There are two control methods of bypass valve turbochargers, one is mechanical supercharging, which is usually used in truck diesel engines; The other is electronic control, which is usually used in cars.

Exhaust gas turbocharger working principle: exhaust gas from the engine exhaust manifold is high temperature and high pressure, with a certain amount of energy.

Swiss engineer Bich first applied turbocharger to aircraft engine and tank engine, in the existing technical conditions, turbocharger as a mechanical device that can make the engine increase the output power under the same working efficiency.

It is not easy to modify the turbocharger, to improve the power, to rely on fuel combustion in the engine cylinder to do work, so as to output power.

The most obvious effect of turbocharger on the engine is that the turbocharger will increase the mechanical and thermal load of the main parts of the engine, which requires the use of stronger and more high-temperature resistant metals to strengthen the engine.

Properly maintained turbochargers are not easily damaged. The service life of the turbocharger is basically the same as that of the whole vehicle.

When the exhaust turbine pressure is too high, the turbocharger bypass valve will open, so that the exhaust gas from the engine will be directly discharged without passing through the exhaust turbine, so as to avoid the phenomenon of excessive pressure of the turbocharger.

The starting feeling of turbocharged engine is very poor. This kind of slow start is not that the turbocharger works slowly, but that the time required for the turbocharger to reach a stable state will be longer.

Turbochargers have simple structure, do not consume the power of the engine itself, and high boost value. These factors lead to the powerful advantages of turbocharging. But the principle of turbocharging poses one of its biggest pitfalls: high temperatures.

The use of turbocharger accessories in the start of a long time after high speed operation, can not immediately stall. And when removing the supercharger, keep it clean.

The main function turbocharger is to improve the engine air intake, so as to improve the engine power and torque, so that the car more vigorous. This means that the same engine can produce more power when it is supercharged.

In hybrid vehicles, how to adjust the relationship between battery, motor and internal combustion engine has been a concern. According to foreign media reports, Porsche proposed a way to solve the battery cooling problem using turbochargers.
