What Causes Steering Wheel Vibration in New Energy Electric Vehicles?

New energy electric vehicle steering wheel vibration is primarily caused by inaccurate four-wheel alignment data and wheel balance issues. Below are detailed explanations: Inaccurate four-wheel alignment data: All four wheels of a vehicle have specific alignment parameters, and they are not simply perpendicular to the ground. It is recommended to perform regular four-wheel alignment checks for your vehicle. If steering wheel vibration occurs when driving between 80 to 90 km/h but disappears when exceeding 90 km/h, this is typically caused by misaligned wheel positioning data. Wheel balance problems: After tires are mounted on rims, some sections of the wheel assembly may be heavier than others, causing vibration during high-speed rotation. It is necessary to check whether the front wheel alignment angles and toe-in meet specifications, and make adjustments if deviations are found. Lift the front axle to rotate the wheels and inspect their static balance condition, as well as check for excessive tire deformation. Deformed tires should be replaced.

What does the annual inspection check?

Inspection items include: body appearance, braking system, steering system, lighting system, tire system, suspension system, and safety equipment checks for each system. Body appearance inspection: Mainly checks for body cracks, deformations, corrosion, intact and complete window glass, complete left/right and rearview mirrors, as well as wipers, engine, radiator, etc. Braking system inspection: Includes brake system self-check, working condition of the air pressure gauge, air compressor belt, and brake line sealing. Safety equipment inspection: Includes emergency door switches, emergency roof hatches, safety hammers, and fire extinguishers.

Is There Any Impact If the Tire Pressure Differs by 0.5 Among the Four Tires?

It will increase fuel consumption and may cause the vehicle to pull to one side, affecting driving safety. Normal range of tire pressure difference: Generally, the tire pressure of a car's four tires cannot always be the same, but the difference between the front and rear tires should not be too large. A difference of around 0.1 bar is considered normal. Impact of excessive tire pressure deviation: If the tire pressure deviation is too large, it will cause different driving resistances among the tires. Especially if the tire pressure on both sides of the same axle is different, it may cause the car to pull to one side while driving, affecting driving safety. Moreover, if the tire pressure difference among the four tires is too large, it will also affect the lifespan of the tires themselves and increase fuel consumption. This is because uneven tire pressure can lead to abnormal tire wear. A tire with excessive pressure will concentrate the vehicle's weight on the center of the tread, causing rapid wear in the center. On the other hand, a tire with insufficient pressure can result in uneven contact area with the ground, increased wear, higher rolling resistance, and ultimately increased fuel consumption.

What is the fuel tank capacity of the Jog 125 scooter in liters?

The Jog 125 scooter has only one model, with a fuel tank capacity of 5.1 liters. Its maximum power is 6.1 kW/rpm, and the maximum torque is 9.7 N·m/rpm at 5000 rpm. The actual displacement is 125 ml. Among vehicles in the same class, the Little Dolphin 110 has a fuel tank capacity of 5 liters. Ways to reduce fuel consumption for motorcycles: Start gently and twist the throttle lightly. For motorcycles with gears, shift gears in a timely manner. Shifting too early or too late is not advisable. Generally, you can listen to the engine sound and must refer to the tachometer—the engine RPM should match the vehicle speed. High throttle or low engine RPM can lead to increased fuel consumption. Always monitor tire pressure, as proper tire pressure can reduce fuel consumption. Both overinflation and underinflation will increase fuel consumption.

What is the situation when the fuel gauge is inaccurate after replacing the fuel pump assembly?

There are three situations, namely the fuel gauge pointer sometimes fast and sometimes slow, the fuel gauge suddenly drops to zero, and the fuel gauge scale rises. Fuel gauge pointer sometimes fast and sometimes slow: This situation is very common, usually manifested as the fuel gauge pointer drops slowly in the first half of the fuel gauge, and after passing the middle scale, the fuel gauge pointer will drop quickly. However, the fuel gauge pointer sometimes fast and sometimes slow cannot be said to be a fault, because it is related to the design of the fuel pump used to reflect the fuel quantity, it cannot uniformly reflect the gasoline consumption, because this uniform change is difficult to achieve, and it is also impossible to change through maintenance or replacement of parts. Fuel gauge suddenly drops to zero: The indication of the fuel gauge depends on the fuel level sensor. When this situation occurs, it means that the fuel level sensor of the vehicle has a problem. It is very likely that the fuel level sensor is contaminated and not cleaned in time. It should be known that gasoline contains many impurities, and the fuel level sensor has been soaked in it for a long time, and it will be polluted over time, directly affecting the accuracy of the indication. Fuel gauge scale rises: This situation is because the connecting rod between the fuel level sensor and the float is stuck, and the float cannot move up and down normally, causing the fuel level sensor not to change, so the fuel gauge pointer is fixed at a certain position.

Do scratches on the rear fender require full panel repainting?

Minor scratches on the fender don't require full repainting, but repair shops usually handle it by repainting the entire panel. Definition of automotive painting: Automotive painting refers to applying a layer of paint to a car's surface to protect it. Baking paint is commonly used for automotive painting. In automobile manufacturing plants, painting is the next process after welding the frame and body. Types include solid paint, metallic paint, and pearl paint. The automotive painting process involves applying putty, sanding, and painting. Precautions for touch-up painting: When repairing a car's paint surface, always go to professional institutions and ensure the work is done by qualified professionals.
