Abstract

In this paper, we analyzed the collected measured data of floating vehicles with mobile collection equipment in the driving of Beijing. The results show that the fuel consumption of the floating vehicle increases with the increase of the vehicle speed when the vehicle is traveling at a constant speed, and there is a significant difference between the two kinds of speed, which is consistent with the curve of the VT-Model. The fuel consumption per 100 km decreases first and then increases with the increase of the vehicle speed. There is a quadratic fit between the two kinds of speed, which is consistent with the curve of the Power-based Emission Model. PM2.5 is significantly related to instantaneous fuel consumption, but no typical function can be fitted, indicating that vehicle emission is not a decisive factor for PM2.5; the return value of pre-oxygen sensor decreases first with the increase of vehicle speed and there is a quadratic function fitting relationship between them, which also validates the concept of economic speed.
