Effect of Gear shift indicator technique enhancing improved fuel economy on SUV. 2018-28-0054

Improving the fuel economy of the vehicle resulting in energy conservation on long run is a challenging task in the automotive field without compromising the emission margins. Fuel economy improvement by effective driving is the main focus of this paper by the proper utilization of gears which can enable good fuel economy even when the vehicle is driven by different drivers. GSI technique was implemented on Sports utility vehicle operating with 2.2l engine. Tests were carried with GSI and the effect of fuel consumption and emissions were compared to the regular driving cycle. Optimization of various gear shifting points were analyzed and implemented for better fuel economy keeping the drivability in mind, meeting the BS4 emission norms comfortably. The experiments were carried out in both cold and hot conditions to check the effect of GSI and positive results of fuel economy improvement was yielded. About 8% improvement in fuel consumption was yielded in cold emission and 9% improvement was observed in hot emission with the implementation of Gear Shift Indication in comparison with the regular NEDC cycle. Also significant reduction of CO2 emissions was observed.
