Diseño y construcción de un sistema prototipo para determinar la cilindrada total de un motor ciclo Otto por un método no invasivo mediante Labview

Abstract

Due to the growth of the fleet the state creates the pollution tax, which is generated by automobile engines, taking into account displacements greater than 1500 cm3. To address this need the design, construction and validation of a prototype system is proposed to determine the total displacement of an Otto cycle engine using a noninvasive method by Labview. The prototype system consists of a software which allows using neural networks, know the vehicle's engine and hardware, which consists of a MAF sensor, a MAP sensor, a room temperature sensor, a voltage meter of battery, filtering electronic card entry signals and data acquisition card. This system takes the signal based on the flow of air entering the intake manifold through the MAF sensor also takes cues such as depression that has the engine to start and barometric pressure through the MAP sensor, temperature environment and battery voltage when to start, these data generated when giving start are stored, before being analyzed using a neural network, which will allow to identify different types of displacements.
