Why does my turbo only work sometimes?
The wastegate actuator is not functioning correctly or the boost sensor is not working making the turbo boost properly. Check the wastegate actuator hose and see if its broken and listen for leaks when you drive the vehicle. If the shaft does not turn, then the turbo would need to be replaced.
Why does my car lose speed going uphill?
The most likely issue is a clogged fuel filter. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive. This means you can’t get the power you need if you’re trying to accelerate when overtaking or going uphill.
Where does the boost come from in a turbocharger?
The turbine sits on one end of a spinning shaft. On the other side is the compressor. That is the part that actually makes the boost on the intake side of the engine. The more exhaust gas pushes past the turbine, the more it wants to spin and make boost on the compressor side.
Why does a turbo spin up when the engine is under vacuum?
@generalexception, you just answered your own question: if the engine is under vacuum, it has little load. The throttle must be nearly closed, reducing the total air mass through the system. As the throttle opens, the turbo will spin up as the exhaust energy increases.
Why does my EcoBoost shudder when I go down the Interstate?
Air is drawn through the CAC and moisture collects inside the tubing. Most often this happens when traveling down the interstate when air flow into the motor is relatively slow. Sudden acceleration by the driver, changes the intake air flow rate through the CAC which causes the engine to pull in more air.
How does a turbo work on a diesel engine?
See, on a engine with no load, even without a wastegate the turbo is not doing much. and to make things a bit more complicated here, on a diesel engine it works similar but different. There is no intake air regulation on a diesel, the intake is always unrestricted and output is determined by the amount of fuel injected.
