Abstract: A compressor housing (4) having a humidification arrangement (32) configured to increase the humidity of compressed gas in a fuel cell system, a compressor housing assembly comprising the same, and a method of compressing and humidifying a gas in a fuel cell system are disclosed. The compressor housing (4) comprises an inlet portion (12) defining a compressor inlet (14) configured 2024/140782 to receive intake air, an impeller chamber portion at least partially defining an impeller chamber (18) in fluid communication with the compressor inlet (14), and an outlet portion (20) at least partially defining a compressor outlet (22) in fluid communication with the impeller chamber (18). The outlet portion (20) at least partially defines a humidification arrangement (32) configured to deliver a humidification liquid to the compressor outlet (22).

Abstract: An electrically-assisted turbocharger includes an electrically-assisted turbocharger body. A side of the electrically-assisted turbocharger body is connected to a docking pipe, a side of the docking pipe is connected to a sealing cover, a bottom of the sealing cover is fixed with a purification pipe, two ends of the purification pipe are closed, a side of the purification pipe is connected to an air intake pipe, and an inside of the purification pipe is provided with an intermittent driving element. Multiple through-holes penetrating into an inside of the sealing cover are equidistantly defined on a top surface of the inside of the purification pipe, and a filtering assembly is slidably connected to an inside of each of the multiple through-holes. The electrically-assisted turbocharger solves a problem of dust accumulation on a filter element affecting its permeability in a turbocharger in the related art.

Abstract: A variable geometry turbine device includes: a turbine casing provided with an inlet duct, and defining an exhaust port and a bypass chamber therein; a gear rotating sleeve disposed inside the bypass chamber; a rack actuator; combined nozzle guide vanes including: a fixed nozzle and an elastic nozzle mechanism; and a turbine. A first annular chamber and a second annular chamber are defined between the exhaust port and the bypass chamber. A first radial channel and a second radial channel are defined under the bypass chamber, and are connected to the first annular chamber and the second annular chamber respectively. A side of the gear rotating sleeve defines a first notch and a second notch configured to be selectively connected to the first radial channel and the second radial channel respectively; and opening and closing of the first radial channel and the second radial channel have a time difference.
