Diseño e implementación de un simulador de fallas para actuadores del sistema CRDI del vehículo Chevrolet Dmax del año 2019 inyección diésel.

Abstract

In response to the growing importance of optimizing and ensuring the reliability of diesel injection systems in vehicles, this practical application project focuses on developing a failure simulator for Common Rail Direct Injection (CRDI) system actuators in the 2019 Chevrolet DMAX vehicle model. The main objective is to provide an effective tool to emulate and study controlled failure conditions in the actuators, with the aim of enhancing understanding of their behavior and ultimately improving the quality and efficiency of the system. The methodology employed in this study integrates knowledge in automotive mechanics and software programming. An integrative approach is utilized, which involves merging real vehicle operation data with specifically designed control algorithms. These algorithms enable the precise generation and regulation of failure conditions in the actuators, thereby replicating challenging situations that could arise in real-world scenarios. The results obtained from implementing the simulator are highly promising. It is feasible to simulate a variety of failures, ranging from degraded actuator response to loss of synchronization, thereby providing a deep understanding of how the CRDI system responds to adverse conditions. This knowledge can be instrumental in improving the design and programming of the actuators, as well as in formulating more precise diagnostic strategies and preventive maintenance. In terms of contributions, this research significantly advances the automotive field by providing a valuable tool for evaluating actuators under controlled failure conditions. In addition to its direct application in improving diesel injection systems, the developed simulator may have applications in training automotive technicians and in academia for researching and developing more robust control systems.
