HiMSEN, a new medium speed diesel engine family of HYUNDAl's first own design, demonstrates a PRACTICAL engine concept, offering more reliab[e power with reduced cost and more advanced design with familiar features. This new engine family consists of two base models of H21/32 and H25/33 at the moment. H21/32 has 210 mm bore and 320 mm stroke with cylinder power from 150kW to 200kW. H25/33 has 250 mm bore and 330 mm stroke with cylinder power from 240kW to 300kW.Both engine have rated speed of 720/750/900/1000 rpm and the output range is from 750kW to 2700 KW with an in-line configuration of 5 to 9 cylinders. The applications for new engines are centered primarily on the marine or land based generating sets with heavy fuel capability. Marine propulsion version and gas fuel version will soon follow.
This paper describes the design and development details of this new engine. Engine performance is described including the effects of a high stroke to bore ratio and a high compression ratio as the primary tools to meet the future ecological constraints.
Two design approach, Hi-Tech and Hi-Touch design approach, were introduced to accomplish the design target. The Hi-Tech design approach involves using modem CAE technology as a design tool for predicting engine performance and reliability. The Hi-Touch design approach enables a simple and smart design for easier production and maintenance with a minimal number of engine components, which is another key feature in enhancing the competitiveness of the new engine.
Two set of prototype engine were built to confirm of the engine performance and durability. Some test results are also presented.
