氮氧化物传感器 NOx Sensor 产品介绍 General Description NOx传感器是内燃机后处理系统中的关键部件,主要用于检测带尿素喷射的选择催化还原系统(SCR)的发动机尾气中的 NOx浓度,并将测量值反馈给ECU进行适当的控制以满足排放要求. The Nitrogen Oxide (NOx ) sensor is a key component in the after-treatment system ...
a simple test method for measuring NOx emission from actual vehicle operation is proposed. By analyzing the working principle of NOx sensor, the sensor installation method and calculation measurement method are determined, then the results of measuring...
(NOx) in engine exhaust, such as N2O, NO, NO2, N2O3, N2O4, and N2O5. According to the working principle, it can be divided into electrochemical, optical and other NOx sensors. Working principle: Electrochemical NOx sensor uses solid electrolyte yttria-doped zi...
Basic principle Inside the NOx sensor probe, there is a high-quality planar ceramic-based chip, which is made by HTCC (high temperature co-fired ceramic) process. The chip is integrated with heater and multi-layer ceramic components. The intelligent controller can accurately measure the content ...
Dual Mode NOx Sensor: Measuring Both the Accumulated Amount and Instantaneous Level at Low Concentrations The accumulating-type (or integrating-type) NOx sensor principle offers two operation modes to measure low levels of NOx: The direct signal gives the total... A Groß,G Beulertz,I Marr,...
Nitrogen oxygen sensor is a sensor that uses electrochemical principle to accurately measure the NOx content in automobile exhaust by measuring the current. It is mainly used in diesel engine SCR system, gasoline engine exhaust treatment system, non road mobile machinery field, power plant desul...
