![]() ![]() The exhaust gases can rotate the turbine rotor up to 30 times the engine speed.ģ] The compressor and turbine of the turbocharger have a common shaft thus the rotor of the compressor also starts to rotate along with the turbine rotor.Ĥ] As the compressor starts to rotate, it draws clean air from the air filter at atmospheric pressure and compresses it above the atmospheric pressure to increase its density.ĥ] Due to the compression, the temperature of the air gets increases thus after compression the air is passed through the intercooler to lower the temperature of the air.Ħ] Then this highly compressed air is fed into the intake manifold of the engine.ħ] The turbocharger also uses a waste-gate to bypass the exhaust gases at higher engine speed.Īt higher engine speed, the higher flow of exhaust gases can Overspeed the turbocharger thus it can damage the turbocharger and engine components. The scroll of the casing directs the exhaust gases flow over the turbine blades.Ģ] Here the exhaust gases lose some amount of energy to rotate the turbine rotor. The turbocharger works as follows to boost the engine:-ġ] As shown in the above figure, the exhaust gases from the engine enter the casing of the turbine. Both compressor and turbine are mounted on the same shaft thus the power developed by the turbine is used to run the compressor. The turbocharger comprises two different components in a single unit which is the turbine and the compressor. Thus it helps to recover the energy from the exhaust gases and increases the overall efficiency of the engine. It uses the kinetic energy of the exhaust gases to run the compressor. Like a supercharger, it never uses the power of the crankshaft to run the compressor. Thus the turbocharger helps to increase the power developed by the engine and to enhance its performance. Then by supplying more fuel the engine develops a higher amount of power. It feeds compressed air into the cylinder thus it increases the amount of O₂ molecules fed to the engine. ![]() A turbocharger is a turbine-driven compressor that recovers energy from the exhaust gas and utilizes it to power a compressor that delivers additional compressed air into the combustion chamber of the engine. Thus the engine can burn extra fuel and develop more power than the same sized naturally aspirated engine. Turbocharging is the process of increasing the power output of the IC engine by forcing the extra compressed air into the intake manifold of the engine with the help of a turbocharger that runs on the kinetic energy of the exhaust gases. ![]()
