mjd combustion

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 clear the two perspectives will certainly draw swords against the other quite often. Although many people agree that efficient markets are best for everyone, the steps that government have to take to obtain there often run counter for the microeconomic interests of business. Sometimes a merger should be blocked to foster competition. Sometimes disclosures must be legislated to ensure clientele may make informed decisions. And sometimes certain activities must be regulated or prohibited so that some usually are not financially harmed by others.
