Detección de fallos en un motor de encendido provocado mediante el análisis de la presión de los cilindros con el uso de un transductor de presión en el Distrito Metropolitano de Quito

Abstract

In order to develop an experimental technique in the automotive field, since the traditional diagnostic system can be affected by various factors such as physical, chemical, among others, this study focuses on performing a diagnostic technique, without the need to intervene directly in the mechanical systems of the internal combustion engine, In such a way that it is achieved by means of the internal pressure of the cylinder, with the help of a transducer connected to an automotive oscilloscope, giving as a product, the transformation of air compression signals measured by the sensor, inside the engine, transformed into voltages, thus achieving the analysis of each of the phases except the explosion. These oscillograms will be subjected to comparison with a standard engine and in optimal operating conditions, causing problems to determine the failures that may occur indirectly in the engine, in order to determine the area of failure, in the oscillograms we will observe the four phases of the combustion engine, but mainly three of them will be analyzed, since the study will be carried out at the moment of starting the engine, in each phase will be compared, so that, if an anomaly is observed, it will be focused on the components that make up that phase reducing the diagnostic time and without the need to manipulate the engine.
