Co., LTD has developed the promising environmentally friendly engines,6DE-18 and 6DE-23, which are kind to the Earth and can cope with increasingly tough environmental issues. These engines have been developed using our company's long years of accumulated technological knowledge and with three main concepts ' Ernvironmentally Friendly',' Long-Life Durability and Reliability' and ' Improvement in Safety and Assurance'. With regards to the environment, the DE Engines, while reducing NOx emissions, consume less fuel compared to our existing models and are of course compliant with IMO NOx Tier ll regulation which has been entered into force since January of2011. In addition, to comply with the Ship Recycling Convention which will go into effect in a few years, while reducing the designated hazardous materials used in engines, we are, at the same time, leading the way in management by recording those materials' classification, location and quantity. By enhancing the durability and reliability, the amount of working hours for maintenance will be reduced, it means less running cost. Then we improved combustion to keep the Lub. Oil at an appropriate condition for long term, and improved filtration to reduce combustion residuewhich causes Lub. Oil deterioration. From the perspective of improvements in assurance and safety, we implemented a full protection of high temperature areas and splash prevention of fuel oil and Lub. Oil. For labor savings during outfitting construction and installation, we concentrated the pipe connection points to the front part of the engine. Furthermore, by reducing the pip-ing and unitizing the attached equipment, we simplified the maintenance work. Both the 6DE-18 and 6DE23 satisfy either ' generator' or ' main engine' specifications. With regard to generator specifications, the6DE-18 offers a wider generator output range, making it suitable for a variety of vessel types. With respect to their ' main engine' specifications, both engines offer a 540 to 1,500 kW output range, making them suitable for work vessels and ferries, etc. This paper describes the design features of principal components, the report of on board operation and the compliance with future emission regulations.
