Brake noise can be caused by the following reasons: 1. Metal hard spots on brake pads: If there are tiny metal particles on the brake pads, they will produce a sharp noise when braking. You can try slamming the brakes a few times or grinding and replacing the brake pads. 2. Severe wear on brake discs: After prolonged use, deep grooves will form on the brake discs where the brake pads make contact, causing noise when braking. If the grooves are not deep, they can be resolved by grinding the edges of the brake pads. If the grooves are deep, the brake discs must be replaced. 3. Foreign objects: Foreign objects can cause misalignment of the contact surfaces, leading to noise.

What is the fuel consumption of the Oshan X5?

Oshan X5 has a combined fuel consumption of 6.0-6.3L/100km. There are currently 15 models of Oshan X5 on sale, including the DCT Whirlwind Charge, DCT Hurricane Sonic, DCT Tiger Roar Limited Edition, DCT Elite, DCT Flagship, DCT Luxury, and DCT Premium, with a combined fuel consumption of 6.2L/100km. The manual Elite and manual Luxury models have a combined fuel consumption of 6.0L/100km. The CVT Luxury, CVT Comfort, CVT Premium, CVT Noble, CVT Youth Edition, and CVT Flagship models have a combined fuel consumption of 6.3L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. Actual fuel consumption is higher than this value, ranging from 6.0-8.6L/100km. Specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV weighing about 1.5 tons consumes around 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag, leading to lower fuel consumption. Economical RPM: The engine has a most economical torque output point during operation. Maintaining the car's speed within this torque output range significantly reduces fuel consumption. Typically, small-displacement cars reach this point at about 70 km/h, while larger-displacement cars achieve it at around 100 km/h. Staying within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at traffic lights can increase fuel consumption.

What is the difference between Nissan GTT and GTR?

Here are the differences between Nissan GTT and GTR: Different purposes: The GTT is a great drift car, while the GT-R requires the removal of its four-wheel drive system to perform drifts. The GT-R is a high-performance, high-reliability, high-power sports car produced by Nissan, belonging to the Skyline series under Nissan. Appearance: The GT-T has good body rigidity. For the GTT, except for the taillight assemblies and side skirts, many parts are interchangeable between the two-door and four-door models. The GT-R, on the other hand, embodies the essence of design, incorporating futuristic and avant-garde elements to create a unique new image. It has also become a classic in terms of aesthetics, breaking away from the traditional sedan image.

What is the reason for the missing mileage display on the 10th generation Accord?

10th generation Accord missing mileage display may be caused by instrument panel malfunction or manual reset of the odometer. Below is relevant information about vehicle mileage: Introduction: The car odometer displays vehicle speed in km/h (kilometers per hour). It consists of two gauges - a speedometer and an odometer. Typically located directly in front of the driver's position, identification methods include judging by wear degree or checking the vehicle's maintenance records at a 4S shop. Principle: Traditional speedometers are mechanical, typically connecting to a flexible shaft containing a steel cable. The other end of the shaft connects to a gear in the transmission. The rotating gear drives the cable, which in turn rotates a magnet inside the odometer housing. The housing connects to the needle and positions it at zero via a hairspring. Variations in the magnet's rotation speed alter magnetic flux, disrupting balance and causing needle movement.

What are the reasons for the BYD Qin DMi-EV being restricted?

BYD Qin DMi-EV being restricted may be caused by battery pack failure, BMS failure, drive motor controller failure, or related circuit failure. When the vehicle has an EV function restriction, it should be immediately taken to a repair shop or 4S store for professional repair to avoid unnecessary trouble during use. Below is related information: Advantages of pure electric vehicles: The biggest advantage is that they are very environmentally friendly, generally producing no tailpipe emissions, so they do not cause pollution to the environment. Moreover, pure electric vehicles produce very little noise during driving, making the ride quite comfortable. Disadvantages of pure electric vehicles: However, the disadvantages of pure electric vehicles are also quite clear, namely that their range is certainly not as good as that of fuel-powered vehicles. If in remote areas, charging may not be very convenient. Furthermore, in terms of nationwide coverage, pure electric vehicles still have a long way to go.
