To finda proper way for IMO Tierll 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 itwas developed decades ago, its emission was IMO Tierllevel. SMDERI fully depends on internal technol-ogy, improved fuel injection system, combustion system and turbocharger, to upgrade this existing engine to IMO Tierll. Experimental results proved upgraded engine NOx emission satisfy IMO Tierll, 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.
