The invention discloses a fishing boat engine supercharging system which comprises a basic supercharger and a controlled supercharger. The basic supercharger comprises a basic gas compressor and a basic turbine which are meshed with each other; the controlled supercharger comprises a controlled compressor and a controlled turbine which are meshed with each other; the basic gas compressor and the controlled gas compressor are connected to an exhaust pipeline of an engine in parallel, and the basic turbine and the controlled turbine are connected to an air inlet pipe of the engine in parallel. The operation range of the engine carrying the supercharging system is provided with two low-oil-consumption areas, so that the engine can operate in the low-oil-consumption areas under the two states of free navigation and trawling operation of the trawler. 本发明公开了一种渔船发动机增压系统，包括，基本增压器、受控增压器；所述基本增压器包括相互啮合的基本压气机和基本涡轮机；所述受控增压机包括相互啮合的受控压气机和受控涡轮机；所述基本压气机和受控压气机并联在发动机的排气管路上，所述基本涡轮机和受控涡轮机并联在发动机的进气管上；搭载本发明增压系统的发动机运行范围内具备了两个低油耗区域，使
