The world's first ADD30V medium speed diesel engines were produced and delivered for marine and stationary applications by Mitsui Engineering & Shipbuilding Co., Ltd. under the license of ADD Inc., Japan.This engine achieves extremely high power with B.M.E.P up to 2.7MPa and mean piston speed up to 12m/s, coupled with light weight and space saving compactness. In addition, high reliability as well as low fuel oil consumption is obtained.This paper describes the design features of principal components, such as the welded integral engine frame of steel modules, the crankshaft with cold-rolled fillets coupled with induction hardening, the piston of diffusion-bonded integral, the cylinder liner and the piston rings coated with wear-resistant ceramic, the singlevalve gas exchanging system, etc., which enable the ADD30V engine to achieve the above advantages under the extremely high power.Finally, the engine performance and the operating results are described on the basis of actual test results.
