A number of current technologies for internal combustion engines aimed at reducing the fuel consumption and engine noxious and greenhouse gas emissions emerge mainly due to adverse impact of transportation sector on ecology and global warming. The aim of this paper is to study the advantage in terms of fuel consumption and engine emissions, gained through the implementation of stop-start system on diesel ICE and compare the results with conventional engine. To achieve this, a short description of vehicle backward modeling is provided and simulated for NEDC, WLTP driving cycles. Simulation is done for 2 modes: conventional ICE and ICE with stop-start system. Finally, the comparative analysis is done for the results for the two modes through the tabular and graphical representation. Chevrolet Sail 2010 (1,25 L CI), equipped with 5-speed manual transmission system light duty vehicle has been chosen as a reference. Matlab/Simulink environment is used for modeling and simulation purposes.
