The adults were fat, the children were fat! They just laid around all day consuming doing no exercise what so ever and to quote the captain, "Computer, define dancing". The EGR system routes a number of the exhaust gases (6 ? 10%) through the EGR valve, back in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they do not burn inside the combustion chamber; also, the exhaust gases occupy a few of the space which may otherwise be taken from the intake air. This cuts down on level of intake air readily available for the combustion process during each Power Stroke; which often decreases the peak combustion temperatures. This ends in lower NOx emissions. The world has limited resources and that we all know this, but we rarely stop and think how many products we use and whether we actually need them. Iron, metal, coal and every other natural recourse on the planet will come to an end one day as well as the need for the hour is to conserve as much of these even as can.
