Now there are more and more automobile turbo car sales, the main role of this model with T is able to increase the engine intake air, thereby improving the main engine power and torque, so the car is more fresh. But there are automotive professionals said the turbocharged cars in use is luxurious.
Easily damaged by improper use of the engine
Liu three years ago to buy a car with a turbo, the recent discovery engine problems, at every turn on the flame. Mini Cooper turbo Open to the 4S shop to do the inspection, maintenance staff, said, mainly because the owner of the car with a turbo will not be used, which leads to engine failure. Liu said, "I usually just in the town running, little on the high-speed, in addition, is also a parking will turn off, how would such a failure then?"
Turbocharged engine maintenance costs high
Automotive repair professionals chef said that compared with normal naturally aspirated engine, maintenance and repair costs turbocharged engine to be slightly higher, exhaust-driven turbine has a very high speed at work, you need a high quality oil to to achieve lubrication and cooling. After traveling daily parking not immediately turn off the engine and to the engine idle for a while, so get the turbocharger lubrication and cooling, and exhaust emissions, so as to prolong the life of the turbocharger, it will be very easy to damage the engine.
Master Wei said, "If the car usually only in the town, so I do not buy the owner turbo models, because such models at low speeds, 753420-5005S it is difficult to reflect turbo, turbo to be in a lot of By turn three or four thousand cases in order to reflect, but only travel in the town, then on to the number of revolutions has only 2,000 rpm, this turbocharged simply can not play its role. "
It is understood that turbo in repair and maintenance costs are more expensive, in general turbocharged models to be replaced about 60,000 km of new turbines. Further, the turbocharger requires a higher quality oil. This way, the maintenance costs turbocharged car models as well as raising the cost becomes relatively high.
Tips: Use turbocharged engine
Turbocharged engine is started, the accelerator pedal is not urgent, should be idling three minutes, which is to enable the oil temperature rise becomes better flow properties, so that the sufficient lubrication of the turbocharger, and then to increase the engine speed, start driving.
After a long high speed turbo engine, can not turn off immediately. The reason is that when the engine, after a part of the turbocharger oil supply lubrication and for cooling the rotor bearings, the engine suddenly stopped running, the oil pressure rapidly falls to zero, the lubricating oil is interrupted, the interior of the turbocharger heat the oil can not be taken away,C3 GT1544V turbo when the high temperature part of the turbocharger turbine will spread to the middle of the heat bearing housing can not be quickly taken away, while the high-speed rotation of the rotor is still inertia turbocharger. This will result in between the turbocharger shaft and bushing "killed" and damage the bearings and shaft. So turn off the engine should be idling before the three minutes or so, so that the turbocharger rotor speed drops. In addition, it is worth noting that the same turbocharged engine idling unfit for a long time, the general should be kept within 10 minutes.
