Instrumentación digital y reacondicionamiento del sistema de inyección CRDI en el banco yes01 del Laboratorio de Motores de la Carrera de Ingeniería Automotriz Sede Quito.

Abstract

In this degree work, we will expose the due protocols performed for the digital instrumentation and reconditioning of the CRDI injection system in the YES01 test bench (Hyundai Santa Fe <SM> 2006 2.0 TCI-D) belonging to the Career of Automotive Engineering. In this way, it seeks to represent a significant advance in the academic field by updating the technology and analyzing the behavior of the CDRI injection system, this system plays a crucial role in the efficiency and performance of such engines. It will be taken as a starting point the evaluation of the module status, getting to obtain the data from the test bench. In this way, the necessary repowering will be analyzed to get the truthful data without any kind of error or false data that may interfere in taking values. In addition, the level of the graphs produced by the oscilloscope will be verified and compared, thus allowing to determine the existence of any kind of noise. Once all the existing problems in the test module have been found, we will proceed to the implementation of the digital instrumentation, developing a didactic interface for monitoring the signals provided by the sensors, taking into account the analog-digital conversion since, without this conversion, it will not be possible to carry out the project. For this purpose, a microcontroller (in this case Arduino one) will be implemented in the interface, which will be used to receive the analog signals from the sensors and send the digital signals to the instrument panel. In this way, it will be possible to interpret what happens when the CRDI engine is in operation. Thanks to the interface, it is possible to pre-determine the status of the engine making the relevant diagnosis, thus avoiding inconveniences in the short or long term.
