What to Do If There Are Abnormalities in the Driver's License Scoring Date?

What material is the suspension of the Hongqi HS5 made of?

The suspension of the Hongqi HS5 is made of aluminum alloy. The front suspension uses a MacPherson independent suspension, while the rear suspension employs a multi-link independent suspension. Both the MacPherson and multi-link suspensions are commonly encountered independent suspension types. The Hongqi HS5 is a mid-size SUV under the Hongqi brand, with a wheelbase of 2870mm and dimensions of 4760mm in length, 1907mm in width, and 1700mm in height. The Hongqi HS5 is equipped with a 2.0-liter turbocharged engine across all variants, delivering a maximum power of 165kW and a peak torque of 340Nm.

How to Determine if Tires Are Nearing Failure?

Methods to determine if tires are nearing failure include: 1. The tread patterns on the tire surface are almost completely worn out; 2. The tire sidewalls have sustained hard damage due to impacts or other reasons; 3. Sand holes appear on the tire surface, leading to air leakage; 4. Frequent air loss occurs without any identifiable cause; 5. Despite no significant hard damage, the tire has been patched multiple times with excessive trauma. Failing to replace nearly worn-out tires promptly may result in traffic accidents, loss of vehicle control, or breakdowns during driving. Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling.

What are the items included in a major car maintenance service?

Major car maintenance items include changing the engine oil, oil filter, air filter, and fuel filter. Major maintenance is based on the existence of minor maintenance, and these two types of maintenance are usually performed alternately. The oil filter is typically replaced every 8,000 km or once a year. In dry climates, it should be replaced every 5,000 km. The function of the oil filter is to provide clean fuel to the engine, filtering out moisture and impurities from the gasoline, thereby optimizing engine performance and providing the best protection for the engine. A clogged oil filter can obstruct the flow of lubricating oil, leading to poor engine lubrication, increased wear, and even bearing failure.

What Causes Loud Engine Noise During Rapid Acceleration?

The causes of loud engine noise during rapid acceleration are: 1. Exhaust pipe leakage - When there's leakage in the intake or exhaust pipes, the vehicle produces louder roaring sounds as the exhaust flow rate increases during acceleration; 2. Dirty throttle valve - If the throttle valve fails to open to the optimal position due to clogging, it leads to poor air-fuel mixture ratio in the engine, resulting in noise during acceleration; 3. Engine misfire - This mainly refers to situations where one or more cylinders in the engine aren't functioning properly. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors.

What is the typical fuel tank capacity for family cars?

40 to 60 liters. Below are relevant introductions about fuel tanks: General classification: Fuel tanks can be divided into open-type tanks and closed-type tanks. Open-type tanks have their liquid surface connected to the atmosphere, with an air filter installed on the tank cap. Open-type tanks feature simple structure and convenient installation/maintenance, making them widely adopted in hydraulic systems. Closed-type tanks are generally used for pressurized fuel tanks, filled with inert gas at certain pressure (up to 0.05MPa). Classification by shape: They can also be categorized as rectangular tanks and cylindrical tanks. Rectangular tanks are easier to manufacture and more convenient for mounting hydraulic components, hence widely used; Cylindrical tanks offer higher strength, lighter weight, and easier cleaning, but are more difficult to manufacture and occupy larger space - often adopted in large metallurgical equipment.

How Thick Are Car Tires?

Car tires are typically 13 to 15mm thick, with sidewall thickness around 5mm. For off-road vehicle tires, the tread thickness is approximately 20mm, and the sidewall thickness is about 10mm. The specific thickness of a car tire depends on its model. Different vehicle types and tire models have varying sidewall thicknesses and aspect ratios, resulting in different overall thicknesses. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving. They ensure good ride comfort and smooth driving, maintain excellent traction between the wheels and the road, enhance the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car.
