Abstract. The authors study the method of improving the fuel efficiency parameters of automobile power installation with electromechanical transmission. They also carry 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 their 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 powertrain of a car taking into account the distribution of the modes of operation of the installation in real operation conditions.
The specified calculation was carried out for the efficiency of the electric powertrain, equal to 0.95. But it should be noted that such transmission involves the use of modern highefficiency electric generator and the electric motor, the control unit carries out the relationship between them by using digital control of frequency and power, which reduces the losses in the electric part of the powertrain. For lower values of transmission efficiency, the fuel consumption of the vehicle increases proportionally track. It should be noted that electromechanical transmission has the prospect to further reduce fuel consumption by the engine. When using a storage element (battery or supercapacitor) in recupe-radios, braking energy becomes possible to optimize the operation of the internal combustion engine not only on speed but also on the load.
Key words: power installation, automobile, internal combustion engine, electromechanical transmission, new European drive cycle, fuel economy, exhaust gases emissions.
