Abstract

The invention discloses a double-channel turbine bypass bleeding device which comprises a turbine volute, wherein the turbine volute is provided with two inlet channels, the two inlet channels are respectively communicated with a bleeding channel, the outlets of the two bleeding channels are provided with concave valve bases, the concave valve bases are provided with a shared valve cover, and the valve cover and the concave valve base form a slip connection, so that the characteristic curve of the flow of valves and the flow area of the valves almost changes linearly. By using rack-and-pinion transmission, the accurate control on the opening and the flow area of the valves can be realized. Thus, the invention can accurately control the amount of bypass waste gas, thereby realizing the optimum matching of a pressure booster and an engine.

Description

technical field [0001] The invention relates to a waste gas bypass device of a turbocharger, in particular to a double-channel turbine bypass exhaust device for dual-channel simultaneous discharge of a dual-channel turbine. Background technique [0002] For vehicle engines, in order to solve the performance problem of low working conditions, the high working condition bleed configuration is mostly used. At this time, the design of the turbocharger is to make the engine performance below the middle speed to obtain the maximum torque, that is, the supercharger and the diesel engine are matched according to the maximum torque condition. When the engine rotates at a high speed, in order to limit the boost pressure, the maximum explosion pressure and the speed of the supercharger within the allowable range, part of the exhaust or part of the supercharged air of the engine is discharged through the purge valve, so that the supercharger A section of the operating line of the compr...
