日前,W?rtsil?向市场投放了一款新型中速机——W?rtsil? 31发动机,并声称该机达到了前所未有的燃油效率,柴油型式运行时燃油消耗率为165(g·(k W·h)~(-1))。W?rtsil? 31发动机旨在服务于各种类型船舶,其主机推进功率要求在4.2~9.8MW(与现有W?rtsil? 32机的功率范围相似),该机有三种型式:柴油、双燃料和火花点火(燃气),而发动机的模块化特性使得运营商可轻松地从一种型式转换成另一型式。发动机的模块化特性 W rtsil today introduced a new medium-speed machine, the W rtsil 31, to the market, claiming it achieved an unprecedented fuel efficiency of 165 (g • k W · h) -1. W? Rtsil? 31 engine designed to serve all types of ships, the host propulsion power requirements in the 4.2 ~ 9.8MW (with the existing W? Rtsil? 32 machine power range), the aircraft has three types: diesel, Fuel and spark ignition (gas), while the modular nature of the engine allows operators to easily convert from one type to another.
