Repotenciación de un banco dinamométrico didáctico con la integración de un sistema de instrumentación virtual elaborado en Labview

Abstract

The present project was directed to the internal combustion engine laboratory of the Automotive Career, its objective was to repower a dynamometric bench with the integration of a virtual instrumentation system, the insertion of this instrument allowed to determine the different operating parameters of a gasoline internal combustion engine such as working temperature, RPM, power, engine torque, and specific fuel consumption. Through a preliminary field study, it was determined that the workshop had been disabled since 2016 and with technical analysis, the causes that prevented the test bench from operating were determined, such as disabled electrical installation, disconnected brake control panel, defective power supply, deficient analog measurement instrumentation, bench engine in poor condition, and deficient fuel consumption system. Once the study was completed, the equipment and its components were rehabilitated, the area was readjusted and a series of sensors were placed at the points required to perform the analysis. With LabVIEW software, the necessary programming was developed to control and monitor the different signals of each sensor and actuators; the hardware used for the control and processing was through the DAQ NI USB 6009 and ARDUINO card, to guarantee the acquisition and visualization of the information and the command in real-time. It is concluded that the virtual instrumentation is flexible for the development of automotive knowledge, because it allowed to control and monitor the processing of performance data with stability and safety of a Chevrolet AVEO 1.6 engine, obtaining as test results a minimum fuel consumption of 100 g/CV*h, with a maximum torque of 5.0 kg-m, and a maximum power of 42 hp.
