ABSTRACT
In resent year, the speed up of ship is advanced in the world. And, in Japan, the way of the transport is to be shifted from land transport to seaway because the amount of the land transport is limited due to the traffic congestion and environmental pollution. Therefore, the requirements of high-speed vessels with lightweight and high efficient machinery are increasing. Especially, high-speed and high power engine as the main engine is increasing also.
To cope with that requirement Niigata Engineering Co.,Ltd. had developed and supplied high-speed diesel engine, V16FX type engine and V26FX type engine, as the main engine for high-speed vessel, passenger ship, car ferry and etc.
At this time, Niigata developed V20FX type engine. V20FX has 205 mm bore and simple structure with only two high performance turbo-charger. And it was achieved mean effective pressure 2.5 MPa, mean piston speed 12.1 m/s, maximum output 250 kW/cyl. at 1650 rpm.
Key Words: Niigata FX series, V16FX, High output, High speed, Light weight
1. INTRODUCTION
In resent year, the speed up of ship is advanced in the world. And, in Japan, the way of the transport is to be shifted from land transport (ex. truck, etc.) to seaway (ex. car ferry, etc.), because the amount of the land transport is limited due to the traffic congestion and environmental pollution (ex. exhaust gas, etc.). Therefore, the requirements of high-speed vessels with lightweight and high efficient machinery are increasing. Especially, high-speed and high power engine as the main engine is increasing also.
To cope with that requirement, Niigata Engineering Co.,Ltd. had developed and supplied high-speed diesel engine. V16FX type engine since 1992 and V26FX type engine since 1995, as the main engine for high-speed vessel, passenger ship, car ferry and etc. At this time, Niigata developed V20FX type engine.
This V20FX is high-speed engine with high power, lightweight and high reliability. It was developed/designed basically from V16FX type engine for high-speed engine and Niigata's long experience, know-how, latest engine technology.
With this, Niigata finished FX series of high-speed engine for high-speed vessels. Fig.1 shows engine output range of Niigata FX series. The FX series are covered from 1545 to 7200 kW.
V20FX type engine has 205 mm bore and simple structure with only two high performance turbo-charger. And it was achieved mean effective pressure 2.5 MPa, mean piston speed 12.1 m/s maximum output 250 kW/cyl. at 1650 rpm. Table 1 shows the specification of V20FX.
This V20FX series have two model of 12 cylinders and 16 cylinders, covered 3000〜4000 kW.
