Problems solved by technology

[0002] The problem of load response has always been an important issue that perplexes supercharged engines (especially supercharged diesel engines). In order to solve this problem, a sequential supercharging technology has emerged, but in the sequential supercharging technology, the Conversion is the fundamental problem that limits the sequential supercharging technology. If a supercharger that can reduce or eliminate the adverse effects of the turbocharger conversion process can be invented, the power performance of the engine will be effectively improved.

Abstract

The invention discloses a backflow-standby turbocharger. The turbocharger comprises a gas compressor and a turbine, wherein the gas compressor and the turbine are coaxially arranged, a control valve Ais arranged at a working medium outlet of the gas compressor, a bypass opening is formed in the communication channel between the gas compressor and the control valve A, the bypass opening communicates with a working medium inlet of the gas compressor through a control valve B, and a working medium inlet of the turbine communicates with a control valve C. The backflow-standby turbocharger can beused for effectively solving the load response problem of an engine applying the turbocharger and further improving the power performance of the engine applying the turbocharger.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a backflow standby turbocharger. Background technique [0002] The problem of load response has always been an important issue that perplexes supercharged engines (especially supercharged diesel engines). In order to solve this problem, a sequential supercharging technology has emerged, but in the sequential supercharging technology, the The conversion is the fundamental problem that limits the sequential supercharging technology. If a supercharger that can reduce or eliminate the adverse effects of the turbocharger conversion process can be invented, the dynamic performance of the engine will be effectively improved. Therefore, need to invent a kind of reverse current standby turbocharger. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: A back-flow stand-b...
