Multi-stage automatic oxygen enrichment control system for motor vehicle

Abstract

The invention discloses a multi-stage automatic oxygen enrichment control system for a motor vehicle, which comprises a supercharger, a supercharging pipe, a plurality of blocking valves, a plurality of nitrogen-oxygen separators and an air pipe; the supercharger comprises a turbine and an impeller, the air inlet of the turbine is connected with an exhaust pipe of the motor vehicle, the air inlet of the impeller communicates with the atmosphere, and the air outlet of the impeller communicates with the supercharging pipe; the blocking valves are mounted in the supercharging pipe, each blocking valve is connected with an electromagnetic switch A, and all the electromagnetic switches A are electrically connected in parallel with one relay A; the nitrogen-oxygen separators are mounted in the air pipe behind the stopping valves, each nitrogen-oxygen separator is connected with an electromagnetic switch B, and all the electromagnetic switches B are electrically connected in parallel with one relay B; both the relay A and the relay B are electrically connected with an electric control unit of the motor vehicle. The multi-stage automatic oxygen enrichment control system for the motor vehicle realizes on-demand oxygen enrichment and stage-by-stage oxygen enrichment, and solves the problem of energy waste existing in pure oxygen enrichment and the problem of insufficient power existing in single-stage oxygen enrichment.

Description

technical field [0001] The invention relates to a multi-stage oxygen-enriched automatic control device for motor vehicles, and belongs to the technical field of energy-saving and environmental protection equipment. Background technique [0002] The shortage of oil resources and more and more smog weather, people invariably attribute it to the large number of motor vehicles used in modern society, therefore, various devices for increasing the power of motor vehicles and improving and treating exhaust emissions have emerged as the times require . [0003] Increasing the power of motor vehicles generally adopts multi-injection fuel and turbocharging, and improving and treating motor vehicle exhaust generally adopts the method of three-way catalysis, but these traditional methods cannot effectively solve energy crisis and environmental problems. [0004] Oxygen-enriched combustion has become an effective method to increase engine output and reduce emissions. Oxygen enrichment ...
