What's wrong with the slow speed of exploring Yue?
Low-speed reverse gear is caused by the great difference in transmission ratio when the transmission ratio of the upshift gearbox is changed to reverse gear. Yue is equipped with a 2.0T high-power engine and a DBF2.0T low-power engine. Matching the engine is a 7-speed dual-clutch gearbox.
Tan Yue is an SUV model owned by FAW-Volkswagen. Tan Yue is based on the European version of Tiguan and comes from the Volkswagen MQBA2 platform. Externally, Tan Yue adopted Volkswagen's brand-new family-style design language, which is gradually popularized in several new models of Volkswagen. Tan Yue looks younger and more fashionable than Volkswagen's previous family design. The front banner air intake grille, combined with the headlight group with LED light sources on both sides, effectively stretches the lateral visual width. The waistline extends from the front headlights to the rear taillights, and the tail shape is round and atmospheric. The tough lines of the whole car create a sense of muscle.
In terms of configuration, it is equipped with 360 panoramic images, the third generation intelligent parking assistance system, blind spot detection and other conventional functions, as well as TJA traffic congestion assistance system. Through the matching of ACC3.0 adaptive cruise and lane keeping, L2 automatic driving function is realized, which greatly relieves driving fatigue. Equipped with 4MOTION intelligent four-wheel drive system, it can provide four road modes, two off-road modes and one snow mode for optional switching.
What is the hum of Tan Yue's low-speed engine?
The hum of low-speed engines is generally caused by the noise of the electronic fan used to cool the water tank at idle speed, the excessive gap between the piston and the cylinder wall at low speed or speed change, or the sound vibration at high speed.
1. If you don't pay attention to maintenance, it may be that the machine has too much carbon (too much carbon in the engine, too much carbon in the throttle, too much carbon in the spark plug, etc.). ).), can be cleaned in the repair shop.
2. Poor filtration may also lead to (the most common is that the air filter element is too dirty). Just go to the repair shop to clean or replace it.
3. Of course, the purity of the automobile gasoline you use is not enough (because the gasoline purity is not enough, it is easy to form carbon deposits in the machine, and 92 # gasoline is not as pure as 95 # gasoline).
4. This problem will occur if the automobile oil (automobile lubricating oil) is not changed in time or the automobile oil is inferior.
5. If it is the sound made by the transmission shaft, it may be that the ten bytes of the transmission shaft are worn and damaged due to lack of oil. You can remove the drive shaft for inspection.
The engine oil does not fully lubricate all parts of the engine, and the new engine oil can evenly lubricate all parts of the engine after running for a period of time. If it doesn't improve after a period of time, it may be seriously worn, and then cleaning the engine will make the wear gap bigger, the gap bigger, the seal is not good, the condition of the engine will get worse and there may be noise. It is recommended to go to the repair shop for inspection.
The transmission shaft is a rotating body with high speed and few supports, and its dynamic balance is very important. The dynamic balance test of the transmission shaft is generally carried out before leaving the factory, and the adjustment is carried out on the balancing machine. For front-engine and rear-wheel drive cars, the rotation of the transmission is transmitted to the shaft of the main reducer. It can be several parts, and these parts can be connected by universal joints. What's wrong with the low speed in Tan Yue? What happened to the hum of Tan Yue's low-speed engine @20 19?
