The EGR system routes a few of the exhaust gases (6 ? 10%) through the EGR valve, back in towards the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they do not burn in the combustion chamber; also, the exhaust gases undertake a few of the space which may preferably be taken with the intake air. This reduces the quantity of intake air available for the combustion process during each Power Stroke; which decreases the peak combustion temperatures. This results in lower NOx emissions. The production of cost in every single trade is increasing with the frequent hikes in the fuels, electricity tariffs, new human friendly norms and new tax structures. No one can take risk to play with quality of product as it directly affects the manufacturer image. Instead every manufacturer is investing over before for making products better in terms of quality and appearance both. It seems a marathon effort to maintain the development cost within control submerging the hikes in the expense of inputs for longer period.
