NOVELTY - The method involves heating exhaust gases by a turbocompressor (18) when a positive ignition thermal engine (10) functions at less load, where the turbocompressor includes a turbine (25) and a compressor (17). The exhaust gases are compressed and heated by the turbine. An operation of the turbocompressor is reversed at less loads, where an usual inlet (16) of the compressor is taken as an outlet and an usual outlet (21) of the compressor is taken as an inlet. A usual inlet (24) of the turbine is taken as an outlet and an usual outlet (27) of the turbine is taken as an inlet.    USE - Method for increasing temperature of exhaust gases of a positive ignition thermal engine of a vehicle.    ADVANTAGE - The method enables increasing the temperature of the exhaust gases at less loads so as to use thermal energy of the exhaust gases according to a Rankine cycle even at less load. The method enables actuating the turbine by the exhaust gases when the turbocompressor starts working at strong loads so as to yield kinetic energy, so that the turbine actuating the compressor compresses intake air, thus ensuring better filling of the cylinders, and hence producing better output. The method enables reducing precious metal content of the three-way catalyst via faster actuation of the catalyst. The method enables allowing a turbocharger on a number of motor current so as to increase the gain of the Rankine cycle consumption under real conditions.
