Monografia (Graduação em Engenharia Mecânica) - Instituto Federal de Educação, Ciência e Tecnologia do Amazonas, Campus Manaus Centro, Manaus, 2025.https://ri.ifam.edu.br/handle/ifam/1856Natural gas is an abundant energy source in Brazil. Its use varies across different applications, one of which is in automotive vehicles, where they are converted to run on CNG (Compressed Natural Gas) to achieve greater economy and performance, in addition to polluting less. The installation of a CNG kit in a vehicle makes vehicle inspection mandatory, an essential condition for the vehicle's legalization. According to current legislation, this inspection is a mandatory requirement immediately after the vehicle conversion and must be repeated periodically, with annual validity. This study identifies the items of CNG kits installed in automobiles that showed the highest number of non-conformities during vehicle inspections over a 6-month period at an accredited Inspection Body. This identification was carried out through the application of quality tools, such as Pareto Analysis and FMEA, thereby determining the priority criteria for potential improvements.ptEngenharia mecânicaGás natural - GNVFMEAInspeção veicularOther
