Abstract

The invention provides an adjustable composite pressure-boosting air intake system which comprises two stages of pressure boosters, that is, an adjustable pressure booster and a turbine pressure booster respectively, wherein the adjustable pressure booster comprises a first-stage compressor, an air intake bypass valve, an acceleration mechanism, a driving device and an electronic control system; the first-stage compressor is connected with the air intake bypass valve in parallel; the first-stage compressor is connected with the acceleration mechanism; the acceleration mechanism is connected with the driving device; and the driving device is connected with the electronic control system. The rotation speed of the adjustable pressure booster can be correspondingly adjusted according to the change of altitude and engine speed, so as to realize reasonable distribution of the pressure ratio of the two stages of the pressure boosters and ensure the working efficiency. Therefore, by utilizing the system, the problem of recovering the power of a variable-altitude vehicle is solved.

Description

technical field [0001] The present application relates to the technical field of compound supercharging, in particular to an adjustable compound supercharging intake system. Background technique [0002] As the altitude increases, the atmospheric pressure decreases, the air density and oxygen content decrease, and the air density in the plateau environment is significantly lower than that in the plain state. For every 1000m increase in altitude, the atmospheric pressure will drop by about 9%, and the average air temperature will drop by 6.5°C. For high-power diesel engines working in plateau areas, it will cause problems such as engine power, economy, and reliability decline. Therefore, it is very necessary to carry out research on power recovery of internal combustion engines under plateau conditions to improve the adaptability of vehicles to plateau environments. [0003] Because the supercharging technology can double the air intake density on the basis of the least cha...
