The article deals with the problem associated with increasing the efficiency of operation of a spark ignition engine. Among the alternative fuels for spark ignition engines, ethanol is regarded worldwide as an important renewable energy source Adding ethanol to commercial gasoline reduces harmful air pollutants, greenhouse gases, and production costs. On the other hand, the use of benzoethanol mixtures as a fuel is associated with a lower saturated vapor pressure, which makes starting a cold engine quite difficult, and also leads to deterioration in the fuel-economic and environmental performance of the engine in the warm-up mode. A device with the use of thermoelectric modules is proposed for maintaining the optimal air temperature at the intake of a spark-ignition engine when operating on benzoethanol mixtures in the start-up and warm-up modes of a cold engine. The description of the proposed thermoelectric device, the principle of its functioning and the results of functional tests are presented.
