Evaluation of the differences in determining fuel consumption for a real car based on universal and dynamic characteristics

Abstract

This paper briefly describes a methodology of developing characteristics of fuel consumption in dynamic conditions on the basis of modal measurements in road tests NEDC and FTP-75, and based on determined characteristic of fuel consumption measurement for a real car engine. The results of fuel consumption calculations determined on the basis of the dynamic characteristic for set driving conditions, and on the basis of the universal characteristic for a real car have been presented presented. The results calculated have been compared and existing differences evaluated.
