Desarrollo de un sistema de recuperación de energía de los gases de escape mediante un turbo generador en un motor de combustión interna de 4 cilindros a gasolina.

Abstract

The development of an energy recovery system which was implemented on the Chevrolet Swift engine, by means of a turbo-generator has the purpose of making the most of the heat energy produced by the engine, for through a proper conversion of energy, be able to produce energy power which can be stored in an accumulator. The technical diagnosis of the engine determined lack of important parts that must be replaced for the proper operation of the test bed. After the missing parts were implemented a study selection, design and simulation of critical parts was developed which incorporates each of the modified systems. The supercharging system comprises a turbocharger, an intercooler, air ducts and pipes for internal lubrication of the turbocharger. The energy-recovered consists of the following parts: a fixed geometry turbocharger, responsible for supercharging the engine, an electric generator to convert the mechanical energy from the turbocharger into power, a tension control unit responsible to rectify voltage generated and an electronic control unit which monitors all the behavior of the internal combustion engine. It was demonstrated that speeding up the engine gradually it increases the air charge submitted by the turbocharger, having a greater flow of gas at the outlet of the exhaust manifold, so that the effect “turbolag” present in the turbocharger expires; and the mechanical energy of rotation is converted towards the electric generator producing electricity.
