Desarrollo de un proceso de obtención de un pistón de 100 cc de 2 tiempos mediante ingeniería inversa

Abstract

This study aims to obtain a process for obtaining a two-stroke 100 CC piston applying reverse engineering from a commercial piston by using different tests such as spectrometry, hardness test, and micrography. Recycled pistons were used as raw material to produce them, contributing to the environment by reusing out-of-service pistons. On the other hand, the casting process in the sand mold has been based on previous standards and research. So that the specimen does not present anomalies such as excess porosity, fractures, etc. Since they can influence the final product. After gathering the piston, the aforementioned tests were also carried out, and a tensile test was elaborated to compare the commercial and the obtained. Prevailing that this study is based precisely on the aluminum-silicon alloys and the intermetallic phases of aluminum - iron - silicon. Furthermore, knowing how the variation of each chemical element affects the mechanical properties that make up the piston. Additionally, it provides data such as the ultimate traction effort and the yield point, and it is possible having a greater focus on the obtained product with them. It is concluded that during the casting process it is important to consider that silicon, due to the action of temperature, decreases its percentage by mass. This is an important factor since, as a chemical element, it is difficult to find it in the market. This effect is suffered by most elements resulting in variation in mechanical properties. It is recommended to elaborate additional studies with the excluded elements in this study to know which characteristics it will bring to the piston by varying its chemical content.
