瓦錫蘭34DF發(fā)動機(jī)

瓦錫蘭，海洋產(chǎn)業(yè)解決方案及服務(wù)提供商，進(jìn)一步發(fā)展了其雙燃料技術(shù)和瓦錫蘭34DF發(fā)動機(jī)引入了更強(qiáng)大的版本。產(chǎn)量增加意味著瓦錫蘭34DF現(xiàn)在涵蓋的功率范圍從2.9兆瓦到8兆瓦。除了功率的增加，燃油經(jīng)濟(jì)性也提高了，特別是當(dāng)在液體燃料模式下運(yùn)行。

2003年以來，瓦錫蘭34DF鋪平了道路，在液化天然氣為燃料的海上支援船市場。今天，這款產(chǎn)品主要用于拖船，渡船，滾裝船，滾裝-PAX和workboats.The新的和升級版的瓦錫蘭34DF發(fā)動機(jī)提高了工作效率，在液體和氣體的操作模式，并提供電源增加高達(dá)500千瓦的每缸。

“瓦錫蘭34DF發(fā)動機(jī)的熱門選擇船東，運(yùn)營商和碼已經(jīng)很長一段時(shí)間，這個(gè)下一代版本肯定會加強(qiáng)其受歡迎程度。同時(shí)提高動力和燃油效率，我們的目標(biāo)是保持領(lǐng)先地位，我們在燃?xì)獍l(fā)動機(jī)技術(shù)和燃?xì)獍l(fā)動機(jī)制造商。同樣重要的是指出瓦錫蘭34DF的環(huán)保性能是優(yōu)秀的，并且通過降低燃料消耗，我們也降低了廢氣排放量進(jìn)一步，董事Giulio Tirelli的先生，瓦錫蘭船舶動力，四沖程，說：“投資組合與應(yīng)用。

當(dāng)工作在氣模，瓦錫蘭34DF發(fā)動機(jī)已經(jīng)符合國際海事組織（IMO）Tier III的規(guī)定，沒有任何二次廢氣凈化系統(tǒng)。此外，當(dāng)由氣體燃料的硫氧化物（SOx）和CO2排放量顯著減少，并實(shí)現(xiàn)無煙操作。在液體燃料油模式，瓦錫蘭雙燃料發(fā)動機(jī)，完全符合國際海事組織（IMO）Tier II廢氣排放法規(guī)的“73/78防污公約”公約“附件六載。這個(gè)引擎可以運(yùn)作效率和經(jīng)濟(jì)上的低硫燃料（<0.1％），使得它適合在排放控制區(qū)的操作。

新獲得認(rèn)證的排放標(biāo)準(zhǔn)符合美國環(huán)境保護(hù)署（EPA）為瓦錫蘭34DF進(jìn)一步贊同這臺發(fā)動機(jī)的環(huán)保合規(guī)情況。

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.
