Metoprolol can be an anti-hypertensive (blood pressure) drug classified like a selective beta-1 receptor blocker, also called a beta adrenergic blocker. Metoprolol is sold within the brands Lopressor and Toprol-XL and is also accessible in immediate-release and prolonged-release formulations. In addition to high blood pressure, metoprolol is prescribed to treat conditions including angina pectoris (chest pain) abnormal heart rhythms, migraine, tremors, congestive heart failure, bleeding through the esophagus, negative effects of antipsychotics, and to prevent second strokes. 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.
