The New Dual Fuel Engine 35/44 DF from MAN Diesel & Turbo SE
Due to future emission legislation for harbor as well as the upcoming IMO Tier III emission regulation for marine application and the promising development of the price for natural gas, a switch to gaseous fuels in the marine sector is a new line of conduct from customer side. Additionally ship owners develop more and more environmental awareness. With the latest development of its new medium-speed four stroke 35/44 DF engine MAN Diesel & Turbo is continuing the expansion of its product program with a dual fuel engine based on common rail technology. The paper will give an overview about the engineering of the 35/44 DF as well as the new technologies employed to fulfill the future market requirements. In addition a short overview will be given on the thermodynamical properties and expected performances for a given range of application. This new high end four stroke engine with high flexibility was developed within a very short time frame of 18 month. The development objective was a high efficiency and a high specific power output in accordance with emission limits IMO Tier II in diesel mode and IMO Tier III in gas operation with high degree of fuel flexibility (HFO, MDO, MGO and natural gas). With an output of 530kW/cyl the engine is covering a power output range from 3,2MW to 10,6MW. The 35/44 DF has the highest power output in the segment and is complementary to the power output range from current serial engine 51/60 DF from MAN Diesel & Turbo SE. This engine is based on the 32/44 CR-T2 engine, using a high level of component synergies. Therefore MAN Diesel & Turbo can also offer a retrofit solution from 32/44 CR-T2 to 35/44 DF. The prototype engine is currently running and being validated at MAN Diesel & Turbo in Augsburg, Germany and will end with a classification approval.
