Abstract

The experiment performed was to determine air flow, velocity, pressure and turbulence through an adaptor plate between a 2-barrel carburetor and a 4-barrel intake manifold. We first created the part using SolidWorks making sure to include 2 body parts that allowed a smooth transition of air through the intake. We then uploaded an assembly instead of a singular part to ANSYS to ensure the airflow read was accurate, as well as added groves to improve the mixture of air and fuel. Computational Fluid Dynamics (CFD) module was applied through Fluent Fluid. Three-dimensional Finite Element Analysis approach was applied to the three-dimensional meshed geometry. This universal carburetor adapter plate will allow for a perfect mixture of air and fuel in order to burn in the cylinders present in the car. This helps improve combustion. The main function of our part is to improve the mixture of air and fuel to allow for better combustion. We added an air intake with the velocity 0.25 m/s. Which was pushed through the top of our adaptor plate and mixed with fuel to then be spewed out through the bottoms which in a car would allow for the burning of cylinders to begin. Numerical analysis performed that the velocity showed to travel further down the object with grooves than the object without. When analyzing pressure, we saw that the highest pressure was greater in the object with no grooves whereas the object with groves had a much lower pressure.
