Speed exceeding 120 km/h steering wheel vibration reasons are as follows: 1. Caused by force feedback generated from tire-ground contact; 2. Various vehicle issues including wheel camber/toe misalignment, tire surface debris, lost wheel weights, deformed rims, excessive steering linkage play, or insufficient tire pressure. Specific tire-related problems include: 1. Uneven tire pressure among four wheels (especially front pair); 2. Uneven tread wear patterns (one-sided wear); 3. Out-of-round wheel rims (steel/aluminum rims deformed into oval shape); 4. Lack of alignment correction after tire replacement; 5. Tire puncture creating a bulge - unnoticeable at low speeds (absorbed by suspension) but generating pronounced frequency vibrations at high speeds.

What Causes Engine Shaking in the Vehicle Body?

The causes of engine shaking in the vehicle body are: 1. Damaged spark plugs, where the wear of the spark plug electrode gap leads to insufficient spark ignition, resulting in incomplete combustion of the air-fuel mixture; 2. Poor quality gasoline, which affects the atomization effect of the fuel injector, causing incomplete combustion of the mixture in the cylinder; 3. Dirty throttle body or excessive carbon deposits on the fuel injector; 4. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor. The function of the engine is to convert thermal energy into mechanical energy by burning and expanding gas in a sealed cylinder, pushing the piston to do work, thereby providing power to the vehicle. The maintenance methods for the engine include: 1. Cleaning the air filter; 2. Removing sludge from the throttle body; 3. Cleaning carbon deposits from the fuel injector.

What license plate does a hybrid vehicle have?

Hybrid vehicles have blue license plates. Hybrid electric vehicles refer to cars that combine fuel and electric power, where an electric motor assists the engine as the main power source. These vehicles are primarily powered by an engine and are equipped with a secondary power source—a battery. Their characteristic feature is that the electric motor assisting the engine can generate strong and smooth power during normal driving, achieving energy savings and emission reductions. License plates refer to vehicle registration plates, which are metal or plastic plates attached to the front and rear of a vehicle. They are made of materials such as aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, or other relevant information.
