Análisis de Falla, Efectos y Criticidad del Sistema de Inyección del Motor C14ne

Nowadays it is important to develop research that will reduce pollutant emissions from vehicles, in addition to reducing fuel consumption, a point of great interest for vehicle owners. It is necessary to emphasize that the failures that are analyzed in this experiment do not generate code of fault, of there the importance of implementing this type of studies in the vehicles. Another important part about this type of analysis is that the maintenance costs of the engine are reduced, increasing the reliability and availability of the same. For development, a data acquisition card is used to obtain various motor behavior with the faults generated in the same (incorrect fuel dosing and problems in the ignition system), whichare then analyzed statistically. Later, the fault, effects and criticality modes analysis (AMFEC) is applied to determine the risk priority index (NPR), which allows to evaluate if it is necessary to intervene in the fault or the vehicle can continue to circulate without problem, since That failure does not pose a risk to the system. The results obtained demonstrate that the fault that generates a low voltage of ignition is the one that represents a greater risk for the correct operation of the system and the motor.
