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. Some may help some renowned tools like Tarot cards, crystal balls, runes, tea leaves, etc., while some would rather investigate the cases with all the bare hands. To these experts, the info they perceive arrive directly at mind, not through another tool. Via Psychic vision or clairvoyance, the so-called Psychic investigators try the ability of giving predictions and interpretations depending on whatever they sense beyond the physical contexts.
