Development of a process for obtaining a two-stroke 100cc piston by means

Abstract

Introduction. In our country, there is a lack of spare supply, in particular for motorcycle engine stroke pistons, since the production of this element only occurs in countries such as: Germany, Argentina, Spain, Turkey, Great Britain, and the United States, Brazil, Japan, China and India, these being the pioneers that supply the replacement stock both worldwide and in Latin America. Objective. Obtain a process for obtaining a two-stroke 100 CC piston by applying reverse engineering from a commercial piston through the use of different tests such as: spectrometry, hardness test and micrography. Methodology. To obtain it, it has been made from recycled pistons as a source of raw material, also contributing to the environment by reusing pistons that are out of service, on the other hand, for the sand mold casting process It has based on standards and previous research to reduce effects such as excess porosity, fractures, etc., since they can influence the final product. After this, after obtaining the piston, by means of the aforementioned tests, a comparison is made between the obtained and the original, additionally with a tensile test, providing data such as the ultimate tensile stress and the yield point. Results. In this way, a functional piston was obtained, and it is concluded that during casting it is important to consider that silicon by the action of temperature decreases its percentage by mass, an important factor since as a chemical element it is difficult to find in the market.
