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.
