Cat ACERT marine engines with WOSR capability

摘要

Modern high-speed, electronically-controlled diesel engines offer a number of benefits for operators of tugboats, towboats and offshore supply vessels, especially when it comes to transient response and emissions reduction. To cope with ever-decreasing regulatory limits on Nitrous Oxides (NOx) and Paniculate Matter (PM) emissions, most engine manufacturers are focusing their technology development efforts on improving fuel systems. The focus of Caterpillar Marine Power Systems (CMPS) goes beyond that. Exploiting the advantages of ACERT technology in other emission-sensitive markets like truck or electric power generation to comply with regulatory marine emissions requirements, research has concentrated on additional engine technology advancements of benefits to customers, in particular on Wide Operating Speed Range (WOSR) capabilities in Cat highspeed engines.
