The EGR system routes many of the exhaust gases (6 ? 10%) through the EGR valve, last on the Intake System, and in the end in the combustion chamber. The exhaust gases are inert i.e. they don't burn within the combustion chamber; also, the exhaust gases use up a number of the space which could preferably be taken with the intake air. This decreases the volume 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. Ringworm from the scalp presents with scaly skin where the hair had been; its as though skin could actually flake off. This requires diagnosis plus a prescription for proper medication from a physician. Once the ringworm is treated, your hair will re-grow. There is an oral medication for it as well as a shampoo.
