What Are the Causes of Low Exhaust Turbo Boost Pressure?

[BrookeFitz]

The causes of low exhaust turbo boost pressure are damage to the piping on the exhaust bypass valve or issues with the turbocharger itself, which could be related to oil lubrication problems or excessive temperature. Principle of Turbocharging: A turbocharged engine relies on a turbocharger to increase the engine's air intake. The turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller compresses the fresh air delivered by the air filter pipe and sends it into the cylinders. As the engine speed increases, the exhaust gas flow rate and turbine speed also increase, enhancing the air compression level. This results in a corresponding increase in the engine's air intake, thereby boosting the engine's output power. Function of Turbocharging: The primary function of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful.
