Замкнутая система управления нейтрализацией отработавших газов автомобилей

Abstract

Purpose: The most common methods of neutralizing harmful car emissions are based on catalytic neutralization. It has been shown that the catalyst should be heated up. However, the available papers have never discussed possible systems of control over the catalyst temperature according to the harmful emission minimization criterion. This paper discusses a new neutralization mode based on catalyst temperature control (regulation, stabilization). Results: Analyzing the factors which affect the catalysis effectiveness shows that the catalytic properties are better when the catalyst is heated up. A structure was developed for local and global automated closed systems which control the neutralization process by heating up the catalyst only in the moments when the concentration of the harmful exhaust gases is high. These control systems with an operator (driver) also allow us to trace the neutralization process. The exhaust gas concentration functionally depends on the catalyst temperature in such a way that using a closed system of temperature control will help to reach the required standards. Practical relevance: The proposed method can considerably decrease the harmful car exhaust emissions. The results of this research can be a foundation for developing hardware and software technological solutions for controlled catalytic converters and their subsequent introduction into the automotive industry.
