Supercharging means forcing air into the cylinders by means of a compressor. The air at above atmospheric pressure prevails, increases its density and therefore its mass so you can burn more fuel in one volume, more power obteneniéndose the same engine. Overfeeding is particularly advantageous geographical sites higher than sea level because it compensates the loss of air density decreases with height porter cable air compressor manual. The supercharger not only to restore this loss of pressure but is able to rise to values ??above atmospheric. The superchargers used to increase pressure supercharging engines and air temperature but there is a net increase in air density. Calls are used aftercoolers or intercoolers (intercooler) to lower the temperature of air leaving the compressor porter cable air compressor manual. The power produced is directly proportional to density. The most widespread porter cable air compressor manual is called turbocharger (or simply TURBO), this increases the pressure up to 4 times the inlet pressure in one step with an efficiency up to 80%. See figure "supercharged", "supercharged supercharger" and "turbo engine cylinder pressure porter cable air compressor manual. " - Any value of the pressure above atmospheric pressure is positive pressure or pressure (boost presure in English), boost is the term applied thereafter. And any value below atmospheric pressure or negative pressure vacuum. - The intercooler can increase power output by as much as 1% (4 porter cable air compressor manual. A minimum of a 1% increase in the power rankings for every 10 degrees (5. 56 K) temperature reduction can be anticipated. - Today you can go fast in a Mazda Miata and get four times the mileage per gallon achieved by an engine without boost porter cable air compressor manual. - The loaded motor works perfectly well knew with what camshaft call "economic" or stock. Low overlap, short duration cams, low-profile (low-lift cams) all work well with the Chargers knew. - The opening pressure valve called wastgate "at which it begins to rise from his seat is generally ½ to 1 / 3 maximum boost pressure porter cable air compressor manual. . . porter cable air compressor manual.
