How to Take Care of Turbocharged Cars?

With high gas prices and environmental protection concerns, the energy saving transform on traditional combustion engines become the mainstream for automobile enterprises. One of the core technology is turbo technology, namely with "T" auto marks. Though the turbocharger cars are more advance than before, their service life is quite dependent on how to do regular maintenance.

Use quality engine oil

As the floating design is mainly used on the turbine rotor, the engine oil fills between the turbine and main turbine rotor, and the whole rotor is cooled and lubricated by the oil. However, inferior quality oil is high in viscosity and poor in liquidity, so it would cause oil seal damages and oil leaking.

Keep turbine clean

Turbine engines has strict requirements on oil cleaning and any impurities can cause turbo parts friction damages. How to keep clean? First, engine oil and filter should be kept clean to prevent impurities, for there is a small gap between a turbine cartridge (central housing rotation assembly) and turbo housing. If oil lubrication works not good, it can cause turbocharger worthlessness soon. Second, air filters need to be cleaned or replaced in time to prevent dirt and other impurities through high speed rotating compressor impeller, as dust particles could broke turbo wheel blade, causing rotation instability, intensified wearing between turbo housing and turbo cartridge CHRA. Finally, quality engine oil, such as synthesis and semi-synthetic types, is advised to use for good turbo maintenance.

Good T-engined auto driving habit

Keep gentle driving when auto engines start. As a turbocharger is cooled by engine and oil lubrication is not good at the start of engine, turbo friction will be intensified with high-speed operation. The oil lubrication will not be good enough for good turbo performance at high speed operation until two or three minutes of turbo running. Pay attention to oil lubrication time, especially in winter.

Avoid immediate car shutdown in high-speed operation. The shutdown may stop oil lubrication very soon and turbocharger internal heat cannot be taken away by oil, so it's easy to cause the turbine cartridge stick to turbo housing. In addition, when an engine suddenly flame out, turbocharger oil will cease to flow. If the turbo exhaust manifold's temperature is very high, the heat can be absorbed into the turbo housing, turning left oil inside turbo into carbon deposit. Therefore, it's necessary to speed down auto engine for 3 minutes or so before flameout in order to slow down turbine rotors. However, turbocharged engines could not run slow for too long long, or the turbo will have bad lubrication due to low oil pressure.
