Abstract
The concentration of carbon dioxide in the atmosphere has increased significantly over the last century, largely due to human activities such as fossil fuel combustion, deforestation and industrial processes, which have led to major climate changes. The aim of this paper is to present the current state of technologies and practices for carbon capture and storage in internal combustion engines. Current technologies aim to extract CO₂ from the gases emitted from the combustion of fossil fuels, either by treating the resulting gases or by modifying the combustion process itself. Based on the information obtained, we propose to analyze in detail the current methods of carbon capture, focusing on their efficiency, associated costs and environmental effects. The analysis focuses not only on how these technologies work separately, but also on the possibility of combining them in an integrated solution, leveraging the strengths of each method depending on the field of application.
