瓦锡兰34DF发动机

瓦锡兰，海洋产业解决方案及服务提供商，进一步发展了其双燃料技术和瓦锡兰34DF发动机引入了更强大的版本。产量增加意味着瓦锡兰34DF现在涵盖的功率范围从2.9兆瓦到8兆瓦。除了功率的增加，燃油经济性也提高了，特别是当在液体燃料模式下运行。

2003年以来，瓦锡兰34DF铺平了道路，在液化天然气为燃料的海上支援船市场。今天，这款产品主要用于拖船，渡船，滚装船，滚装-PAX和workboats.The新的和升级版的瓦锡兰34DF发动机提高了工作效率，在液体和气体的操作模式，并提供电源增加高达500千瓦的每缸。

“瓦锡兰34DF发动机的热门选择船东，运营商和码已经很长一段时间，这个下一代版本肯定会加强其受欢迎程度。同时提高动力和燃油效率，我们的目标是保持领先地位，我们在燃气发动机技术和燃气发动机制造商。同样重要的是指出瓦锡兰34DF的环保性能是优秀的，并且通过降低燃料消耗，我们也降低了废气排放量进一步，董事Giulio Tirelli的先生，瓦锡兰船舶动力，四冲程，说：“投资组合与应用。

当工作在气模，瓦锡兰34DF发动机已经符合国际海事组织（IMO）Tier III的规定，没有任何二次废气净化系统。此外，当由气体燃料的硫氧化物（SOx）和CO2排放量显着减少，并实现无烟操作。在液体燃料油模式，瓦锡兰双燃料发动机，完全符合国际海事组织（IMO）Tier II废气排放法规的“73/78防污公约”公约“附件六载。这个引擎可以运作效率和经济上的低硫燃料（<0.1％），使得它适合在排放控制区的操作。

新获得认证的排放标准符合美国环境保护署（EPA）为瓦锡兰34DF进一步赞同这台发动机的环保合规情况。

Wärtsilä, a marine industry solutions and services provider, has further developed its dual-fuel technology and introduced a more powerful version of its Wärtsilä 34DF engine. This increased output means that the Wärtsilä 34DF now covers a power range from 2,9 MW to 8 MW. In addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode.

Since 2003, the Wärtsilä 34DF has paved the way in the LNG-fuelled offshore support vessel market. Today this product is being mainly used in tugs, ferries, Ro-Ro, Ro-Pax and workboats.The new and upgraded version of the Wärtsilä 34DF engine increases the efficiency in both liquid and gas operating modes and offers a power increase up to 500kw per cylinder.

“The Wärtsilä 34DF engine has been a popular choice of ship owners, operators, and yards for a long time already, and this next generation version will certainly enhance its popularity. By improving both the power and fuel efficiency, we aim to maintain the leading position that we have in gas engine technology and as a gas engine manufacturer. It is also important to point out that the environmental performance of the Wärtsilä 34DF is already excellent, and by lowering the fuel consumption we are also lowering the exhaust emissions even further,” says Mr Giulio Tirelli, Director, Wärtsilä Ship Power, 4-stroke Portfolio & Applications.

When operating in gas mode, the Wärtsilä 34DF engine is already compliant with IMO Tier III regulations without any secondary exhaust gas purification systems. Also when fuelled by gas, the SOx and CO2 emissions are notably reduced, and smokeless operation is attained. In liquid fuel oil mode, the Wärtsilä dual-fuel engines are fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention. The engine is able to operate efficiently and economically on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas.

The newly obtained certification of emission standard compliance from the United States Environmental Protection Agency (EPA) for the Wärtsilä 34DF further endorses the environmental compliance of this engine.
