Environment-Friendly New Engine Adopted for NYK's New Car Carrier

December 16, 2003

NYK has decided to adopt a new electronically controlled engine - "8UEC60LS II-Eco" (developed by Mitsubishi Heavy Industries, Ltd.) - for its new pure car carrier (PCC), scheduled for commissioning in June 2005. This vessel, now on order to Shin Kurushima Dockyard Co., Ltd., will be able to carry 6,400 cars.

The new engine features the following characteristics:

The adoption of the electronic control system has made the flexible adjustment of timing possible concerning fuel injection and the opening/shutting of the exhaust valve. Moreover, since fuel injection pressure can be kept high even in the low revolution range, it has become possible to optimize engine performance in a broader range of operation that cannot be covered by the conventional mechanism.

1.	Low pollution : Emission of NOx will be reduced by about 15 percent compared with conventional engines. Besides, the generation of smoke and soot can be curbed.
2.	Low fuel cost : Fuel consumption can be lowered through part load compared with conventional engines.
3.	Greater reliability : Combustion in the low-load range can be enhanced. Consequently, improvement in the reliability of the combustion chamber area can be expected.
4.	Better maneuverability : Starting characteristic has been improved, enabling operation at lower speed.
