The amount of the land transportation is limited due to the traffic congestion and environmental pollution in Japan.<BR>In order to solve this problem, the way of the transportation is to be sifted from trucks to sea way.<BR>To realize the change, high speed vessels with light and high efficient machinery are required. Especially for the main engine, it is required maximum power with minimum weight.<BR>To cope with this requirement, the authors developed ultra high power, high speed diesel engine having the bore 320 mm, which is the largest high speed engine in the world.<BR>Advanced technology including two-stage turbocharging and Miller systems in a field of large four-stroke diesel engine are adopted in order to achieve such ultra high power.<BR>Finally, more than two times as high power as the conventional engine with the same bore could be achieved. (bmep = 2.89 MPa, mean piston speed =12.0 m/s, 700 kW/cyl, 1000 rpm.)
