One of the easiest ways that companies can avoid animal testing is to work with products that are actually extensively utilized in human history and still have proven their safety after a while. Companies also can depend on data from natural and synthetic substances that are already previously tested on animals. Computer modeling and databases may be used to determine biological properties of ingredients making risk assessments. 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. It is only human nature to search out some tips on something before choosing it. In fact, it shows you have some wise practice, and aren't an obsessive buyer.
