What Causes Abnormal Noise When Starting a Car?

1 Answers

The abnormal noise is caused by the meshing of the starter gear and the engine flywheel gear. After prolonged and frequent use, the gears of both the starter and flywheel wear out significantly, resulting in misalignment and grinding sounds. Below are detailed explanations of specific abnormal noises when starting a car: 1. Sharp squeaking noise: This squeaking sound is caused by belt slippage, which may be due to insufficient tension from the tensioner pulley or the belt being stretched over time and becoming loose. For a normal belt and tensioner pulley, when you twist the belt slightly with your hand, it should not rotate more than 90 degrees. If the belt can be twisted over 90 degrees with little force, it indicates that either the belt or the tensioner pulley is loose. 2. Grinding or clicking noise: This sound is caused by the meshing of the starter gear and the engine flywheel gear. The reason is that after prolonged and frequent use, the gears of both the starter and flywheel wear out significantly, resulting in misalignment and grinding sounds.

How to deal with vehicles not driving in the designated lane?

For not driving in the designated lane, traffic police may impose different penalties depending on the specific situation, including fines and deducting 2 to 3 points. Here is the relevant information: 1. Precautions: There are three main types of violations for not driving in the designated lane: first, borrowing the left-turn lane when going straight; second, borrowing the straight lane when making a left turn; third, making a right turn randomly from the left-turn or straight lane. When a motor vehicle passes through an intersection controlled by traffic signals, it should enter the designated lane according to the intended direction of travel at intersections with marked lanes. If a vehicle going straight enters a left-turn or right-turn lane, the electronic surveillance will immediately capture the violation. 2. Penalty: Article 90 states that motor vehicle drivers who violate road traffic safety laws and regulations regarding road traffic rules shall be given a warning or fined between 20 and 200 yuan. If there are other provisions in this law, penalties shall be imposed in accordance with those provisions.

Can You Slam on the Brakes at 120 km/h?

You should not slam on the brakes at 120 km/h, as this can easily cause the wheels to lock up, leading to loss of vehicle control with very serious consequences. The following are the requirements for safe following distance and braking precautions during high-speed driving: Safe following distance requirements during high-speed driving: When driving at speeds above 100 km/h, the safe following distance should be more than 100 meters. When driving at speeds above 60 km/h, the safe following distance should be numerically equal to the speed. On highways, each dashed lane divider line is 6 meters long, with a 9-meter gap between lines.

Braking precautions during high-speed driving: When decelerating during high-speed driving, always press the brake pedal slowly and maintain firm control of the steering wheel throughout the braking process.
