Practical investigation and evaluation of the Start/Stop system's impact on the engine's fuel use, noise output, and pollutant emissions

Abstract

Prior to the emergence of alternative energy sources, research on the start-stop system, which shuts down the engine at idle, was rapidly conducted by car manufacturers, in parallel with the growing need for energy-efficient technologies and the tightening of environmental regulations for vehicles. In addition, in order to increase sales as well as convenience and fuel efficiency, car manufacturers are attempting to commercialize start-stop technology by merging it with the generic smart key system. This paper shows a new practical study to evaluate a start/stop system designed specifically for the job. We have built and implemented a complete electronic start-stop mechanism for an aftermarket smart key system that uses an ECU starter and OBD-II interface. In addition to meeting all specified response time thresholds for vehicle status requests, the implemented Start Stop system standardizes the interface with vehicles to reduce the time required to install the Start Stop system on various vehicles. The results of this study highlight the importance of the resting system in terms of reducing fuel consumption, limiting greenhouse gas emissions, and keeping the vehicle engine quiet.
