Análisis del diseño y construcción del múltiple de admisión y escape en el torque y potencia de un motor ciclo Otto de 1100cc, mediante un software CFD y su validación experimental.

Abstract

The following investigations Project was establishing the different technical characteristics of the thermodynamic behavior of the engine under analysis are established, using calculation as and software simulation; analytically determining the processes and thermal cycles of engine operation, as well as also the analysis consideration for the design of the intake and exhaust manifolds. At the same time, the different aspects and physical parameters of the intake and exhaust manifolds are studied, and how they influence the thermodynamic behavior of the engine, such as its dimensions, material, geometry, etc. as well as it will determine the different pressures to which the collectors are subject and in general the character of flow within the manifolds. The different distributions of pressures and velocities of entry and exit within the multiples are determined by means of a computational fluid analysis, where the use of this very ºpotential tool can be observed virtually the general behavior of the flow, being able to determine for the intake manifolds and escape pressure losses, velocities, temperatures, densities, among others and subsequently with these result the power loss is determined by the relationship in the thermodynamic calculation of the engine, leaving as precedents the characteristics and the values suitable for the geometric consideration and analytical design of intake and exhaust manifolds. It provides power and torque improvements for the exhaust manifolds are determined that the geometric considerations that is generally raised in our environment can provide the increase in power and torque, resulting in our proposed redesign provides improvements in all aspects.
