Throttle Cleaning of CRDI Engine

I'm sorry for not perfect english. In time I'll do a good quality translate. If you could not get anything please feel free to contact me in comments. I will answer you as soon as possible.

The throttle regulates the flow of air into the engine.

Over time it becomes dirty and poorly can perform its functions. Because it is contaminated crankcase oil with particles passing through it, and also because the exhaust gases. The output of exhaust gases from the EGR valve is located in the intake manifold just behind the throttle.

Symptoms, which can determine the need for cleaning throttle ... I do not know, I can only suggest a partial loss of power at high revs ...

In general, the valve will clean, and for this it needs to be removed. It is situated right in front of the intake manifold during the movement of air.

To remove it, loosen the clamp on the tube, the supply air. Then you can remove the pipe and remove the clamp. And you can move deeper on the hose clamp and tighten it. So it will be more difficult to drop down or even lose.

Remove the air supply pipe and begin to unscrew the screws and nuts (two nuts and two screws). One nut at the bottom, gently unscrew it, carefully pull that fell.

Remove the throttle. We can only tube connected to a vacuum membrane. It is held solely by the force of friction, so that it simply shrinks.

Now the throttle valve can be removed and cleaned. Unlike cleaning nozzles, for this operation does not require any special tools. Only a couple of rags and solvent. If desired, you can even unscrew and remove the inner plate is very good and all washed (still need a screwdriver).
