Specific phobia (also known as a simple phobia) Michael Moore?s latest movie ?Sicko? should be a wake-up call for insurance companies, the pharmaceutical industry as well as the AMA. The movie starts out showing exactly what can occur to working class Americans without medical health insurance, citing the storyline of your man who cut off the tip of two fingers in the work accident. Because he had no insurance and would be paying cash, he was given a choice of having one fingertip replaced for $12,000 or even the other for $60,000. What kind of choice could that often be? Of course, he chose to save the less costly of the two. The movie went on to exhibit the fate of a couple who had worked each of their life, bought insurance through their employers. Three cardiac arrest along with a bout of cancer left the couple bankrupt and virtually homeless despite their insurance coverage. 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.
