Adquisición de parámetros para pruebas en motores de combustión interna en la Universidad Técnica de Ambato para prácticas de laboratorio de los estudiantes de la Carrera de Ingeniería Mecánica

Abstract

The present technical project is based on the implementation of sensors for the acquisition of operating parameters in the internal combustion engine test bench at the Laboratories of Mechanical Engineering. A human-machine interface will also be developed for the real-time monitoring of the variables read and calculated, depending on the engine operating parameters. Once the acquisition system is implemented, a number of test are performed in order to obtain the characteristic curves of the engine, such as Torque vs Speed, Brake power vs Speed, Consumption vs Brake power, Volumetric efficiency vs Speed. A procedure is developed in order to assure that the stationary state is reached, and therefore the measured data is free from transitory effects. The obtained curves positively compare whit those provided by the manufacturer.
