Diseño y Construcción de un Modulo Electrónico que Controle el Ingreso de Combustible Mediante Inyectores, Implementado en un Motor Suzuki Forsa I.

Abstract

The thesis “Desing and construction of an Electronic Module to Control de Fuel Input Through Injectors, Implemented in a Zusuki Forsa I Motor” was carrried out at the Installations of the Automotive Engineering School. The purpose of this Project is adapting a programable simultaneous multipoint electronic injection system, constructing an electronic module to better adjust the fuel air mixture tending to stechiometry values, i.e. with proportions of 14,7 airs to 1 fuel, attaining a 1 value lambda. The techniques applied in the investigation consisted of the data collection through the equipment, in vehicle components with an electronic injection system; data obtained were theated with structural analysis, performing tables and graphs os sensor fuctioning displaying a procedure order for the software development to be implemented in the micro-processors. The investigation provvided as a resulta n economy of fuel which surpasses in yield the atated hypothesis at the Project beginning, reducing the fuel amount entering in to the motor correctly dosing thrrough the electro-valves each cylinder, reducing contaminant exhaust gases and having a higher power. It can be concluded that wiht the implementation of the new system the fuel consumption in the road was reduced by 14% an 11% in the city wiht a vehicle which is less contaminant of the environment. Therefore, it is recommended to keep on testing in different motor charges, cleaning the software and attain a minor fuel consumption, maintaining or increasing the power.
