Low-Cost Vibration Monitoring System for Early Fault Detection in ICE Fuel Injection Systems

The internal combustion engine (ICE) constitutes the fundamental mechanism and principal source of power within an automotive vehicle, thereby necessitating the perpetual oversight of its operational integrity. This scholarly investigation introduces a novel model that has been meticulously devised and employed for the surveillance of mechanical phenomena occurring within ICEs. This rudimentary apparatus can capture mechanical vibrations, conduct comprehensive analyses, and furnish evaluations that facilitate the identification of engine malfunctions. Lanos gasoline injection and the Toyota Hi-Lux diesel injection device were used to detect faults that occur in this system. The same device can also be applied to detect faults in many other injection systems. Data acquisition and analytical procedures were executed under standard operational parameters for these respective systems. In addition, a series of artificially induced faults was systematically introduced into these systems, and the resultant vibration signals were recorded and analyzed. A comprehensive set of experiments was subsequently carried out employing the developed apparatus to assess its efficacy in diagnosing these artificially induced faults, as well as to evaluate the device's proficiency in detecting the specified faults across these heterogeneous engine systems.
