MAN test 175D V12 engine

Mann (ship hangar location) diesel engine (purchasing supply) and Turbo's 175D V12 engine (purchasing supply) are currently undergoing various deployment tests and will soon be used in marine experimental projects.

         It is reported that commercial shipping is the main application area of ​​the 175D engine. Launched during the Hamburg Show in Germany in 2014, the aircraft was optimized for use in ferryboats, offshore supply vessels (ship-type shipyards), tugboats (ship-type shipyards) and workboats (ship-type shipyards) for propulsion systems (purchasing supplies) . At the same time, the machine can also be used for marine generators (purchasing supply of products).

         Currently, several engines and generator sets are operating on eight test machine tools (purchased on the product library), both in IMO Tier 2 and Tier 3 modes, with continuous durability testing exceeding 1,000 hours, and special extreme environmental tests passing through Load and overspeed running tests.

         Lex Nijsen, head of the four-stroke ship business at Mann, said, "These tests have been very successful. We are currently producing a number of engines for multiple projects and we are expected to serve a sea in Europe in the coming months. The ship delivered the first of the four machines in the series."

         It is reported that the four MAN175 engines will be used for diesel-electric propulsion. The power of a single engine is 1920 kW and 1800 r/m. The annual operation time is expected to reach 4000-5000 hours, which meets the requirements of IMO Tier 3 regulations.

         Another project is the mechanical propulsion of two MAN 175 engines for a two-body passenger ship (ship-type shipyard), each with an engine power of 2,220 kW, which will drive a fixed-pitch propeller (purchased from the product library). The catamaran will operate in Asia and will operate for 4,000 hours a year and is expected to be delivered in 2017.

         The MAN 175D engine is equipped with a common rail fuel injection system that uses an efficient MAN turbocharger (purchased from the product library) and an engine configuration control system (purchased from the product library) to meet IMO Tier 2 pollution emission requirements. The IMO Tier 3 version is compact and comes with a modular selective catalytic reduction system developed by Mann.

JIS" Stands for Japanese Industrial Standard and are published by the Japanese Standards Association (JSA) which is the equivalent of ANSI in the United States. They are created and updated by the Committee of the Japanese Industrial Standards (JISC). Like JSA to ANSI, the JISC is similar to the American Society of Mechanical Engineers (ASME).

Japan Industrial Standard is yet another option for metric sizes. Provided in JIS5K, JIS10K, JIS15K, and JISK20K pressure classes, we can offer Slip On, Blind, and Weld Neck varieties in Raised Face or Flat Face configurations. These are typically made of 316/L or A105, but as usual, all alloys are available!


Much like DIN / metric flanges, the JIS Flange specification offers a slightly wider variety of slip weld configurations for the purposes of space limitations and suitability for existing pipeline equipment. For instance, a customer can request a slip on with or without a hub as standard, or even a ring type flange, and all of this within the same B2220 specification.

JIS flanges are commonly found in exported pressure equipment and pipe assemblies from Japan. Many large ships and sea vessels which travel through international waters and service the Pacific rim will utilize equipment made to this standard, as parts and servicing for this specification are widely available.
