Turbocharged engine maintenance guide must see

First, talk about the construction of the turbocharger

  The turbocharger is actually an air compressor, compressed air, increasing the amount of intake air. It is the use of engine emissions inertia momentum to drive a turbine room turbine, the turbine has led coaxial impeller, saab turbocharger the impeller pressure feed pipe sent by air cleaner air, making it into the cylinder supercharged. When the engine speed increases quickly, the discharge speed of the exhaust gas turbine rotational speed is synchronized with faster, more impeller to compress air into the cylinder, pressure and density of the air increases to burn more fuel and adjusting the amount of fuel corresponding increase in engine speed , it is possible to increase the output power of the engine.

         Exhaust side, the general temperature of the material cast (usually high nickel alloy steel casting)
         Suction side, generally cast aluminum material

         The key components of the turbocharger bearing. This form is named according to the lubrication of the bearing is called "full floating bearings", high working speed, harsh working environment. Therefore, to ensure the lubrication is important. If oil supply due to low oil pressure led to slow, it will damage the bearings causing the turbocharger failure. In a normal engine start is not such a failure, but if the engine oil and oil filter replacement first starts, Subaru turbo it will produce oil supply slow phenomenon, so the lack of oil lubricated bearings. In this case, after starting to about 3 minutes idling operation is not directly improve the speed of the turbocharger to the startup speed. Also, do not make the engine stopped immediately after the high-speed and uphill, to make the engine continues to idle one minute or so, so that continues to idle turbocharger bearings are not short of oil.
         In order to ensure proper cooling of the turbine, often need to stop idling three minutes or more to turn off the engine. A new generation of water-cooled turbocharger, engine parts greatly reducing the cooling time, but from the maintenance of the engine angle, preferably 1-2 minutes, at least idle.
