In order to study and analyze the operating characteristics and NOx emission characteristics of typical non-road diesel machinery under actual operating conditions, this paper takes Excavators, Loader s and Forklifts operating at construction sites as objects, the On-board Emission Test Device (OETD in short) integrating Temperature Sensors, NOx sensors, GPS and GPRS is conducted to carry out experimental tests, and a Monitoring Platform Communicating with OETD by GPRS is uesd to collect the real-time data of the machinery’s geographical location, exhaust temperature and NOx concentration. The study result shows that the Excavator and Loader in the construction site are in long-term operating conditions and the average operating time is long; during the actual operating, the NOx emission concentration of the Loader is high and the range is large, mainly concentrated at 500 ∼ 900ppm, while the NOx of Excavators and Forklifts The emission concentration is relatively low, at 400 ∼ 450ppm.
