新DK型ディーゼル機関の気筒数展開によるシリーズ化 Develop ment of New DK Type Engine Series by Cylinder Number Variation
The new DK series engines are developed as the next generation of engines, with 5 common concepts: environmental protection, high output with smaller engine size, high efficiency, reduction in maintenance and running cost, and increase in reliability and durability.<BR>Other than the in-line 6 and 8 cylinder types, the DK-20 model comes with 3 and 5 cylinders, and the DK 26 model with a 5 cylinder type. Development of various cylinder number types within the same model allows the new DK series to cover a wide range of output with a small engine model lineup.<BR>With the development of 3DK-20, the low output range that had been covered by high revolution engine running on marine diesel oil can now be covered by engine running on heavy diesel oil. Also, when looking at parts around the piston area, a 3 cylinder engine effectively halves the parts number compared to 6 cylinder engines with the same output. This achieves great reduction inrunning cost and maintenance costs.<BR>The follwing will introduce the new DK series engines, with details on design, performance, and benefits.
