Abstract

The invention relates to an intelligent pneumatic supercharging device with the adjustable injection pressure. The intelligent pneumatic supercharging device with the adjustable injection pressure comprises a compressed air tank (4), an electronic control unit (7), a nozzle (10) and a pneumatic supercharging valve (11), wherein the nozzle (10) is arranged on the pneumatic supercharging valve (11)and faces the engine inlet direction; an outlet of the compressed air tank (4) is connected with the nozzle (10); a pressure adjusting valve (6), or a proportional electromagnetic valve, or an electric ball valve is arranged on a pipeline for connecting the compressed air tank (4) and the nozzle (10); a pressure sensor I (5) is arranged at the outlet of the compressed air tank (4); the pressure sensor I (5) and the pneumatic supercharging valve (11) are electrically connected with the electronic control unit (7); and the pressure adjusting valve (6), or the proportional electromagnetic valve,or the electric ball valve is electrically connected with the electronic control unit (7). The more-refined air inlet pressure closed-loop adjustment is realized, the optimal air inflow under the current working condition is provided for an engine, and the control quality is improved.

Description

technical field [0001] The invention relates to a supercharging device, more specifically to an intelligent pneumatic supercharging device with adjustable injection pressure, which belongs to the technical field of automobile engines. Background technique [0002] At present, the existing vehicle pneumatic supercharging device usually injects high-pressure air directly into the intake manifold through the air injection valve under specific working conditions (such as starting, rapid acceleration, etc.); at the same time, the pneumatic supercharging valve is closed to prevent the injection of high pressure The air returns to the supercharger side, and at the same time provides a closed compression chamber for the supercharger side to help quickly increase the intake pressure; when it is monitored that the working efficiency of the supercharger meets the current intake requirements, open the pneumatic booster valve and switch to the booster The normal air supply to the turboch...
