What are the functions of the four major chassis systems?

The functions of the four major chassis systems are: 1. Transmission system: Transmits the engine's power to the driving wheels; 2. Running system: Supports and installs various component assemblies of the vehicle, transmitting and bearing various loads from both the vehicle and the ground to ensure normal vehicle operation; 3. Steering system: Ensures the vehicle can travel in the direction selected by the driver; 4. Braking system: Enables the vehicle to decelerate, stop, and reliably remain stationary. The maintenance methods for the chassis include: 1. Regularly check the assembly oil; 2. Replace brake pads and clutch plates in a timely manner; 3. Perform four-wheel alignment; 4. Monitor tire pressure conditions—excessive pressure can lead to tire blowouts, while insufficient pressure increases vehicle resistance and fuel consumption; 5. Keep the vehicle clean by regularly washing the car and cleaning the chassis; 6. Protect metal parts exposed to the air; 7. Clean the original paint layer; 8. Avoid wetting the car's floor mats to prevent chassis rust.

Why does the car sometimes feel underpowered?

The reasons for a car feeling underpowered are as follows: 1. Insufficient fuel supply: The return oil control valve in the pump cover oil passage is not tightly closed, causing unstable engine operation. In severe cases, the engine may stall under slight load and become difficult to start. 2. Fuel leakage in the fuel line: Air entering the system or a clogged fuel filter can obstruct fuel flow, resulting in weak engine performance. 3. Leakage due to damaged sealing copper gasket of the delivery valve: The delivery valve not closing tightly or a broken delivery valve spring can reduce fuel supply, leading to an underpowered engine. 4. Worn plunger pair causing insufficient fuel supply: This is often accompanied by difficulty starting and unstable operation at low throttle. Additionally, sluggish movement of the plunger or roller body, or weak plunger spring tension, can also affect fuel supply and weaken engine performance. 5. Loose plunger adjusting arm: A broken plunger spring or loose adjusting fork on the fuel supply lever can also impact fuel supply, causing the engine to feel underpowered. 6. Fuel injector leakage or clogged nozzle: Poor atomization quality and incomplete combustion after injection can result in weak engine performance, accompanied by knocking sounds and black smoke from the exhaust pipe.

What does the 'mode' in a car mean?

The MODE button is used to switch between different modes. The MODE button is used to toggle multimedia modes, such as radio or DVD. For example, to switch from the radio to DVD, simply press the mode button. If the MODE button is located on the central control panel, it is used to switch the car's air conditioning airflow mode. Here is some extended information about its functions: 1. Switching multimedia modes: 'Mode' translates to 'mode' or 'direction,' and the mode button is commonly found on multifunction steering wheels and central consoles. If the MODE button is on the multifunction steering wheel, it is primarily used to switch between car multimedia modes, such as FM radio, AM radio, CD, or USB drive modes. 2. Switching air conditioning modes: If the mode button is located in the air conditioning control area of the central console, it is used to switch the car's air conditioning airflow modes, typically cycling between foot-level air, head-level air, and windshield defrost modes. 3. Switching driving modes: The MODE button can also be used to switch driving modes, cycling among three driving modes: normal mode, sport mode, and comfort mode. The sport mode in a car is a driving mode for automatic transmission vehicles, commonly known as the S gear.

Which Types of Vehicles Are Exempt from Highway Tolls?

There are roughly seven types of vehicles exempt from highway tolls. Below is a detailed introduction to these seven types: 1. Public vehicles of the national military and armed police; 2. 'Green channel' trucks that meet relevant regulations; 3. Vehicles approved by the State Council, the Ministry of Transport, or provincial governments for disaster relief; 4. Police cars, ambulances, and fire trucks performing emergency tasks; 5. Work vehicles of local public security, state security, traffic police, and transportation departments; 6. Emergency vehicles for flood control, fire prevention, and disaster prevention in various regions; 7. Small passenger vehicles with fewer than 7 seats during major holidays.

Can You Drive Immediately After Replacing the Windshield?

You can generally drive after replacing the windshield. However, please note the following precautions: 1. Do not wash the car within three days after replacing the windshield, and remove the adhesive tape securing the windshield position only after three days. 2. Try to avoid driving on excessively bumpy roads, and refrain from sudden braking or rapid acceleration to prevent the windshield from shifting. 3. Do not insert parking permits or other cards into the gap between the windshield and the dashboard. 4. Avoid driving on highways and keep the maximum speed below 80 km/h. 5. Do not apply window tint within seven days. Additionally, do not open the windows while driving within three days after replacing the rear windshield to prevent it from shifting due to wind pressure.

Is the Mid-Autumn Festival Highway Free?

Highways are not free during the Mid-Autumn Festival. Below are the specific details about highway toll exemptions: 1. Free holidays: The holidays with toll-free highways are the Spring Festival, Qingming Festival, Labor Day, and National Day. During these toll-free periods, the following vehicles enjoy free passage: passenger vehicles with 7 seats or fewer (including 7-seaters) and motorcycles traveling on ordinary toll roads. 2. Highway toll-free passage method: No card issuance, just lift the barrier for passage. In previous years, the main cause of congestion during toll-free periods was the sudden increase in vehicles on the highways. Although tolls were waived, vehicles still had to stop to receive a card, which involved slowing down before entering the toll station, stopping to take the card, and then accelerating to leave—a process that took about one minute. After the severe congestion during the National Day Golden Week, the Ministry of Transport decided to implement a no-card, barrier-lifting passage method at toll-free lanes, significantly reducing waiting times and improving travel efficiency. The toll-free period is determined by the time the vehicle exits the highway toll lane. For ordinary roads, it is based on the time the vehicle passes through the toll station lane. If you enter the highway during a toll period and exit during a toll-free period, you will not be charged. Conversely, if you enter during a toll-free period and exit during a toll period, you will be charged.
