Desarrollo de un sistema mínimamente invasivo para determinar los valores de presión de compresión de un motor diésel CRDI 2.0.

Abstract

The project develops a minimally intrusive system to measure compression pressure in CRDI 2.0 diesel engines by analyzing the current consumption of the starter motor. Traditional methods were investigated, and an experimental methodology was applied with a DOE to record data from injection system sensors and an ammeter clamp, using a DAQ card. The signals are processed with LabVIEW and statistical software, correlating electrical data with actual pressure using statistical techniques. The system has an 81.30% accuracy, a 10% error and a maximum deviation of 16.20 psi, diagnosing in 10 minutes without disassembling components.
