The photo of the general view, the section, and the shop test performance curves of the engine are indicated in Photo 2.4.12-1, Fig. 2.4.12-1, and Fig. 2.4.12-2, respectively. The engine was delivered to a German shipyard as an exported one. The first model of the 12K50MC engine (cylinder bore： 500 mm, piston stroke： 1,370 mm, mean effective pressure： 18 bar, and output： 16,100 kw) of higher speed and shorter stroke K50MC, was completed in October, 1997. The engine was exported to Malaysia as the prime mover for the generator.
(2) Items related to NOx reduction
The protocol regarding the air pollution prevention from ships was adopted at the Conference held at Head Quarter of IMO (London) in September, 1997. As for the nitrogen oxide (NOx), the object is the diesel engine of not less than 130 kW in output which will be mounted on the ship to be built on and after January 1,2000, or the major conversion of which will be performed on and after the same day. MES has achieved the measures to reduce NOx in which the NOx limit by the IMO is cleared and the economy and reliability are not damaged on the actual ship together with the licenser.
