MAN Diesel & Turbo Debuts New High-Speed Engine

Posted by Irina Tabakina

MAN Diesel & Turbo created a stir at SMM on the high-speed market with its service concept for the MAN 175D high speed engine. With the MAN 12V175D, MAN Diesel & Turbo is presenting the first cylinder version of its new high-speed engine family. The twelve-cylinder model, developed especially for use in the shipping industry, is part of a product initiative aimed at providing MAN customers with a product portfolio that covers every power requirement, from high to low speed.
“With the MAN 175D, we are supplementing and completing MAN Diesel & Turbo’s and MAN Truck & Bus’s product portfolio in the maritime sector,” said Dr. Hans-Otto Jeske, CTO and acting CEO for MAN Diesel & Turbo. The new engine will be offered with an output spectrum from 1,500 to 2,200 kW and will be available to the first pilot customers from as early as 2015.
The MAN 175D was designed from a clean sheet incorporating the latest in engine technology, and as a natural consequence eco-friendliness was high on the agenda. The engine sports a compact and modular exhaust gas after-treatment system using the selective catalytic reduction (SCR) method, and the engine will satisfy the strict environmental standards of the IMO Tier III.
“The decision was taken (about 5 years ago) to introduce this new line of engines,” said Klaus Deleroi, senior vice president, head of the MAN Diesel & Turbo Medium Speed business unit, interviewed at the MAN booth at SMM 2014. “There were two reasons for that: first, this fills a gap in our power range portfolio; second, many customers came to us and requested another competitive player in this range. They were asking: ‘why is MAN, as one of the inventors of the diesel engine, not present in this engine range.”
According to Deleroi, two engines are currently running on the MAN test bench, with a cumulative of 500 to 700 hours under their belt.
“We had the advantage to start from a clean sheet, and we were able to integrate all of the recent technologies and advantages. So the key points are this is more powerful, per cylinder (than a popular competitive brand) and it is more fuel efficient.”
“If you compare it power to power, this engine is smaller. Where you might have to install a 20V, you can install a 16V of this engine. This engine will be available in a 12, 16 and 20V.”
While the new engine will be sold into a variety of applications, starting with the patrol boat and yacht sector, it is clear that the company is targeting the demanding workboat market where owners clock upwards of 4,000 hours annually.
