The detergency of vehicle gasoline is closely related to vehicle exhaust emissions and fuel economy. In order to improve the detection efficiency of gasoline detergency and enhance the supervision ability of relevant functional departments, an on-board multi-channel rapid simulation detection (MCRSD) method of gasoline detergency was proposed. Compared with the rapid simulation detection (RSD) method of gasoline engine inlet valve deposits recommended by the regulations, the total test time for a single sample of the MCRSD method decreased by 77.8%, and the total test time for multiple samples of the method decreased by 94.4%, with 80% reduction in fuel consumption and 90% reduction in cost. The MCRSD method had a good correlation with the RSD method (Pearson correlation coefficient was 0.4-0.8), and could be used for the rapid detection of gasoline detergency. Finally, the on-site supervision and testing scheme of gasoline detergency was proposed.
