    cause the galling pattern of wear caused by insufficient lubrication Adhesion wear is a result of micro junctions caused by welding between the opposing rough surfaces rubbing on the counter bodies The load applied to the contacting surfaces is so high that they deform and adhere to each other forming micro joints The motion of the rubbing counter bodies result in rupture of the micro joints where some of the material is transferred by its counter body This effect is called scuffing or galling Eventually this will cause the seizure of one of the bodies by the counter body This is a common sight found when stripping a turbocharger and inspecting the bearing and shaft journals The blue to purple discoloring is caused by excessive heat and the brown colouring on the shaft is the brass adhesion onto the shaft With this in mind it is imperative that the engine builder and or turbo fitter has made sure that the inside of the motor and oil galleries have been cleaned properly and using the correct cleaning material Unfortunately paraffin is one of the worst cleaning materials when used on its own After cleaning it is essential that it gets washed again with HOT WATER and soap at high pressure Oil supply lines need to be replaced as deposits CANNOT be removed by cleaning Most warranty failures are cased by this Posted in failures Turbo Failures Posted on January 12 2013 by nick Reasons for Turbocharger Failure There are three major reasons for turbocharger failure faulty lubrication excessive condensation and a lack of regularly scheduled maintenance Lubrication Failure Proper cooling and lubrication are vital to turbocharger operation Turbochargers are driven by hot exhaust gases exiting the combustion chamber and therefore are subject to extreme temperatures In a Burst Containment Document authored by Honeywell 2 their Garrett Engineering group provides an operating description of its smallest turbo product The article states that the turbocharger s impellers operate up to 200 000 rpm and the exhaust gas temperature can reach a max of 1800 F causing the turbine housing to glow red under certain driving conditions Circulating engine oil through the turbocharger to remove heat and provide lubrication to internal components ensures functional operation A lack of lubrication from degraded engine oil or insufficient delivery from an obstructed oil line can cause increased friction and temperatures In extreme cases of poor lubrication and high operating temperatures moving components can become seized locking up the turbocharger and disabling operation of the vehicle Excessive Condensation Many high performance turbochargers are known for their variable geometry turbines VGT or VNT These units have controlled vanes which help increase or decrease impeller speed within the turbine s housing Seized or sticking vanes cause performance failures on this type of turbo Rust formations on the vanes created by excessive condensation build up when a vehicle is idle for extended periods of time is the cause of failure Condensation can enter the tail pipe or an exhaust manifold gasket

    Compressor Wheel Speed This measurement illustrated as lines across the graph represents the shaft speed of the wheel Remember the faster it spins the hotter the charge air This is why they invented intercoolers The missing pieces of the puzzle here are the engine s redline speed the A R of the turbine side and the volumetric efficiency of the engine How fast an engine runs will impact the shaft speed of the turbo and when optimal efficiency is realized The turbine side of the turbo will determine the spool up characteristics and responsiveness of the unit Turbine performance and engine redline speed are closely related and together both of these factors will have a dramatic effect on the efficiency of the compressor wheel This entry was posted in Turbo Tech and tagged compressor map on May 17 2013 Posted in turbochargers Uncategorized Tagged compressor maps Post navigation CONTACT US Unit 16 6 Pyott street Korsten Port Elizabeth South Africa Tel 041 4510025 Mobile 072 1877214 Int 27 41 4510025 Fax 086 6057963 nick theturboshop co za Please note Google maps shows Pyott street as Pogson street Techno News and Articles 2 stage turbo systems We have moved VNT what
