Turbo wastegate: everything you need to know
Content
Turbowesgate, which translates to deflector valve, is a relief valve for supercharged engines. Its main function is to protect the turbocharger, as well as the engine, from excessive boost pressure.
🚘 What is a turbo wastegate?
Westgate, also called safety valve, часть turbo your car. It is piloted by calculating engine to regulate the pressure received in admission ward... Thus, its role is twofold: it pumps an oxidizer into the engine and relieves excess pressure.
More precisely, it acts as a valve whose purpose is to protect the mechanical elements of the engine by limiting the pressure of the exhaust gases as they pass through the engine's turbine. turbocharger.
Thus, the bypass valve allows the origin of these gases so that they do not pass through the turbocharger, thereby limiting the speed of the compressor impeller. The shape of the wastegate is very similar to the shape of the engine valves. Unlike motors, they are not under the umbrella camshaft but by the strength of the tires.
Today there are two bypass devices:
- Internal wastegate : It is integrated into the turbocharger turbine housing and allows power to be obtained at a very affordable price. It is present in the vast majority of diesel engines;
- External wastegate : it has a mechanism separate from the turbocharger turbine housing. This type of bypass valve achieves more power and is better regulated than an internal bypass valve. However, this requires a different exhaust manifold.
In some cases, an external bypass valve can be installed on a turbocharger that already has an internal bypass valve using a special gasket.
🔧 How do I clean the turbo wastegate?
If your vehicle's turbocharger regularly shuts down and loses power, chances are high that the turbocharger wastegate is faulty. influenza, accumulation of soot happens in small fins and affects how your turbo works.
Required material:
- Protective gloves
- Toolbox
- Detangler
- Turbo seals on inlet and outlet
Step 1. Remove the wastegate.
Remove the two screws that secure the wastegate to the turbocharger and turbocharger control arm.
Step 2. Clean the Variant Part
It must be cleaned with a stainless steel sponge with a penetrating agent. Be careful not to come into contact with the fins of the turbocharger.
Step 3: replace the gaskets
Use new turbocharger inlet and outlet gaskets.
Step 4: reassemble all the elements
Wait a few hours before restarting the engine to allow the turbine to refill with lubricating oil.
👨🔧 How to adjust the turbo boost?
In the presence of turbocharging, regulation is carried out valve by itself deflects gases, alternating the opening and closing phases. Whether you have an internal or external bypass valve, it will self-regulate using its valve and you don't have to adjust it yourself.
💧 How to clean the turbo?
Cleaning the turbocharger of your engine can extend the life of your vehicle and avoid repair costs. In order to clean this room, you will need to bring specific liquids for this. In this way, they will be able to eliminate soot и calamine (in addition to descaling) inside it and clean the assembly without disassembling it.
These additives are poured directly into Fuel tank... This cleaning should be done if you encounter acceleration pits, engine jerks, of turbo whistle or lack of power during the acceleration phases.
💳 What is the cost of replacing the turbo?
The cost of replacing a turbocharger can vary widely depending on the type of wastegate installed on your vehicle. On average, the price of this coin fluctuates within 100 € and 300 €... Consequently, the cost of labor will need to be added to this, the operation may require several hours of work on your vehicle. Think minimum 50 € and maximum 200 €.
Turbocharger wastegate is an integral part of your vehicle's turbocharger function. If he shows signs of weakness, it's time to go see a mechanic. Use our comparison of car services near you to compare rates and change your turbo wastegate at the best price.
