Abstract
In order to use AVL DiGas 4000 Light analyzer which can measure five gases and used for steady-state emissions testing for transient emissions testing.The delay and amplitude correction for the transient measurement of AVL analyzer based on experimental method and the PLS (Partial least squares, PLS).The concentration value of CO after being corrected and the concentration value of CO measured by VMAS sys-tem obtained a fitting equation and the slop is 0.99962.This shows very good agreement between the two.It provides an experiment and theoretical support for taking advantage of the AVL analyzer to test transient emissions.关键词
