Desarrollo de un tablero didáctico de los sistemas anticontaminantes: EVAP (Sistema de control evaporativo de gases), Y PCV (Sistema de ventilación positiva del cárter); para el laboratorio de la Escuela de Ingeniería Automotriz de la ESPOCH

Abstract

This research paper is aimed to create an anti contamination system didactic board called EVAP (Evaporative Emission Control System), PVC ( Positive Crankcase Ventilation System) for the Automotive Engineering School laboratory at ESPOCH. In order to achieve the main goal of the project, a bibliographical research was done to explain the most important features regarding the systems such as: parts, performance, monitoring, error codes and maintenance; gathering all this information led to a deep and appropriate knowledge of the system managing. After the bibliographical study, harmful chemical elements produced by cars that use internal combustion engines as means of power source were analyzed and their environmental impact stating the importance of the EVAP and PCV systems to control and regulate polluting emissions. As a result, it was possible to assembly the didactic board. It is important to state that all the elements found in electronically injection cars were included as well as every component of the functioning modes were simulated in the system that is the most complete and with the best applicability with the help of an electronic circuit and programming microcontrollers. Finally, this paper is an important contribution as an information source regarding elements, functioning, maintenance programs and practice for students in the Automotive Engineering major since they can use and handle the necessary tools for the diagnose and defects repair.
