Abstract: Para la preparación de vehículos de competencia, las pruebas en la ruta o en pista sin lugar a dudas marcan los resultados reales de un trabajo realizado. Sin embargo, no se debe olvidar que en realidad los bancos de pruebas y equipos permiten cuantificar y dimensionar los trabajos de potenciación que se realice a los motores de competencia. La información que se puede recolectar de los bancos permitirá comprender qué pasos del trabajo se ejecutaron exitosamente o en que se cometió errores. Una parte del motor donde se puede trabajar para obtener un mayor rendimiento es la culata y para ello se deben considerar muchas variables. En este proyecto se abordará lo concerniente al diseño y construcción de un flujómetro de culata que permita medir los resultados del trabajo en las toberas de admisión y escape para mejoramiento del caudal de aire dentro del cilindro y expulsión de gases. Para lograrlo, se analizará mediante cálculos la mejor forma de obtener una gran masa de aire, una velocidad de entrada de aire alta, así como también una evacuación de gases muy rápida, con lo que se conseguirá que el motor respire adecuadamente incluso a altos regímenes. Este proyecto será aplicable en escenarios reales, ya que se ha encontrado que los técnicos automotrices preparan sus motores de una manera artesanal, siendo indispensable que conozcan sobre la importancia de la utilidad de este mecanismo de control, tanto a nivel académico en las facultades de ingeniería mecánica automotriz, así como también, para los mecánicos en general.
In order to prepare a competition vehicle, the actual results of a performed work are doubtless determined by tests taking place into the road and track. However, it should not be forgotten that test rigs let to quantify and measure the work done on a competition engine about power feature. The information obtained from such equipment will enable us to understand which steps of the work were successfully performed or in which ones there were mistakes. A cylinder head is a motor piece where it is possible to work in order to improve performance and there are many variables to take into consideration when such work is being executed. The design and build of a cylinder head flowmeter is discussed in this project. It will allow measuring of the results generated from the work performed by the intake and exhaust nozzles, which will show a way to improve the air flow and gas ejection. In order to achieve this goal, it will be analyzed by means of computations the best way to get a great air mass and reach a high air thrust speed as well as high gas ejection speed, which will let the engine to breath adequately even at the highest conditions of work. The results of this project will be applicable in real scenarios, because it was found that automotive technicians prepare engines in a craft manner, which makes essential that they know about how important is to take into account this control mechanism. As well as the mentioned automotive technicians, it is useful that this information also be accessible by students in automotive mechanical engineering faculties. XI A cylinder head flowmeter for the International University Automotive Mechanical Faculty lab will support the activities related to several topics that are discussed in the career’s subjects, such asμ Engine Overhaul, Internal Combustion Engines, Engine Correction, among others, being a useful tool to do comparisons, computations and measures. These features will be meaningful to study and understand engine capabilities and functions. It will be executed a demonstration in which the values generated by the tool will be compared to provider standard data. Thus, with this comparison it will be possible to verify its performance as soon as the information is analyzed, by means of statistics that may require to be checked. The project development is feasible, because the previous investigation tasks gave results that showed how the tool implementation may be executed while optimizing time and resources, without disregard of the main features that this tool must implement in order to be reliable.
