Nowadays a lot of cars on the street running in the rear plus a "T" designation, which is currently more popular turbocharged engine cars. audi a6 1.8 turbo
The biggest advantage of a turbocharger is that it can not increase the engine displacement, based on a substantial increase in engine power and torque. An engine mounted on the turbocharger, and its maximum power output compared to the turbocharger is not installed, can be increased to about 40% or more. In addition, turbocharged engine fuel consumption but also lower than the same power output of naturally aspirated engine, the advantages of these two aspects of the doomed turbocharged engine by more and more people of all ages, audi k04 turbo
but compared to naturally aspirated engines, turbocharged engines appear to be more hypocritical some of the work environment and maintenance requirements to be more stringent, if not properly used and maintained, not only can not play nice turbo effect, but will increase the turbocharger failure rate. Here I will tell you some turbocharged engines require special attention.
Not the car left
After engine start, especially in winter, should be allowed to idle for a period of time in order before the turbocharger rotor speed operation allows the lubricant to fully lubricated bearings. So, do not be started immediately after Meng throttle to prevent damage to the turbocharger oil seal.
Can not turn off immediately
After the high-speed operation of the engine for a long time, should be idle for 3-5 minutes and then turn off. When the engine is working, there is a part of the oil supply turbocharger rotor bearing lubrication and for cooling. After running the engine suddenly stopped, the oil pressure drops rapidly to zero, the high temperature reached turbocharger turbine section of the middle of the heat bearing housing can not be quickly taken away, audi 1.8 turbo
and high-speed rotation inertia turbocharger rotor while still Therefore, the engine heat-up condition if a sudden stop, causing retention turbocharger oil overheating and damage the bearing and the shaft. Particularly to prevent sudden flameout kicks after Meng throttle.
Keep clean
Time to clean the air filter to prevent dust and other impurities from entering the high-speed rotation of the compressor impeller speed instability caused or exacerbated wear bushings and seals. Engine oil and filter must be kept clean to prevent contaminants from entering, otherwise oil lubrication capacity decreased, resulting in premature turbocharger scrapped.
When removing the supercharger, should be kept clean, all fittings must use a clean cloth to plug well, to prevent debris falling into the supercharger, damage to the rotor. Since the supercharger often in high temperature operation, its oil pipeline due to high temperature, internal oil prone coke part, this will result in insufficient lubrication of the turbocharger bearing damage. Therefore, the lubricating oil pipeline after running for some time to be cleaned.
