What causes abnormal noise from the rear wheel of an electric car?

Causes of abnormal noise from the rear wheel while driving: Car tire issues: Foreign objects stuck on the tire surface can cause a flapping sound while driving; small stones lodged in the tire grooves need to be removed promptly, or if the tire is punctured, uneven tire pressure among the four wheels can lead to abnormal noise; deformed or bulging tire treads, severe wear can produce a low thumping sound during driving. Brake pad and bearing issues: Excessively thin brake pads will produce a metal scraping sound when worn too thin; insufficient lubrication or excessive wear of bearings can cause wheel bearing noise.

Should the turn signal be kept on when pulling over?

When pulling over, the turn signal must be kept on to alert other traffic participants in advance that the vehicle is entering a parking state. Here are specific details about turn signals: 1. Introduction: The turn signal is an important indicator light that is activated when a vehicle turns to alert vehicles and pedestrians in front, behind, and on both sides. The turn signal uses a xenon lamp tube and is controlled by a single-chip microcomputer circuit, working continuously with alternating left and right flashes. 2. Function: The main purpose of the turn signal is to inform surrounding vehicles that you are about to change direction, prompting them to yield to avoid collisions. Therefore, whether turning, changing lanes, overtaking, starting, or parking, as long as your vehicle needs to steer away from the original lane, the turn signal should be activated in advance. This is a fundamental principle of safe driving.

Why does the car accelerate slowly with high RPM but the speed doesn't increase?

The car accelerates slowly with high RPM but the speed doesn't increase, which may be due to insufficient gasoline, insufficient cylinder pressure, ignition system failure, etc. Here is some extended information about gasoline: 1. Development background: In the mid-19th century, people did not yet recognize the importance of gasoline, and kerosene for lamps was widely used at that time. The petroleum refining process relied on simple distillation to separate the components of petroleum with different boiling points. Kerosene components had a higher boiling point and were safer to use in lamps, making them the main product of crude oil refining, while gasoline and other components were often burned as fuel. 2. Carcinogenic substances: On October 27, 2017, the International Agency for Research on Cancer (IARC) of the World Health Organization published a preliminary reference list of carcinogens, in which engine exhaust and gasoline were listed in the 2B category of carcinogens.

What are the penalty items for the slope parking test in Subject 2?

Penalty items for slope parking are as follows: After parking, if the right side of the vehicle body is more than 30 cm from the roadside line, 10 points will be deducted; if it exceeds 50 cm, 100 points will be deducted; crossing or touching the line results in a 100-point deduction. After parking, if the front bumper is not aligned with the pole line and the deviation does not exceed 50 cm, 10 points will be deducted; if it exceeds 50 cm, 100 points will be deducted. After parking, failing to fully engage the parking brake results in a 10-point deduction. Failing to start within 30 seconds results in a 100-point deduction. Stalling the engine once during startup results in a 10-point deduction. Starting the engine without the gear in neutral or park results in a 100-point deduction. If the vehicle rolls back less than 30 cm during startup, 10 points will be deducted; if it rolls back more than 30 cm, 100 points will be deducted. Key points for slope parking operation: Upon hearing the "slope parking" instruction (approximately 20 meters from the pole), turn on the right turn signal, steer appropriately to the right, and drive slowly along the right side of the road, paying attention to the distance between the vehicle body and the right roadside line. When the vehicle is about 10 meters from the parking pole, approach the target slowly, accurately, and steadily. Aim accurately at the target, using a specific point on the parking pole and the windshield (or hood) as a reference (this point should be determined during practice, as it varies by vehicle type and driver height). When the reference point on the windshield aligns with the parking pole, meaning the vehicle bumper aligns with the parking pole line, stop immediately.
