product manual:

In recent years, with the rapid development of the automotive industry, the pollution of the atmospheric environment has become increasingly serious. The pollutant composition and concentration emitted by automobile engines are closely related to the technical status of the engine. In the tail gas of automobile emissions, there are various harmful gases and Particles, such as CO, HC, NOX, etc., affect people's lives and health, so the detection of engine exhaust temperature is of great significance for evaluating engine technology and protecting human living environment.

This product monitors the temperature of the exhaust gas emitted by the diesel engine; controls and monitors the heat storage of the selective catalytic reduction; measures the exhaust gas recirculation temperature; enables the vehicle urea to fully and selectively catalyze the reduction of nitrogen oxides, thereby achieving energy saving, The purpose of reducing emissions.
