Abstract: The paper analyzes the existing methods for improving the fuel efficiency of reciprocating internal combustion engines, improving their operating cycle by using the energy of combustion products. Turbo-compound schemes of engines, turboelectric generators operating on exhaust gases and transmitting energy to traction motors, as well as additional engines using the heat of these gases are considered. The possibility of improving the working cycle of combined internal combustion engines with the use of an expansion machine of a rotary-lamellar type is proposed. A possible scheme of an engine with an expansion machine designed to improve the fuel efficiency of a gasoline engine of a M1 category vehicle is presented. The advantages of the proposed method of waste gas energy recovery are shown. The results of calculations and graphs demonstrating the increase in the efficiency of the power plant of the car, the scheme of joint operation of the compound expansion machine and the base engine are presented.
Keywords: combined cycle, compound, exhaust gases, heat, utilization.
