Obtención de la curva de consumo de un motor Chevrolet Aveo 1.6l mediante la comparación de datos entre un caudalímetro y un sensor de presión

Abstract

This work focused on obtaining the fuel consumption curve of a Chevrolet Aveo 1.6L engine by collecting data with a flowmeter and a pressure sensor to assess the performance of the engine. For the development of the tests, the Aveo 1.6 L engine was used, coupled to the Borghi & Saveri dynamometric bench, model FA-200/30 SP, which operates under the eddy current or Foucault principle. For the measurement of the fuel flow, a sensor based on the Hall effect was used, usable in Arduino or C language programming supported by a fuel pressure gauge. The results obtained show when comparing the rotational speed and minimum consumption, as fixed reference points in the consumption curve of the Aveo 1.6 engine, the smallest data error is obtained in test 2, with a margin of error of 8 .4% and 2% corresponding to the rotational speed and minimum fuel consumption, at the same time, the error results of test 3 stand out, with values of 9.2% and 11% respectively. The method applied to obtain the fuel consumption curve reached uneven error margins, in tests 2 and 3, errors close to 10% were obtained, at the same time, in tests 1 and 4 errors of 81% were obtained. and 54%. Finally, according to the results, the operation of the flow and pressure sensor allow the measurement of data close to the reality of the operation of the analyzed engine, for which it is recommended to develop a check-list process, both for the Aveo 1 engine ,6, and the dynamometric bench, to achieve repeatability and reliability of the tests carried out.
