Since the turbocharger is driven by the engine exhaust

      Light traffic computer will be reduced by increasing the amount of fuel injection cylinder temperature, but significantly improve the fuel consumption of the consequences of lack of motivation; serious especially when public tsi, Audi tfsi such direct injection turbocharged engine, in order to improve fuel economy supply system of "lean burn" state work, Citroen 1.6 turbo the internal temperature is higher than the traditional cylinder turbocharged engine. Top of the piston under conditions of severe knock trip computer provides extra fuel will cool quickly, so that the piston top "annealing" final breakdown, the Chinese market, sales of Audi cars tfsi there have been many instances. So turbocharged engine or the use of 97 or more high-grade gasoline relatively safe.
         Since the turbocharger is driven by the engine exhaust, the supercharger blades in the side of 500-750 degrees Celsius under high temperature environment to work in pressurized speed up to 15-20 million revolutions per minute. The turbocharger and no separate lubrication system, the engine oil needs additional supercharger lubrication, it is necessary to use a higher viscosity oil temperature is more, relatively stable performance synthetic oil helps to ensure that the turbine the life of the turbocharger.
         In particular, after a long cool place to start the car, and there is no adequate internal turbocharger oil, the need to maintain at least a half a minute to start the vehicle idling. After the high-speed driving for a long time, the axis of the turbocharger is in the hot state, if the axis of the oil around the flameout stop cycles, it is prone to carbonization. After the formation of oil sludge carbonization may eventually make the axis stuck or broken, even with a water-cooled turbocharger features also need to keep idle 1-2 minutes to flameout.
         In addition to the above points, turbocharged engine also need to pay attention to maintaining clean air filter, if inhaled dust or foreign matter turbocharger blades will damage or even fall off, so the need for timely replacement of the air filter and check the air filter box seal. Turbocharged engine cooling system requirements are more stringent, Mini 1.6 turbo in addition to regularly check the coolant inventory, but also to keep the tank clean the heatsink. Further, in the cold air for cooling the turbocharger also requires frequent cleaning fins.
         By several measures above, turbocharged engine can reach a normal life and has provided a strong impetus. But now the life of the turbocharger is still 150,000 km up and down, Mazda 1.6 turbo in terms of post-maintenance or overhead is relatively large.
