Research on Diesel Engine Energy Saving and Emission Reduction Based on Air System and NOx Virtual Sensor ModelDOI: 10.4236/oalib.1104597, PP. 1-9 Subject Areas: Mechanical Engineering Keywords: Diesel Air System, Exhaust Gas Recirculation, Variable Geometry Cross-Section Turbocharged, Virtual Sensor Abstract
As of the beginning of 2017, the number of motor
vehicles in our country exceeded 300 million. Motor vehicle emissions are one
of the most important sources of atmospheric haze. Therefore, vehicle emissions
and energy consumption have always been important research directions for
emission reduction and energy saving. In this paper, IOC (intake oxygen
concentration) observer and feedforward controller of EGR and VGT are designed
based on diesel engine air model. NOx virtual sensor model is designed to
detect NOx emission as the feedback variable of IOC observer, and achieve the purpose of accurately
measuring the amount of NOx, controlling the EGR valve and the VGT blade in
real time, reducing the NOx emission of various diesel engines, improving the
fuel economy of the engine and reducing the source of the haze, and there is an
important reality in this research and the later promotion and social
significance.
