Abstract
Vehicle population is increasing at an alarming rate causing cities, and towns to suffer air pollution due to inefficient engines. Every year millions of vehicles are being manufactured and scrapped. Disposal or scrapping of vehicles before their useful life is not a good option. All the parts and systems of a vehicle wear out at different rates. By employing this technology of retrofit for the next 10 to 15 years, the owners will be able to contribute to society by decreasing input energy for massive automobile industries. Based on the life span of automobile parts a range of age has been found in this research at which retrofit can be carried out. In this research, cost analysis of vehicles has been carried out which shows a decrease in performance with increased maintenance, repair, and replacement cost. A mathematical model has been created for performance and cost. The minima of this mathematical model are known as retrofit age. It has been shown in this research that the time has come to adopt this technology, due to inadequate recycling of automobile parts, limited processing plants, and limited scraps yard. For this study, Honda Activa 5G, Bajaj pulsar 500, and Maruti Baleno has been considered.
