Abstract

A quick detection method for double fueled automobile steady state loading contaminant discharge, wherein, after the finish of the operating mode detection of the first fuel, the hybrid automobile fuel type selection interface is resumed automatically, thus the selection for the second fuel and its stable state loading detection can be performed rapidly, after the finish of the operating mode detection of the second fuel, the detection interface for the next automobile can be returned automatically, the two fuel detection report have the same detection serial number, after the completion of the operating mode detection of each fuel, the discharge detecting report can be printed automatically, the discharge detecting result and the detecting process data can also be stored automatically.

Description

Technical field [0001] The invention relates to a method for detecting exhaust gas pollutants of gasoline vehicles, in particular to a method for quickly detecting pollutants discharged under steady-state loading conditions of dual-fuel gasoline vehicles. Background technique [0002] At present, the technical status of the rapid detection method for pollutant emissions of dual-fuel gasoline vehicles under steady-state loading conditions is zero. [0003] Domestic pollutant emission detection for dual-fuel gasoline vehicles under steady-state loading has problems such as long detection time, low detection efficiency, cumbersome operation, and failure to meet the requirements of the detection report. Contents of the invention [0004] The purpose of the present invention is to provide a method for the detection of pollutant discharge under steady-state loading conditions of dual-fuel gasoline vehicles, which is rapid in detection, perfect in function, convenient in operatio...
