Compressor Side Of Turbo

Compressor maps are typically shown as contour plots with the islands representative of the compressor stage efficiency.

Compressor side of turbo.

As the hot turbine side is being driven by the exhaust energy the cold intake turbine the other side of the turbo compresses fresh intake air and drives it into the engine s intake. 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. The oil breather vents right there is this a problem. The seals function foremost to prevent pressurized vapor from turbo operation from entering the engine crankcase.

Unfortunately outside debris making its way across the blades of a compressor wheel the intake side accounts for 80 percent of all turbo failures. Stocker has provision for an inlet bell. Oil may be seen inside the turbocharger inside the compressor or turbine on either side of these respective housing seals. The oil breather filter would clear up the oil problem but then there s no positive crankcase ventilation is there.

Or it s just messy and no biggie. This is a commonly confused issue but important to understand. The compressor side of a turbocharger faces significant thermal stress and fatigue challenges. Te44 has the inlet bell integral to the casting.

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. There are critical areas to be aware of on a compressor map. Just a little more lube for the compressor side and vlaves. 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.

Often the problem is not in the turbo itself but rather a peripheral maintenance or turbo installation issue. The two areas that can cause damage to a turbocharger are the surge and choke areas said jim rufini applications engineer for borgwarner. 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. 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.

I noticed the oily film in the turbo inlet while having it apart yesturday. 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.
