Abstract
This paper presents a study on the effect of engine operating conditions to meet the global emission norms and fuel economy in terms of meeting CAFE norms by in-cylinder control and after treatment systems in the exhaust. The engine thermal efficiency increases while the specific fuel consumption decreases with the increase of compression ratio (CR). The higher compression ratio results in higher peak cylinder pressure (PCP) and higher heat release rate as well as lower ignition delay. The NOx and CO2 emissions increase at higher compression ratio due to the higher peak cylinder pressure and temperature. Also PM emission is less at higher compression ratio. The in-cylinder technology and exhaust pipe after treatment systems are summarized for Emission norms EU6 and Beyond for both Gasoline and Diesel vehicle applications. With use of advanced technologies, fuel consumption and CO2 emissions are reduced by 3–5% by low friction and light weight product solutions.
