Now to the second section of the system: The nutrition (Diet, weight loss program, ect...). You can download the state diet program off of the internet. It's a PDF guide that can will give you basic rules, tips and recipes to utilize, and also for the most part the eating portion of the program is divided into 3 phases, each lasting 1 month for a total of 3 months. The EGR system routes a number of the exhaust gases (6 ? 10%) from the EGR valve, last on the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they cannot burn in the combustion chamber; also, the exhaust gases take up a number of the space which would preferably be taken with the intake air. This reduces the volume of intake air readily available for the combustion process during each Power Stroke; which in turn decreases the peak combustion temperatures. This brings about lower NOx emissions.
