The EGR system routes a number of the exhaust gases (6 ? 10%) over the EGR valve, in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they cannot burn within the combustion chamber; also, the exhaust gases take up many of the space which will rather be taken from the intake air. This reduces the level of intake air available for the combustion process during each Power Stroke; which experts claim decreases the peak combustion temperatures. This leads to lower NOx emissions. Caffeine and sugar like coffee or soda are viewed to become the common and preferable food for overnight employees because such food is able to reduce the tired feeling and help workers stay awake. However, caffeine can result in sleep disorder in the daytime, and individuals working through the night could possibly get with insomnia which causes bad eating habits.
