Abstract

The invention provides a vehicle engine decarburizing device capable of adjusting hydrogen and oxygen quantities according to NOx concentration change. The device comprises a vehicle engine decarburizing machine, an NOx sensor, an analog-digital converter, a central processing unit and a digital-analog converter, wherein the NOx sensor measures the concentration of NOx in vehicle engine tail gas to obtain a signal and the signal passes through the analog-digital converter, the central processing unit and the digital-analog converter in sequence; the control to an electrolytic power supply and the adjustment of the magnitude of electrolytic current are realized by the central processing unit. The invention further provides a vehicle engine decarburizing method. The device and the method control the hydrogen and oxygen yields of the hydrogen and oxygen decarburizing machine by measuring the concentration of the NOx in the tail gas, can reduce the discharge of the NOx of the engine, can improve the decarburizing effect, and protect the environment and reduce the pollution.

Description

technical field [0001] The invention relates to a carbon removal device for an automobile engine, in particular to a carbon removal device based on NO x The invention relates to an engine carbon removal device for adjusting the amount of hydrogen and oxygen by changing the concentration, and the invention also relates to the above-mentioned engine carbon removal method. Background technique [0002] Oxyhydrogen carbon removal machine is a special equipment for removing carbon deposits in automobile engines. With the increase of carbon deposits in automobile engines, it will lead to disadvantages such as poor engine start, poor acceleration, shaking, shock, high exhaust emissions, and fuel consumption. Therefore, regular maintenance of the engine and removal of negative effects caused by carbon deposits will play an important role in the normal driving of the vehicle. [0003] At present, when hydrogen and oxygen are used to decarbonize automobile engines, the output of hyd...
