Turbocharger Origin Although today we talk a lot about turbocharger engines, they aren´t a product of new technology as new as it seems. The process of turbocharging has its history linked to aviation. With a pressure bigger than the atmospheric in the cilynders, compensated the problem in air rarity in great altitudes. Joined with this, the engine increased its power too, that later became another resource for racing cars in the 30s. Nowadays, acclaimed as a developed version of the common engine, of natural aspiration, gradually the turbocharged engines became part of light and heavy engines industry, as for example: engines for heavy trucks, trucks, cars, boats, etc... Turbocharger Description The turbocharger is compound of a centrifugal air compressor, directly linked to a centriped turbine. The compressor and turbine wheel are linked to an axle supported by floating bearings, lodged in a bearing housing. The centripetal turbine is composed by a cast iron housing and wheel. The bearing housing incorpores the compressor back plate, heat plate, bearing safe rings, bearings, thrust bearings, centrifugal collar, piston rings and seal ring. Turbocharger Operating Procedures From all the energy power produced by inward combustion engine, only one third is used to move the engine, another third disappears in the air cooling system and the third left wastes as exhaust gas. The turbocharger uses the energy produced by expansion of these gases to rotate the turbine wheel, which reaches rotations from 3.000 to 130.000 RPM. Joined by a common axle to the compressor wheel, that rotates at the same speed, aspiring the air from the filter and compressing through the compressor housing to the cilynder interior. Turbo Components and Their Functions 1 - Compressor Housing and Compressos Wheel: The centrifugal air compressor has the function to arpire the atmosferic air and compress it to the cilynder interior, reaching three times the atmosferic pressure. 2 - Bearing Housing: Gets lubricant oil from the engine and serves as sustance to the turbine ans compressor wheel which floats on thrust bearings. 3 - Turbine Wheel and Turbine Housing: the centripetal turbo is started by heat energy from exhaust gas ans it has the function to impel the centrifugal compressor. Turbocharger Function The turbocharger function is to provide a bigger air volume to the engine, making possible a perfect fuel burning and a better performance. Turbocharged Engine: A turbo engine, as receive compressed oxygen through the compressor of the turbocharger, works as the sea level as in altitudes, with 100% of volumetric capacity. Aspired Engine: An aspired engine loses each 1.000m over the sea level, 10% of its power. Added its natural fault, it would be in 1.000m of altitude, o loss of 30%. Benefits Obtained with a Turbocharger More Power: Adding more quantity of air in the cilynder, the engine can burn a bigger volume of fuel automatically and it has an increase of power, which changes around + or - 20%. Less Fuel Consumption: The fuel quantity consumed by a turbo engine is around 10% less than a naturally aspired. Smoke Elimination: A turbo engine is basically a clean engine. Disposing a bigger volume of air in the cilynder, assures a perfect burning of exhaust gas, avoiding the fuel waste and eliminating the smoke. •  Technical Information
