Abstract


This study evaluates the effect of the operating conditions of a single-cylinder diesel engine on the performance and efficiency of a device to generate electrical energy through the recovery of residual heat from the exhaust gases. The studied device has been formed by coupling 20 thermoelectric modules on the surface of a rectangular heat exchanger. For the analysis, three experimental variables have been selected: engine torque, rotation speed, and temperature of the coolant, which have been varied under three different conditions. The results obtained show that the increase in the engine load generated by the increase in the rotation speed and torque causes an increase in the electrical power produced. The maximum power increase is 12% and 65% by causing changes in the rotation speed and torque of the engine. Similarly, reducing the temperature of the coolant increases the energy conversion efficiency. A decrease of 5 °C in the cooling water increases the overall performance of the device by 10%. The highest level of electrical energy recovered has been 38 W, with an efficiency of 2.4%. The reduced complexity of this type of device and its high potential for improvement makes it a viable way to recover thermal energy wasted by the transport sector.
