Research on Upgrade of Existing Medium Speed Marine Diesel Engine for IMO Tier Ⅱ
Large amount of existing marine diesel engines in China need to be upgraded to satisfy IMO Tier II, especially for medium speed engines. To find a proper way for IMO TierII has been a critical issue for Chinese engine manufacturers. This paper introduced update design of a medium speed marine diesel engine which cylinder bore around 200mm. Since it was developed decades ago, its emission was IMO TierIlevel. SMDERI fully depends on internal technology, improved fuel injection system, combustion system and turbocharger, to upgrade this existing engine to IMO TierII. Experimental results proved upgraded engine NOx emission satisfy IMO TierII, while no negative effect on reliability, fuel consumption and manufacture cost. This update prolonged product life time of this existing engine, and proven solution could also be applied on similar diesel engine retrofit.
