This paper deals with a new electronically controlled marine two-stroke diesel engine and TES (Thermal Efficiency System) tuning applicable to future marine carriers. Demand for prime movers for marine applications centers on the following four points:
1. Compliance with future more-stringent emission regulations;
2. Increase of Engine Output for large, high-speed vessels;
3. High thermal efficiency;
4. High reliability and safety.
As the best way of meeting this market demand, we propose application of the Mitsui-MAN B&W Electronically Controlled Diesel Engine with TES tuning. The Thermal Efficiency System is a diesel engine combined with a Turbo Generator and Turbo Compound System to increase the total thermal efficiency of the ship. The Thermal Efficiency System is an essential technique for reducing CO2 emission levels of ships.
