Oil Catch Can - erfaringer??

[dannemare 21]

Overvejer at få en catch can (olieopsamlingsbeholder?) monteret på min næste (turboladet) bil. Nogen der har erfaringer med dem? Er der eksempelvis faldgruber, man skal være opmærksom på? Hvor ofte plejer folk at tømme dem (ved normal pendling, ved banekørsel)? OIL CATCH CAN Blow-by is a constant problem with any turbocharged engine. While a normal byproduct of the combustion process if it isn’t contained outside the engine it will collect and gum up the valve train, turbo and most importantly the intercooler and plumbing. When this occurs it reduces the thermal efficiency of the intercooler, thus losing power and performance. http://www.perrinperformance.com/products/show/56 PCV tube stands for the Positive Crankcase Ventilation tube (PCV). It's used to vent any pressure built up in the head of the engine, but since we have emissions laws, that venting means that the gasses must be properly burned to prevent excess pollution. This is done by sending the gasses back into the engine through the intake. When this occurs not only will the engine have a pushing pressure, the intake will also have a sucking action working on the tube. This results in a force so great that gasses AND oil will be transferred from the engine and into the intake manifold. In other words, it results in burning oil. What's bad about burning a little oil? As oil gets sucked in, the throttle body, intake manifold, cold start fuel injector, and T-VIS butterflies develop a thick oily residue which coats everything it touches. When the tiny particles of dust and dirt that make it past the air filter come in contact with that oil, they bond together making a thick sludge. In the most severe cases, this can lead to the complete failure of the T-VIS system when the butterflies get so gunked up they can no longer open and close properly. The bad part about getting the throttle body dirty in particular is that it has sensors within it that contribute to the info the ECU needs to properly run the engine. Those sensors can't operate properly if they're covered in an oily residue. I'm not certain how bad it is for the cold start fuel injector, but I'm fairly certain the injector wasn't designed to operate while covered in crap. The solution is to clean the throttle body, injectors, and intake manifold periodically to insure that the oil residue is removed, or you can remove the oil BEFORE it enters into the throttle body/intake manifold. This can be done using a PCV catch can. http://www.gassavers.org/showthread.php?t=290 QVRad3aPdVA
