This paper takes 3 construction machinery as the research object, uses the portable emission measurer (PEMS) to test the emission in the actual operation of construction machinery. And analyzes the relationship between the operating characteristics of construction machinery and the characteristics of NOx emission and CO emission. The research results show that the NOx emission of construction machinery is positively correlated with power, and the NOx emission change rate is positively correlated with the mechanical power change rate. There is no obvious correlation between the CO emissions of construction machinery and power, and the change rate of CO emissions is positively correlated with the rate of mechanical power change.
