The Engine and Machinery Division of Hyundai Heavy Industries Co. Ltd. (HHI) announced that it recently completed development of the sixth Hi- MSEN medium-speed engine. The newly developed H32/40V engine has successfully passed its type approval test, held at the HHI Engine Machinery Division Engine Technology Center last December. Representatives from seven of the world’s most renowned classification societies, including DNV and ABS, attended the test.

According to the company, this new engine model was developed as a response to the recent increase in demand for medium-speed engines with an output range of 6 to 10 MW. The H32/40V is said to be Korea’s first original, environmentally friendly, Veetype, medium-speed engine. It is expected to gradually increase engine sales and global market share.

The new engine has a bore x stroke of 320 x 400 mm and is available in 12-, 14-, 16-, 18- and 20-cylinder variations with power outputs of 6, 7, 8, 9 and 10 MW respectively. The engine has rated output speeds of 720 and 750 r/min. It should be noted that at rated power output, 500 kW per cylinder, the power density of 249 b.m/s and Pmax of 190 bar does not change with engine speeds. However, mean piston speed (9.6 and 10.0 m/s), BMEP (25.9 and 24.9 bar), and specific fuel oil consumption (SFOC) of 183 and 185 g/kWh do change between the 720 and 750 r/min engine speeds.

With the development of the HiMSEN H32/40V engine, in addition to the existing inline engines, HHI and the Research Institute have developed Vee-configuration engine technology. HHI expects that further application of this technology to gas engines and high-speed engines will create greater value in the global engine market.
