3 Overview

Detection system is used to measure the steady state load gasoline metering equipment dedicated pollutant emissions. Mainly used for gasoline vehicles Steady State Load exhaust gas CO, HC, CO2, NO, O2 five kinds of measured gas content. Detection system consists of the following components. vehicle exhaust detection chassis dynamometer (hereinafter referred to as bottom Disk dynamometer), pollutant gas emissions tester (hereinafter referred to as gas emissions tester), single-state test environment Yuan, computer control and data processing unit.
