This project consists in the research of a way on improving the efficiency of gasoline engines. To achieve this goal the project will be focused in the ignition system, because the actual system only gives control on the moment the burn starts, but not to what happens while the fuel is burning, so the objective is look for a way of ignition that is completely capable of controlling the burnt in the combustion chamber. By achieving this goal, the efficiency of the burnt in the engine would be increased, and also the emissions would be more stable. In order to achieve the objective of the project, the Corona Discharge effect has been considered in order to apply it as an alternative spark plug for the engine. By having assumed this technology as the one chosen to improve the ignition, in order to achieve this project’s goals a wide research of the actual state of art of corona discharge and how to control it has been done. The project will look at all the actual research completed regarding alternative ignition systems, investigating how the spark is generated in each of them and how they are controlled. After all the research, an investigation is made in the Corona Discharge generation, finalizing with an ignition system modification to allow the implementation of this effect in conventional engines.
