Experimental Evaluation on Fuel Economy and Emissions of a HEB

Teng-teng LI, Kong-jian QIN, Xiao-jun JING, Xiong CHEN


The working principle of a novel power-split powertrain was introduced. And then a novel power-split HEB was tested on chassis dynamometer to valid fuel economy and emission reduction. Test results showed that, this system could improve the fuel economy by 34.9%, and improve NOx emission by 23.2%, and PM by 29.4%. From the point of correction method of fuel consumption and emission, compared with Linear regression correction way, the usual correction method (1L fuel consumption =3.02g/kW.h electricity consumption) is not suitable for the correction of fuel consumption. The Linear regression correction way may be not the best method for the correction of emission.
