The System for Adding Hydrogen-containing Gas to the Air Charge of the Spark Ignition Engine Using a Thermoelectric Generator

The article is devoted to the study of the efficiency of the system that provides the production of hydrogen-containing gas using a thermoelectric generator and the addition of this gas to the air charge of the spark ignition engine to improve its indicated, effective and environmental performance. The thermoelectric generator is installed in the engine exhaust system and provides the conversion of the exhaust gas thermal energy into electrical energy to power the generator of the hydrogen-containing gas. The results of experimental studies of indicated, effective and environmental performance of the engine with the hydrogen-containing gas added in a wide range of operating modes are provided. Vehicle fuel economy and environmental performance with the developed system for adding the hydrogen-containing gas are forecasted using a mathematical model of the car motion in the driving cycle.
