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.

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. 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. Or it s just messy and no biggie.

The compressor side of a turbocharger faces significant thermal stress and fatigue challenges. This is a commonly confused issue but important to understand. 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. Oil may be seen inside the turbocharger inside the compressor or turbine on either side of these respective housing seals.

This is the compressor side of the 1986 87 stock turbo left and the te44 turbo right notice the the wheel for the te44 is bigger with equal length compressor blades unlike the staggered blades on the stocker. Stocker has provision for an inlet bell. There are critical areas to be aware of on a compressor map. 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.

Unfortunately outside debris making its way across the blades of a compressor wheel the intake side accounts for 80 percent of all turbo failures. 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. The seals function foremost to prevent pressurized vapor from turbo operation from entering the engine crankcase. 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.

Just a little more lube for the compressor side and vlaves. Often the problem is not in the turbo itself but rather a peripheral maintenance or turbo installation issue. 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. The thrust surface for the compressor end is the bearing surface closest to the turbine and vice versa.

Te44 has the inlet bell integral to the casting. I noticed the oily film in the turbo inlet while having it apart yesturday.
