高出力4サイクル中速ディーゼル機関ADD30V High-Powered ADD30V Medium Speed Diesel Engine
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.<BR>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.<BR>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.<BR>Finally, the engine performance and the operating results are described on the basis of actual test results.
