This study aimed to establish the emission factors and inventory of agricultural machinery in Beijing 2017 under real-world operation. The emissions typical harvesters, tractors, transport vehicles, farm construction operation were tested by a portable measurement system. results showed that different modes have greater impact on tailpipe machinery. CO, NOx, HC, PM relatively stable when engine is idling moving compared excavator performing actual work. According classification standards various types machinery, perfect factor system was established, which can provide reference support for relevant research management decisions. fuel consumption Beijing, 2566.60, 1239.29, 563.08, 538.32 t, respectively. total pollutants combined harvester accounted 98%, 95%, 98% concentrations PM, Therefore, tractor, should be key control objects reduction pollution.
