The assembly man-hour was greatly reduced, and the engine of the weight exceeding the crane capacity can be integratedly shipped in this system. Twenty engines can be operated annually on the existing one operation stand.

(1) New Model developed in 1997： nil
(2) Annual results of manufacture
The following engines were manufactured in 1997.
2.4.4 Daihatsu Diesel Mfg. Co., Ltd.
(1) New Model developed in 1997
1] Development of 12DK-36 type diesel engine
The photo of the general view and principal particulars of the engine are indicated in Fig. 2.4.4-1 and Table 2.4.4-1 respectively. The engine is equipped with V-type 12 cylinders, and developed focusing on the excellent reliability, excellent durability, and great extension of the maintenance interval. The environmental maintenance in the engine room was also taken into consideration, achieving the remarkably low noise and vibration level compared with those of the conventional engines. The "product friendly to the earth" is the target of the company, and this low NOx engine clears the international standards on NOx emission, and further, the fuel consumption is on the top class for this category.
This engine is the one with the maximum output in the DK series having a large number of experiences, and most suitable for not only the main engine in the marine field which is the targeted market, but also for the generator engine for the electric propulsion ship which has been extensively talked about. The engine can be served for the generator engine for the normal service of 5MW class per engine intended for South-east Asia countries. In particular, the output range can be freely selected by being provided together with the in-line type engine of the same bore in the electric propulsion ship, and in addition, simplification can be made in the aspect of controlling the spare parts because of the same bore.
2] Addition of 3-cylinder engine to DK-20 type series
As for the DK-20 type engine, 6 and 8 cylinder engines were put on the market in 1993 as the first model of the DK series, and the 5-cylinder engine was put on the market in 1996. Recently, the small auxiliary engine 3DK-20 type of 600 PS class was developed with the handy bulk carriers and Panamax bulk carriers as the target. The photo of the general view and the principal particulars of this engine are indicated in Fig. 2.4.4-2 and Table 2.4.4-2 respectively.

The engine is of 3-cylinder in-line type, coping with the extensive range of output from 500 PS to 1,740 PS with the same bore. The stable combustion with residual fuel can be realized through the 3-cylinder design compared with 6, or 8 cylinder engines of the smaller cylinder bore with same output. Excellent economy is realized by the low fuel consumption and high efficiency.
(2) Annual results of manufacture
The following marine engines of not less than 100 PS were manufactured in 1997.
