The EGR system routes a number of the exhaust gases (6 ? 10%) through the EGR valve, back in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they do not burn inside the combustion chamber; also, the exhaust gases occupy a few of the space which may otherwise be taken from the intake air. This cuts down on level of intake air readily available for the combustion process during each Power Stroke; which often decreases the peak combustion temperatures. This ends in lower NOx emissions. As any first-year econ student will advise you, there's 2 disciplines in economics - microeconomics and macroeconomics. And they don't like the other. As the U.S. Congress prepares to lower the hammer for the financial services industry, consider the forces which are butting heads and why it is just seeing that they've thought we would do this. Microeconomics may be the area that business students gravitate towards. Profit maximization could be the mantra, with marginal costs and fixed costs optimized to generate businesses as much money as possible. Microeconomics compares the world with the eyes of the CEO, who looks to accomplish what's best for his company - bring in more money and deliver value.
