Abstract: Thermoelectric generator can recover the waste heat energy from the piston aero engine exhaust gas and reduce the engine crankshaft load and fuel consumption. Based on lumped parameter method and thermal resistance analysing method, the simulation model of engine and TEG is built by using GT-POWER and calibrated with experimental data. TEG output power differences and reasons in road vehicles and airplanes are studied, the influence of altitude on TEG output power is explored and the fuel-saving effect of TEG is calculated. Result of the current research supplies theoretical and data basis for engineering application of TEG in the piston aero
engine exhaust heat recovery.

Key words: piston aero engine, thermoelectric effect, thermoelectric generator, lumped parameter method, thermal resistance analysis, generator output
