Compressor Side Of Turbo

This is a commonly confused issue but important to understand.

Compressor side of turbo.

The oil breather filter would clear up the oil problem but then there s no positive crankcase ventilation is there. 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 compressor side of a turbocharger faces significant thermal stress and fatigue challenges. Te44 has the inlet bell integral to the casting.

There are critical areas to be aware of on a compressor map. 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. 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.

Oil may be seen inside the turbocharger inside the compressor or turbine on either side of these respective housing seals. Compressor maps are typically shown as contour plots with the islands representative of the compressor stage efficiency. 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. I noticed the oily film in the turbo inlet while having it apart yesturday.

Unfortunately outside debris making its way across the blades of a compressor wheel the intake side accounts for 80 percent of all turbo failures. 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. Stocker has provision for an inlet bell.

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. Or it s just messy and no biggie. 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. The two areas that can cause damage to a turbocharger are the surge and choke areas said jim rufini applications engineer for borgwarner.

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. The thrust surface for the compressor end is the bearing surface closest to the turbine and vice versa.
