The EGR system routes a few of the exhaust gases (6 ? 10%) through the EGR valve, back in towards the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they do not burn in the combustion chamber; also, the exhaust gases undertake a few of the space which may preferably be taken with the intake air. This reduces the quantity of intake air available for the combustion process during each Power Stroke; which decreases the peak combustion temperatures. This results in lower NOx emissions. A digital personal health record (PHR) can be a computer-based software that lets you store a variety of personal health information including illnesses, hospitalizations, encounters (i.e. visits and communications), journal information in between doctor visits, medications, allergies, immunizations, surgeries, lab results, and ancestors and family history.
