2. Q: What are the dimensions and weight of these units? How much space is required for cabin installation?
A: Take C600D6E as an example: the length is about 4318mm, the width is about 2211mm, the height is about 2060mm; the wet weight is about 5882kg. The wet weight of C800D6E is about 6300kg, and the wet weight of C1000D6ED is about 8850kg. A single-side maintenance channel (at least 800mm) needs to be reserved during installation. It is recommended that the engine room area should not be less than 15-20 square meters.
3. Q: What are the power levels and voltage options for Cummins 600-1000kW marine generators?
A: The standard configuration is 60Hz, and the emergency backup power (ESP) covers 600-1000kW. Optional voltage: 120/208V, 127/220V, 220/380V, 255/440V, 247/680V, 347/600V and other combinations. The 50Hz version can achieve 600-800kW output through the K38-DM series.
4. Q: What fuel system do these units use? What are the technical features?
A: Cummins XPI (Xtra Performance Injection) high-pressure common rail fuel system is used. Features include: injection pressure up to 2200bar, precise and controllable injection timing, more complete combustion, and lower fuel consumption. Compared with the traditional PT system, the XPI system is better in terms of emissions and fuel economy.
