Here are the reasons for the noise at the back of the car: 1. Insufficient body rigidity: This causes deformation of the vehicle while driving, leading to friction or shaking between the doors and the frame, or friction between steel plates due to welding failure in some areas. 2. Slipping engine belt: Damage to the bearings of the generator, water pump, or power steering pump. 3. Worn bearings: Worn transmission bearings or gears, or bearing spots. 4. Loose components: Faulty shock absorbers or loose suspension components. Below is additional information on the topic: 1. Normal condition: Noise at the back of the car is normal, especially when the trunk or rear part is empty, which can easily cause noise. 2. Examples: Some MPV models, SUV models, and station wagons are prone to noise at the back. If the trunk of these vehicles is empty, the interior panels may resonate and produce noise.

What is the fuel consumption of the Atenza?

The fuel consumption of the Atenza is 6.3L/100km. The actual fuel consumption of a car varies slightly depending on each individual's driving habits and skills. If the driving habits are relatively steady, the fuel consumption will be lower. However, if you frequently engage in aggressive driving, overtaking, or other high-RPM operations, the fuel consumption will increase accordingly. Below are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. If the cooling effect is poor, it will require higher fan speeds and lower temperatures to achieve a comfortable cooling effect. 2. Avoid frequent hard braking: Frequent hard braking is a major reason for high fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid setting the air conditioning too high in small-displacement cars: For vehicles exposed to the sun, do not turn on the air conditioning immediately after getting in. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. After the vehicle has cooled down moderately, then turn on the air conditioning.

How Long Can You Run the Air Conditioning Without Starting the Car?

Automobiles are equipped with interlock mechanisms that automatically cut off most auxiliary circuits after the engine is turned off, including the air conditioning and blower. Below is relevant information about running the air conditioning without starting the car: 1. Battery Function: If the car was just turned off with the air conditioning on, continuing to use the air conditioning merely involves the blower expelling the residual cold air from the condenser. For fuel-powered vehicles, the battery primarily serves to start the engine and balance the vehicle's circuit voltage while driving. The air conditioning compressor consumes a significant amount of energy, and using the car's starter battery to power it will quickly drain the battery and accelerate its failure. 2. Hybrid Vehicles: Hybrid vehicles are similar to electric vehicles in this regard, with the difference being that whether plug-in or non-plug-in, the operation of the hybrid car's engine is sometimes beyond manual control because the engine is also responsible for charging the power battery. In such models, the air conditioning can operate independently of the engine's operation.

What problems will occur if a car continues to drive without engine oil?

Driving a car without engine oil will increase the burden on the engine and cause severe damage to it. When a car runs without engine oil, the engine will lack the necessary protection, including lubrication, cooling, carbon deposit cleaning, anti-corrosion, and anti-wear functions. This will lead to increased friction resistance on the surfaces of engine components, accelerating wear and tear, and causing the gaps between parts to continuously widen. Additionally, without oil to immediately cool and dissipate heat, the engine may suffer from burning or cylinder scoring. These conditions accelerate the aging of engine parts and reduce the engine's service life. When the engine oil is insufficient, the lubrication effect on the friction surfaces of internal components will be poor, leading to inadequate lubrication and increased sliding friction wear on the parts. The oil level should be maintained within the upper range of the oil dipstick. Neither a level below the lower limit nor above the upper limit is acceptable. Excessive oil can increase the engine load, affecting performance. Over time, it may damage the engine's exhaust ventilation system, increase carbon deposits, and even lead to oil burning.

What is the displacement of 330?

Volkswagen 330 torque 1.8T and 2.0T displacement are as follows: The numbers 330, 380, etc. on the rear labels of Volkswagen vehicles represent the engine torque data of the corresponding models. 330 indicates that the engine has a torque between 300 Nm and 350 Nm. It can be the high-power version of a 1.8T engine or the low-power version of a 2.0T engine. The color of the TSI letters on the rear labels of Volkswagen vehicles also provides information: if all three letters are red, it means the vehicle is equipped with a 2.0T engine; if only the letters "SI" are red, it means the vehicle is equipped with a 1.8T engine. Representative models: Tiguan, Magotan. Volkswagen Tharu: Body dimensions: 4506×1809×1685mm, equipped with a 1.8T turbocharged engine, maximum power 118.0kW, maximum horsepower 160PS, maximum torque 250.0Nm. Volkswagen Magotan: Body dimensions: 4865mmx1832mmx1471mm, equipped with a 2.0T turbocharged engine, maximum power 137KW, maximum torque 320Nm.

How much over the speed limit is driving at 100 in a 60 zone?

Driving at 100 in a 60 zone means exceeding the speed limit by 70%. Exceeding the speed limit by 70% will result in a fine, 6 penalty points, and may also lead to the revocation of the driver's license. More relevant information is as follows: 1. Article 42 of the "Road Traffic Safety Law": When driving on the road, motor vehicles shall not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed shall be maintained. When driving at night or on road sections prone to danger, or under weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, the driving speed shall be reduced. 2. Notes: The speed on highways is generally around 100. In a 60 speed limit zone, if a driver exceeds this speed, such reckless driving behavior endangers both their own life and the lives of others. The current road transport environment is very challenging, and the consequences of violations often leave no room for remedy. Under such circumstances, it is imperative that everyone starts with themselves and complies with traffic regulations.
