Compressor Side Of Turbo

In most applications the compressor is ingesting air at slightly more than ambient temperature but the temperature rise across the compressor can be substantial as explained in turbocharger basics at the beginning of this article.

Compressor side of turbo.

Or it s just messy and no biggie. Just a little more lube for the compressor side and vlaves. The seals function foremost to prevent pressurized vapor from turbo operation from entering the engine crankcase. Just make sure to get a beefy set of 90 snap ring pliers i used a nice set of snap on ones and soak it in wd40 for about 1 hour as in let it sit for 1.

By using this otherwise wasted energy to increase the mass of air it becomes easier to ensure that all fuel is burned before being vented at the start of the exhaust stage. Te44 has the inlet bell integral to the casting. On the 10mm bolt holes on the inside of the compressor housing whichever set there are 2 makes it so that the wastegate actuator rod doesnt interfere with the brackets oil lines etc. I noticed the oily film in the turbo inlet while having it apart yesturday.

The thrust surface for the compressor end is the bearing surface closest to the turbine and vice versa. Oil may be seen inside the turbocharger inside the compressor or turbine on either side of these respective housing seals. The oil breather vents right there is this a problem. Since the pressure on each respective side of the turbo acts on the back face of each wheel the pressures tend to pull each wheel away from the other.

Unfortunately outside debris making its way across the blades of a compressor wheel the intake side accounts for 80 percent of all turbo failures. When this failure occurs the leading edge of the compressor wheel s blades will indicate any impact from the object s and the inducer bore what the compressor wheel sits in may show signs of contact or scarring. Compressor maps are typically shown as contour plots with the islands representative of the compressor stage efficiency. The two areas that can cause damage to a turbocharger are the surge and choke areas said jim rufini applications engineer for borgwarner.

There are critical areas to be aware of on a compressor map. Stocker has provision for an inlet bell. The oil breather filter would clear up the oil problem but then there s no positive crankcase ventilation is there. Machined from lightweight non conducive materials such as aluminum the cool side of the turbo called the compressor is where clean ambient air is gathered and forced into combustion.

This is a commonly confused issue but important to understand. Often the problem is not in the turbo itself but rather a peripheral maintenance or turbo installation issue.
