Turbochargers are known for the increased power and performance they can give to your vehicle. They use the exhaust gases which are a byproduct of the engine combustion and in turn push more air into the combustion chamber of the engine in order to boost torque and performance.
Intercoolers are used with
Many turbochargers in order to cool the compressed air conveyed by the turbocharger. When the turbocharger compresses air, this will generate heat so the intercooler is essential in cooling this air. Cooler air has more density which means it has more oxygen molecules. And this ensures higher efficiency in the combustion process contributing to higher horsepower. There are different sizes of intercoolers to ensure that they meet the power demands of different applications. Because turbochargers operate at very high speeds, there is a lot of friction and heat generated within the moving parts of the turbocharger. This is where the turbo oil feed line comes in useful as it will supply oil to the turbocharger ensuring proper lubrication. The internal components of the turbocharger are bathed in oil ensuring proper lubrication. And this will reduce heat generation, friction and help in cooling the turbocharger down.
Blow-off valves and diverter valves are also essential for the maintenance of the turbocharger.
The boost pressure generated by the turbocharger will not have a place to go when the throttle is suddenly closed. This occurs during gear changes. But the blow-off valve will release this additional pressure into the atmosphere. If this release doesn’t happen, the compressor wheel can stall and bear damage. The diverter valve can be used to recirculate this additional pressure back into the intake. The boost pressure generated by the turbocharger can be controlled by the wastegate. This is a valve that is used to control the exhaust gas flow driving the movement of the turbocharger turbine wheel. The position of the wastegate can be adjusted in order to control boost pressure and this will prevent over-boosting. You will see external wastegates used in many high performance applications.
You can optimise the air intake with the addition of a high flow air filter.
This will ensure a larger volume of air enters the engine and prevent contaminants from coming in. It will filter contaminants contributing to the health of the vehicle engine. When airflow is increased, combustion efficiency is improved leading to better response. As the function of the turbocharger is intertwined with the exhaust gases produced by the engine, there are performance exhaust systems that can be used to reduce back pressure. This ensures that the exhaust gases go out of the engine in a more efficient way further contributing to the spool-up speed of the turbocharger. The fuel delivery system should match the increased demand created by the increased air intake from the turbochargers and this can be handled by upgrading the fuel pumps and fuel injectors. These will ensure consistent fuel supply to the engine so it will not be starved of fuel even when under-boosting occurs.
