What is the normal turbocharger pressure?

 

For ordinary family cars, it is normal for the pressure of the turbocharger to be between 1.2bar and 1.5bar. Some modified cars will increase the pressure of the turbocharger in order to pursue higher horsepower. The supercharger pressure can even reach 3.5bar, but this pressure value is very dangerous for a family car.

 

Turbocharged engines have superchargers. At the beginning of its birth, turbocharging technology was not applied to automobile engines, but to aircraft engines.

 

Turbocharging technology can solve the problem of insufficient air intake in aircraft engines at high altitudes. Later, turbocharging technology is widely used in gasoline and diesel engines of automobiles.

 

The turbocharger of a turbocharged engine consists of two parts, one is the intake turbine and the other is the exhaust turbine.

 

The intake turbine is connected to the intake manifold, the exhaust turbine is connected to the exhaust manifold, and the impeller of the intake turbine is coaxially connected to the impeller of the exhaust turbine. When the engine reaches a certain speed, the exhaust gas has enough energy to drive the exhaust. The turbine rotates, and the intake turbine also rotates at this time.

 

When the intake turbine rotates, it compresses the air and delivers it to the cylinders, and turbocharging technology can increase the amount of intake air to the engine. If the amount of intake air increases, the amount of fuel injected will also increase accordingly, so that the engine can output more power.
