Design and Field Experience of Hyundai- W(a)rtsil(a) 2-stroke RT82 Family Engine
Since official shop test of proto camshaft-controlled Hyundai- W(a)rtsil(a) RTA82C engine was carried out in April 2008 at Hyundai Heavy Industries Co., Ltd.(HHI-EMD), more than 90 sets of RT82 family engine(RTA82C, RTA82T, RT-flex82C and RT-flex82T) are in service with very good service feedback, to date. Accumulated service hours of 8RTA82C engine entered in service firstly among RT82 family engine is exceeding approximately 25,000 hours. Design improvement on fuel injection and hydraulic pump system, common-rail supply system and so on was performed, through enough validation test, in order to provide economical, reliable and prolonged times between overhauls to ship owners. Through enhanced product care activities, aforementioned design modifications have been introduced accordingly on new building. Measurement of optimized engine performance, stresses and temperatures measurement of all major components for IMO Tier II emission regulations on RTA82C as well as RTA82T engines was carried out successfully, and it was confirmed that all of design philosophy met the market demands. Verification test of increased Waste Heat Recovery System( WHRS) by-pass ratio and Fuel Actuated Sacless Technology(FAST) injector was successfully performed on 7RT-flex82T engine at the test bed of HHIEMD in very close cooperation with W(a)rtsil(a) Switzerland Ltd. By above test result, ship owners can be offered more competitive and economical engine operating condition. This paper presents the latest market trend, design improvement and field experience of RT82 family engine. Also, proactive activities of HHIEMD satisfying market demand will be described.
