Along with the high output of the engine, the thermal load on components in the combustion chamber may increase due to a higher brake mean effective pressure. Mechanical stress on each part may also increase due to a higher maximum pressure. For this enginer the state-of-the-art simulation technologies mentioned previously were used to achieve the same level of temperature and stress on each part as in conventional engines. MHI believes that this engine can establish a solid reputation for reliability, which has been already acclaimed in our conventional engines for the combustion chamber parts, such as rings, liners, and exhaust valves.
5. Summary
Marine diesel engines have passed through many "ages": the age of fuel consumption competition, the age of restoring reliability after excessive competition, and the age of enhancing capabilities related to the surrounding environment while maintaining reliability. Thus in each age the requirements change.
MHI continues to make utmost efforts to confidently meet such requirements so that the widest possible range ship owners and shipyard can adopt Mitsubishi UE engines.
