Miss Mok, the reader asked: My car has always been opened by me. Later, because the company was close to home, the car was opened by Mr., but recently it was discovered that the engine oil was used much more than when I opened it. May I ask if the burning oil is related to the driving mode? ?

Reply: There is a certain relationship, especially with the T word, once you do not understand the maintenance of the oil-cooled turbocharger (except for water cooling), in the blind driving with the increase of the mileage, to the end will make the turbocharger The wear and tear of the seal ring leads to the burning of oil, and the degree of burning oil is very severe. It is necessary to know that the maximum turbo speed per minute can reach tens of thousands of revolutions or even tens of thousands of revolutions. District was only seven or eight thousand turn).

2. What is the problem of turning off the gear in the downhill?

Mr. Li, the reader, asked: If the car appears to be unstable at idle, what should we do if the downhill neutral block is turned off?

Re: It is possible that the throttle is dirty. It is recommended to go to the 4S shop to clean the idle speed motor and let the staff use the computer to match it. In addition, check the spark plugs by the way.

3. When can't start the engine again?

Miss reader Lu asked: I am a novice. Under what circumstances can the car not start the engine again?

Reply: In the following cases, you can not use the motor or pull the engine to start. You should put the neutral gear or lift the drive wheel and drag it to the professional maintenance factory to inspect and repair:

First, when there is water on the road, the intake and exhaust pipes enter the water, causing the engine to automatically stop and cannot start the engine. Since the cylinder is filled with water, the liquid cannot be compressed. Forcing the starter will cause the connecting rod to bend, break, and cause serious damage to the crankshaft.

Second, the timing belt and belt tensioner should be replaced when driving 70,000 to 100,000 kilometers. If it is found that the timing belt and tensioning wheel and guide wheel are damaged, the engine can not be started at this time, so as to avoid the crank connecting rod mechanism and distribution. The operation of the gas mechanism is not matched, resulting in malign troubles such as top bad valves, pistons, and connecting rods.

3. After the engine is started or running, the oil warning light is on, the oil pressure gauge has no pressure indication, and the coolant warning light is on. Stop the engine immediately and turn off the engine. Do not start the engine until the fault is cleared. Otherwise, the engine will not burn or cause serious cylinder failure.

Fourth, when the engine is running or running, if you hear a serious noise, you should stop and check immediately and you can no longer start driving.

Fifth, the engine fuel system seal leaks. If the nozzle, fuel pipe, or joint leaks, the engine cannot be started before the fault is cleared and the leaked fuel is not cleaned, so as to avoid a fire.

4. What should you watch out for with the steering wheel jitter?

The reader, Miss Pan, asked: Driving in the past few days, I always feel that the steering wheel is shaking. What is this problem?

Reply: There are many reasons: 1. When the car is driving, the steering rod and the tie rod are deformed due to the collision, and the head wears loose or the tire wears irregularly, which makes the toe increase or decrease.

2. When the vehicle is running, due to steering vibration damage, oil leakage or deformation of the front spring will affect the stability.

3. The looseness of the hub bearings and the wear of the left and right steering knuckle ball heads make the front wheels inaccurate.

4. Looseness of the ball or loose support of the transverse thrust rod causes unstable driving.

5. Wheel imbalance, the balance of the original wheel is lost or deformed, resulting in high-speed driving under the state of the car swing, causing the steering wheel to shake.

5. What happened when the transmission sealing port crashed?

The owner of the car asked by Mr. Yang: When I drove, the gearbox seal on the chassis of the car was crashed. Does this affect the performance of the car?

Re: That depends on the extent of the seal's crash. If it is cracked, it may become bigger and bigger. If you can replace it, then change it. If it is a new car, still in the warranty period, you feel serious, it will leak oil, then you will return to the 4S shop for repair.
