Another presentation from AutoTech Labs – The Turbocharger.A device which uses the exhaust gas energy to supply more air to the engine.The presentation takes you to a detailed explanation on how turbocharger component works with the engine.A turbocharger is made up of two main sections: the turbine and the compressor.
The turbine consists of the turbine wheel and the turbine housing.In naturally aspirated piston engines, intake gases are drawn or “pushed” into the engine by atmospheric pressure filling the volumetric void caused by the downward stroke of the piston which creates a low-pressure area, similar to drawing liquid using a syringe. Watch the video from Autotechlabs for more info:
The amount of air actually inspired, compared with the theoretical amount if the engine could maintain atmospheric pressure, is called volumetric efficiency.The objective of a turbocharger is to improve an engine’s volumetric efficiency by increasing density of the intake gas (usually air) allowing more power per engine cycle.
The turbocharger’s compressor draws in ambient air and compresses it before it enters into the intake manifold at increased pressure.This results in a greater mass of air entering the cylinders on each intake stroke. The power needed to spin the centrifugal compressor is derived from the kinetic energy of the engine’s exhaust gases.//wikipedia
