Gasoline vehicle steady-state emission testing system

The gasoline vehicle steady-state loading condition emission testing system uses a chassis dynamometer to simulate road driving conditions, and an exhaust gas analyzer to analyze the emission of pollutants in real time under specified conditions. A computer control system automatically determines whether the vehicle's emissions meet standards.

This system uses the same chassis dynamometer as the simplified transient condition emission testing system.

The exhaust gas analyzer is a dedicated model for SAM condition testing, capable of detecting the levels of CO, HC, NO, CO2, and O2 in vehicle exhaust emissions, and can also detect the vehicle's engine speed.
