Optimization of the fuel consumption for the vehicle by increasing the efficiency of the electrical transmission system

The author studies the method of improving the fuel efficiency parameters of automobile power installation with electromechanical transmission. He also carries out the calculating research of the power installation balance during the movement of an automobile according to the NEDC – new European drive cycle. The fuel efficiency of automotive internal combustion engines remain the main indicators of his work. Among these indices, nominal and effective efficiency of the engine at a particular operating mode (often nominal), the corresponding specific fuel consumption, hourly fuel consumption in this mode, the fuel consumption on 100 km of run of the car or operational fuel consumption. Among these indicators is the most informative, operational fuel consumption, since it reflects the fuel efficiency of the power train of a car taking into account the distribution of the modes of operation of the installation in real operation conditions
