Implementación de un sistema de inyección programable con distribución variable y encendido semi secuencial en el Motor Fiat evo fire 1400 cc del laboratorio de inyección electrónica de la carrera de Ingeniería Automotriz

Abstract

The Automotive Engineering School has owned an engine system Fiat Evo Fire 1400 cc with variable valve timing for a long time. It was disable because it did not have most of its components. Therefore, this work aimed to run it by incorporating a programmable injection system. To run it correctly, each sensor and actuator selected for the engine were set up and calibrated. Hence, Haltech Sprint 500 computer was chosen since it is 100% compatible with all the engine features. Its main feature is that it is possible to modify any parameter of the engine running in real time, so it is guaranteed that sensors and actuators work according to the engine needs. It was possible to interact easily with each one of the ECU maps, graphs, and bars, setting it up correctly. Teachers will have the opportunity to teach their classes related to programmable injection in a better way, since with this test bench, students will be more familiar with this type of systems focusing on hands-on work rather than theory. The Haltech Sprint 500 computer was installed setting up each one of the main parameters of the engine running, based on technical data taken from the engine manual to get optimal outcomes. The Haltech Sprint 500 computer is the key element of a programmable injection. Therefore, the procedure described in the installation manual has to be followed to avoid damages, since high voltage or short circuit might burn it, which would be a meaningful loss.
