Cat Tier 4 marine technology utilises after-treatment combined with an optimised engine to meet low NOx regulations. The engine employs the Cat Clean Emissions Module which incorporates selective catalyst reduction (SCR) technology, designed to provide low owning and operating costs. Additionally the inclusion of SCR technology enables customer to leverage shared components as well as a similar engine footprint to EPA Tier 2 and Tier 3 engines.
