The invention discloses a
turbine-pressure separation
energy storage type engine pressurization
system, and belongs to the technical field of engines. In the
turbine-pressure separation
energy storage type engine pressurization
system, a storage battery, a rectification filter circuit, a generator, a
turbine, an engine
exhaust pipe, an engine, an engine intake
pipe, an
electric drive air compressor and a
high power density direct current motor are in series connection; a
thermoelectric conversion module group adsorbs to the outer wall of the engine
exhaust pipe; an electric quantity detection module is arranged between the storage battery and a control module; an engine rotation speed sensor is arranged at the output end of the engine; an air
inlet temperature sensor and an air
inlet pressure sensor are arranged on the engine intake
pipe; the engine rotation speed sensor, the air
inlet temperature sensor and the air
inlet pressure sensor are connected with the control module; and the storage battery, the rectification filter circuit and the
high power density direct current motor are controlled through the control module. According to the turbine-pressure separation
energy storage type engine pressurization
system, the air inlet pressurization process of the engine is flexible and controllable through decoupling of the turbine and the
air compressor, the problems of turbo
lag during low rotation speed of an exhaust turbine mechanism, and blocking, surging and stalling of the
air compressor during high rotation speed of the exhaust turbine mechanism can be solved, and surplus energy of exhaust gases under whole working conditions can be utilized more sufficiently through the turbine and
temperature difference power generation.
