Most of the adjustment devices of the current turbocharger accessories are adjusted on the exhaust side. When there is no need for supercharging, such as idling or when there is a sign of deflagration, part of the exhaust gas will leak out through the bypass valve and not enter the turbocharger. When the engine speed reaches 1800 revolutions per minute, the solenoid valve closes the bypass valve to direct the exhaust flow to the side of the turbine, so that the turbine turns. In addition, there is another design, which is to adjust the angle of the turbine blades, and adjust the speed of the turbine through the change of resistance, thereby changing the boost amount.

Cooling the air can shrink the air to increase its density, pack more air into the same volume, and prevent deflagration. Therefore, the turbocharger of a car is equipped with an intercooler. This intercooler is generally air-cooled and installed in front of, next to the engine radiator, or in a single position, and is cooled by the car's head-on airflow or its own fan. the

A key part of a turbocharger is the bearing. This kind of bearing named according to the lubrication form is called "full floating bearing", which has extremely high working speed and harsh working environment. Therefore, it is very important to ensure lubrication. If the oil supply is slow due to low oil pressure, it can damage the bearings and cause the turbocharger to fail. This kind of failure will not occur during normal engine start, but if the engine is started for the first time after changing the oil and oil filter, the oil supply will be slow and the bearing will lack oil lubrication. In this case, it should be idled for about 3 minutes after starting, and the speed cannot be directly increased to the starting speed of the turbocharger. Similarly, do not stop the engine immediately after high speed and uphill, but keep the engine idling for about 1 minute, so that the turbocharger bearings that continue to idle will not be short of oil. Therefore, drivers who use turbocharged cars must follow the manufacturer's instructions and pay great attention to the quality of the engine oil. It is not advisable to treat turbocharged cars as ordinary cars.
