Implementación de un sistema electrónico programable para controlar el avance de encendido e inyección de combustible en un vehículo de competición.

Abstract

This research is carried out be implemented in a Chevrolet Corsa Wind racing car, the work timing was controlled and any delay in the explosion of the mixture was avoided, resulting in higher power for the engine of the vehicle. A MegaSquirt programmable computer containing a (V3) version main card was used for implementing the system in the vehicle, al the electronic devices of the vehicle were switched by using 2 connectors; one of them is placed the computer and directed towards a laptop implemented with TunerStudioMS program which was modified according to air-gas relation, ignition advances, pulse with modulation and injection timing once the system was installed, different tests such as: gas emission, fuel consumption and acceleration timing were carried out: The tests were carried out before and after implementing the system. Then emission tests showed an increase of carbon dioxide, and the hydrocarbon tests a decrease of carbon dioxide and oxygen. For the tests of fuel consumption registrated an increase of 29.53% the average value of 0.816 liters of gasoline. For the tests of acceleration, it was obtained a gain of 2.56 seconds with respect to the vehicle without the implemented programmable computer. With this implementation, it was got a gain in time working the vehicle; an increasing in fuel consumption was achieved.
