Why does the car still roll backward when parked on a slope with the handbrake pulled?

How often should a vehicle be inspected after exceeding six years?

Micro and small non-operational passenger vehicles exceeding 6 years require an annual inspection. Within the three-month period encompassing the two months prior to the vehicle's initial registration month, after resolving all traffic violations, bring the vehicle license, compulsory traffic insurance policy, and ID card to the local inspection station for vehicle inspection. Additional Information: 1. For vehicles reaching 6 years, an annual inspection is required. Visit the inspection station to pay fees, undergo exterior inspection, exhaust emission testing, and safety technical inspection. After passing all tests, collect the results, have staff sign and upload them, then receive the annual inspection compliance sticker upon approval. 2. For vehicles within six years, every two years during the three-month period encompassing the two months prior to the initial registration month, after resolving all traffic violations, bring required documents to the nearest traffic police station's inspection window to complete forms and obtain the annual inspection compliance sticker.

Car Air Conditioning: External Circulation or Internal Circulation?

Generally, internal circulation is more commonly used when running the air conditioning in a car. Below are detailed explanations of internal and external circulation in car air conditioning: 1. External Circulation: External circulation refers to drawing air from outside the car, directing it into the air conditioning system for heating or cooling, and then blowing it out through the vents. Essentially, external circulation replenishes fresh air, improving the air quality inside the car. It is used for defrosting in winter or defogging in summer because the air drawn from outside is richer in oxygen and drier, making it more effective for defrosting or defogging. 2. Internal Circulation: Internal circulation draws air from inside the car, creating a cycle of airflow within the vehicle. Its main function is to promptly and effectively block external dust and harmful gases from entering the car. It heats up the car faster in winter and cools it down more quickly when the air conditioning is on in summer. It can also be used during smoggy days. Internal circulation cycles the air inside the car, helping to maintain the interior temperature more effectively.

How to Understand Tire Model Numbers?

Automobile tire model numbers are generally represented by numbers and letters, such as 225/60-R17-99H, where 225 represents the section width, 60 represents the aspect ratio, R represents the tire type code, 17 represents the rim diameter, 99 represents the tire load index, and H represents the tire speed rating. Additional information: 1. Types of tires include: International standard tire codes, which indicate the section width and aspect ratio percentage in millimeters. This is followed by: the tire type code, rim diameter (in inches), load index (permissible load-bearing mass code), and permissible vehicle speed code. For example: In 175/70R1477H, 175 indicates the tire width is 175MM, 70 indicates the tire's aspect ratio is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the speed rating is H. 2. If you encounter tires with the suffix XL, it stands for 'Extra Load' tires. For example, 205/60R16-96H-XL has the same size specifications as the aforementioned tire, but with a load index of 96 (710 kg) and a speed rating of H (210 km/h).

Do Cars Need to Be Charged?

Cars do not need to be charged because they are equipped with a generator. When the engine is running, it drives the generator to produce electricity, which powers all the electrical components in the vehicle and stores excess electricity in the battery. During startup, the car relies on the battery's power to start, and once running, the engine drives the generator. Below are the relevant details: 1. Generator Composition: The generator mainly consists of a stator and a rotor. The rotor's excitation winding rotates within the stator, cutting magnetic lines of force to generate current. This current is then rectified to power the vehicle's electrical components, with excess electricity stored in the battery. 2. Generator Principle: The car's generator produces electricity by continuously running the engine and driving the generator via a belt. Any excess electricity is stored in the battery.

Can China 5 Vehicles Still Be Transferred?

In short, local China 5 vehicles can be transferred normally, while out-of-town China 5 vehicles generally cannot be transferred to the local area. Here is the relevant introduction: 1. Emission standards: As global environmental pollution problems become increasingly severe, countries around the world are introducing stricter emission standards, which greatly benefits the protection of the Earth's environment. The China 5 emission standard was implemented on July 1, 2017, so vehicles that meet the China 4 emission standard were manufactured between 2011 and 2017. Currently, the new China 6 standard has been introduced. 2. Exhaust treatment: Under strict emission standards, automakers actively develop new technologies to reduce engine exhaust emissions.

What Causes the Squeaking Noise from the Car Chassis?

Here are the reasons for the squeaking noise from the car chassis: 1. Corrosion or aging of the stabilizer bar bushings; 2. Damaged brake pads; 3. Malfunction in the connection between the suspension and shock absorbers; 4. Noise from the wheel bearings; 5. Deformation of the shock absorber springs; 6. Aging or wear of the shock absorber pressure bearings. Additional information: The engine chassis primarily serves a load-bearing function, with the car engine and all its components and assemblies mounted on it. The car chassis is composed of the transmission system, running gear, steering system, and braking system, ensuring the normal operation of the vehicle. The thickness of its sealing plastic material can reach 1.5 to 2.5 millimeters, providing protection when the underside is scraped by road protrusions.
