The invention discloses a control method for a sequential supercharging system of a trawler, and relates to a trawler engine, only a basic supercharger is turned on when the trawler is in a free navigation state and at the left side of a boundary rotating speed N0, and a controlled supercharger is turned on once the boundary rotating speed N0 is exceeded. When the trawler is in a trawling operation state, the trawler sails at a constant low rotating speed, the borne load is increased, and when the rotating speed of an engine of the trawler is on the left side of the boundary rotating speed N0, the controlled supercharger is closed, and the basic supercharger is kept to operate normally. According to the control method provided by the invention, the controlled supercharger is controlled by controlling the engine, and the expected power required by the trawler and the engine in a trawling operation state and a free navigation state is matched with the power output by the engine in combination with the control of the gas valve and the air valve.

    本发明公开了一种用于拖网渔船相继增压系统的控制方法,涉及拖网渔船发动机,拖网渔船在自由航行状态且处于边界转速N0左边时只打开基本增压器,而一旦超过边界转速N0时则打开受控增压器。在拖网渔船处于拖网作业状态时,此时拖网渔船以一恒定的低转速航行,受到的负荷增大,此时拖网渔船发动机的转速处于边界转速N0左边时,则关闭受控增压器,留下基本增压器正常运转。本发明提出的控制方法通过控制发动机来控制受控增压器以及结合对燃气阀和空气阀的控制来对拖网渔船与发动机在拖网作业状态和自由航行状态下所需预期功率与发动机输出的功率相匹配。
