What is Wastegate?
Wastegate is a piece that has been heard, but not much is known about what it is used for. This piece is something that people are curious about in cases where it malfunctions more. The wastegate is actually the control valve. We can also call this part a valve or valve that helps control the pressure from the turbo. The reason why it is not found in atmospheric engines is also due to the fact that it is a part that controls the pressure of the turbo. This equipment is standard on all turbos, although only on turbocharged engines. The mode of operation, on the other hand, controls the pressure transmitted to the intake manifold, but adjusts the exhaust gas. Because the more exhaust gas increases, the more pressure the turbo will produce.
What Does Wastegate Do?
If a part of the exhaust gas is removed directly from the exhaust with the help of a wastegate, it does not turn the turbine to undergo a turbo. That is why the pressure of fresh air delivered to the intake manifold will also be indirectly much lower. These exhaust gases that come out turn the turbine, and excess exhaust gas is thrown out after it. But here the wastegate is located at the bottom of the turbine, and thanks to this lid, which can be closed and opened, exhaust gases can escape from there when it is opened. This cover can be opened and closed in different ways.
What is the Wastegate mission?
Pinomatically, that is, those who work with air pressure have one diaphragm, and this diaphragm is directly connected to the compressed air produced by the turbo. On the other hand, there is also a spring connected to the exhaust gas and inside this part. When the pressure increases too much, it passes the compression force of the spring and pushes the diaphragm forward. Since this is connected directly to the wastegate on the exhaust side, it opens the cover and the exhaust gases can escape without turning the turbine. The same system can be done electronically. Even in most new vehicles, it is done electronically. There is a sensor in the vehicle, and this sensor is a device for measuring manifold pressure. The data that this sensor reads is sent to the ECU. When it notices that the pressure in the ECU has increased too much, it sends an electronic signal and allows the wastegate to be opened. To help this wastegate open at later pressures in processes such as chip tuning. That is, when you send more pressure to the engine than the factory data, you can get more power. When working in the pinomatic system, a valve could be connected between the old vehicles and the time of closing and opening of the wastegate could be played by increasing or Decelerating the flow of air. The reason for this is that you will send more air, but the fuel map for this must depend on it. After not sending fuel, its excess will only reduce the performance of the engine.
