Abstract
El sector automovilístico experimenta un ritmo de crecimiento y cambio frenético. Se
trata de un mercado en continuo movimiento donde las nuevas tecnologías juegan un
papel fundamental en su desarrollo y en su búsqueda incesante de reducir los costes
de manutención y combustible, así como las emisiones contaminantes, intentando
obtener además el mejor rendimiento y potencia posibles.
En el presente Trabajo Final de Grado se abordarán estas cuestiones buscando una
solución única. Para ello se ha optado por la adicción de un grupo turbocompresor que
ayude a alcanzar dichos objetivos sin necesidad de realizar ninguna modificación
adicional. Por lo tanto se partirá de un motor de aspiración normal al que tras analizar
su ciclo termodinámico, se le añadirá dicho grupo turbocompresor y obtener así unos
nuevos rendimientos y potencias.
Durante el documento se abordarán los estudios previos realizados así como estudios
adicionales necesarios ya que al sobrealimentar el motor se pueden presentar
anomalías en la combustión, debido al cambio de actuaciones de éste.
Se finalizará con un capítulo focalizado a las futuras líneas de estudio que podrían
complementar a este Trabajo Final de Grado, de modo que se refuercen las ideas
presentadas en él, y presentar alternativas al mercado actual.
The car sector experiences a huge rate of growth and frenetic change. This market is in continuous movement where state of the art technologies play a fundamental roll on its development. In its incessant hunt of reducing costs of maintenance and fuel, just like greenhouse gases, trying to obtain additionally better performance and power outputs. The current project deals with these questions looking for an unitary solution. For so, it has been selected the addition of a turbocharged group, which helps to achieve those objectives, without the necessity of any other additional modification. Therefore, the study will start with an atmospheric engine which after analyzing its thermodynamic cycle, it will be joined to a turbocharged group in order to obtain better performances and power outputs. Throughout the document it will deal with previous studies as well as additional necessary ones, since the addition of this turbo group may cause anomalies in the operation of the engine, in respond to these changes. Finally, there will be a chapter focused on the future lines of study which could complement this project, in order to reinforce the ideas already presented, and to host alternatives to the current market.
