Abstract

The invention provides a catalyst assembly and an automobile, relates to the technical field of automobile design and solves the problem of easiness in catalyst burning-out in the conventional method for performing thermal protection on a catalyst through a catalyst estimated temperature model. The catalyst assembly comprises a temperature measuring component connected with the catalyst and a processor respectively connected with the temperature measuring component and an engine controller; when the temperature of the catalyst measured by the temperature measuring component is higher than a temperature threshold value, the processor outputs a control signal for controlling an engine to delay cutting off of fuel or increase the fuel filling amount to the engine controller. In the embodiment of the invention, the engine delays cutting off of the fuel or increases the fuel filling amount according to the control signal, so that the exhaust temperature is lowered, and further, the temperature of the catalyst is lowered. Therefore, a good protecting effect on the catalyst is realized, and the problem of easiness in catalyst burning-out in the working process is effectively solved.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a catalytic converter assembly and an automobile. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can remove carbon monoxide CO, hydrocarbons HC and NO from automobile exhaust. x Harmful gases such as carbon dioxide, water and nitrogen are converted into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The three-way catalytic converter is an indispensable and important part of the car. [0003] The operating temperature and exhaust gas temperature of domestic engines are generally high, and preventing thermal deterioration is the key to affecting the working efficiency and life of the catalytic converter. For the thermal protection of the catalytic converter, at present, it can only be enriched according to the temperature of the ...
