Turbocharger Maintenance is best to choose synthetic lubricants

Release date:2015-12-24 00:00 source:http://www.sdtturbo.com Click:

 Since the Volkswagen pushed TSI technology ( direct injection turbocharging into the engine cylinder ) at first in Chinese market, now more and more manufacturers produced the turbocharger cars, such as new Regal, the new Lacrosse, Hideo is the car manufacturer which used turbocharger technology. Compared to the naturally air intake engine, engine with turbocharger has more power output. but the maximum explosion pressure the average temperature increases significantly under turbocharger engine working. Therefore, there is a higher requirements on maintenance and repairing. Then how to maintain and use the turbocharger engine?

NO. 1

Choose the high quality lubrication oil

At present, the life of turbocharger engine has been greatly improved, it can achieve all life as same as the vehicle life, they never damage which run 100000 kilometers, even 200000 kilometers. At present most of the damaged turbochargers is due to sealing damage between turbocharger and air inlet pipe , it causes the burning of lubricating oil. The main reason of the oil sealing damage is replacement cycle of the lubricating is too long or to use inferior lubricating oil .This may cause lack of lubrication and cooling of the main shaft with journal bearing ,then damages the oil sealing to lead to oil leakage.

in addition, the turbocharger starts working when the engine at the speed of 3500 RPM/min , and increases rapidly until 6000 RPM/min. And the higher the engine speed requests the anti-shear ability of lubricating oil to be higher. Only in this way, it can make the ability of   lubrication be stable under working at high speed.

Therefore when choose lubricating oil,we should choose high quality lubricating oil, such as high-grade fully synthetic lubricating oil and so on.       

NO.2

Keep the turbocharger clean

Great power from turbocharger engine depends on its sophisticated design and processing, meanwhile this also requires its harsh working environment. As a result,the clean protective requirements for lubricating oil is very high, any impurities will cause damage for the parts, especially it need to keep turbocharger cleaning .

First of all, the lubricating oil and oil filter should keep cleaning to avoid entering impurities. Because the space is very small between turbocharger shaft and journal,  oil lubricate ability decreases ,it will cause turbocharger “dead”. So it should clean and replace air filter timely to avoid impurities entering to turbocharger blade with high speed.

In addition, the owner should check the if the turbocharger has unusual sound or shocking regularly and if sealing ring seals . Because turbocharger maintenance technology is higher than common naturally air intake engine technology , so, it is best to go to professional 4 s shop for maintenance.

It doesn’t need to idle and cool down when switches off the engine

As the turbocharger temperature is high when it drives at high speed, therefore, before the cars which equipped with turbocharger can not stop immediately after driving, it need to idle a few minutes, let some of the lubricating oil offer lubrication and cooling for the turbocharger.

But service experts from Volkswagen introduces that, the Volkswagen cars with the turbocharger have solved question of the cooling. Owners can switch off the engine directly when they get into the service area. 

Technical staff introduces, the owner should try to drive softly. Because turbocharger relies on lubricating oil to cool down ,the lubrication is not good when we star the car in a moment,if the turbocharger works at high-speed at this moment, the wear and tear will be very serious.
