二、关联题(关联题题干下有4个小题,每小题4个选项)

  The clearly visible benefit of RT-flex engines is their smokeless operation at all ship speeds. This is achieved by the superior combustion performance with the common-rail fuel injection.
  This system maintains the fuel injection pressure at the optimum level right across the engine speed range, ensuring optimum combustion under all operating conditions. In addition, a selective shut-off of single injectors at very low speeds and an optimized exhaust valve timing help to keep smoke emissions below the visible limit.
  Sulzer RT-flex engines also have the advantage of steady running at lower speeds than engines with mechanically-controlled injection. They can run very steadily, and without smoking, at 10-12% of nominal speed, which for the RT-flex 60C is about 10-14rpm. This is made possible by the precise control of injection, together with the higher injection pressures achieved at low speed, and the sequential shut-off injectors.
