Engine power is proportional to the amount of air and fuel that can get into the cylinders. If we want our engine to produce more power the ultimate objective is to draw more air into the cylinder. Installing a Garrett turbocharger will increase the power and performance dramatically.
How does a turbocharger get more air into the engine?
- Ambient air passes through the air filter before entering the compressor.
- The air is then compressed which raises the air’s density.
- Many turbocharged engines have a charge air cooler(inter-cooler) that cools the compressed air to further increase its density and to increase resistance to detonation.
- After passing through the intake manifold, the air enters the engine’s cylinders, which contain a fixed maximum volume. Since the air is at an elevated density, each cylinder can contain an increased mass of air. Higher air mass flow allows a higher fuel flow rate.
- After the fuel is burned in the cylinder, it is expelled during the cylinder’s exhaust stroke into the exhaust manifold.
- The high temperature gas then continues on to the turbine. The turbine creates back-pressure on the engine which means engine exhaust pressure is higher than atmospheric pressure.
- A pressure and temperature drop occurs across the turbine, which harnesses the energy of the exhaust gas to provide the power necessary to drive the compressor.
And that is how a turbo system works. Thanks for reading, if you need to purchase a turbo please click here or call us at 800-658-5806 we are happy to answer all your questions.
