Car tires and spare tires are not all the same. Generally, a car is equipped with a spare tire, which can be either a full-size spare or a non-full-size spare. A full-size spare tire has the same specifications as the original car tires, while a non-full-size spare has different specifications to remind the owner to check and replace it promptly. Types of spare tires include: 1. Full-size spare tire: The specifications of a full-size spare are exactly the same as the other four tires on the car, allowing it to replace any temporarily or permanently unusable tire; 2. Non-full-size spare tire: This type of spare has a slightly smaller diameter and width compared to the other four tires, so it can only be used as a temporary replacement and is limited to non-driving wheels; 3. Run-flat tire: Also known as a safety tire, commonly referred to as a 'run-flat' or 'anti-burst' tire.

To be honest, the regular tires on a car and the spare tire are completely different things. The regular tires are mounted on the car for daily driving—they're durable, wear-resistant, and suitable for all kinds of road conditions. They're what keep my ride stable. As for the spare tire, it's just an emergency tool, tucked away in the trunk. It's smaller in size, lighter in weight, and designed as a temporary solution for flats or leaks. Don't expect to use it for long-distance driving—speeds over 80 km/h could lead to loss of control, and the tire wears out quickly. The spare's material is inferior, with a limited lifespan, and if left unused for too long, it can age and leak. So, if you ever have to use the spare, drive straight to a repair shop to get the regular tire replaced. Don't cut corners by treating the spare as a main tire—safety first.

What is the working principle of the engine starting system?

The working principle of the engine starting system is: the battery provides electrical energy, under the control of the ignition switch and the starter relay, the starter converts electrical energy into mechanical energy, drives the engine flywheel ring gear and crankshaft to rotate, and the starting work can cycle, so that the engine enters the self-running state. The working process of the car starting system: 1. Turn the ignition switch to the ON position with the key, the instrument is powered on, and after a few seconds, the car enters the ready-to-start state; 2. Turn the ignition switch to the START position to connect the circuit of the battery and the starting system; 3. The starter relay is energized; 4. After the starter is energized, the main shaft rotates under electromagnetic action; 5. The drive gear on the main shaft of the starter rotates, driving the engine flywheel and crankshaft to rotate; 6. Under normal circumstances, after a brief start, the engine can enter the automatic running state.

Which lights should be turned on for vehicles at night?

When driving at night, you should turn on the low beam headlights, and always use the turn signals when making a turn. Here is a partial introduction about the use of lights: 1. Urban roads are well-equipped with lighting facilities, so there is no need to turn on the high beam headlights. However, if you encounter a situation where there is insufficient lighting ahead, you should turn on the high beam headlights because they are positioned higher than the low beam headlights, allowing them to illuminate objects that are far and high. 2. Low beam headlights are designed for close-range illumination. Their design requires a wide illumination range but a short illumination distance, and the focus cannot be adjusted. 3. City roads have heavy traffic. Using high beam headlights not only causes glare for oncoming vehicles but also affects the visibility of pedestrians on both sides of the road.

Is the Recirculation Light On or Off?

The air conditioning system's recirculation and fresh air buttons generally come in two types. The first type has separate buttons for recirculation and fresh air modes, where an illuminated light indicates the active function mode. The second type combines both functions into a single button, where an illuminated indicator signifies recirculation mode, while an unlit indicator means fresh air mode. More details are as follows: 1. The purpose of the air conditioning recirculation mode is to prevent outside air from entering the vehicle. When outside temperatures are extremely high or low, using recirculation mode allows the air conditioning system to operate in this mode briefly, quickly lowering or raising the interior temperature. 2. The fresh air mode allows outside air to enter the vehicle for circulation. If equipped with an air quality sensor, the system will automatically switch to recirculation mode when detecting increased concentrations of harmful substances in the outside air, preventing it from being drawn into the cabin. 3. Once the concentration of harmful substances in the outside air drops to normal levels, the system will automatically deactivate recirculation mode, allowing fresh air to enter the vehicle again.

What Causes Engine Shaking and Stalling During Cold Start?

There are two main reasons for engine shaking and stalling during cold start. Below are the relevant explanations: 1. Dirty throttle body: This can cause the throttle valve to not close properly or the idle speed control motor to get stuck, both of which can lead to excessively high engine idle speed. Therefore, when the vehicle experiences shaking, the first step is to inspect the throttle body and fuel injectors. If excessive dirt is found on the throttle body or excessive carbon buildup on the fuel injectors, they should be cleaned promptly. 2. Worn engine mounts: Engine mounts serve as the vibration damping system for the engine. If there are issues with the engine mounts, it can cause shaking during idle. The engine load increases when electrical systems are turned on, leading to a drop in idle speed. To compensate for the shaking caused by this drop, the engine automatically raises the RPM slightly. When turning on the vehicle's electrical systems, especially when starting the car air conditioning in summer, the engine often exhibits shaking.

What does the yellow exclamation mark on the Volkswagen dashboard mean?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Faults: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. There is also a red exclamation mark inside a circled bracket, which represents a brake system warning, mainly indicating brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents.

What are the reasons for the fuel injector not spraying fuel?

There are several reasons why a fuel injector may not spray fuel: 1. Insufficient fuel: Generally, when the fuel warning light comes on, a car can still travel about 40-50 kilometers. Therefore, many car owners may not refuel immediately when the warning light appears. However, if not handled properly, this can lead to a severe shortage of fuel in the tank, causing the fuel injector to stop spraying fuel. 2. Fuel pump damage: The fuel pump relies on fuel for cooling and lubrication. If the fuel level in the tank becomes critically low, the fuel pump is highly susceptible to damage. 3. High-pressure fuel pump failure: To increase the fuel injection pressure and improve fuel atomization, fuel is pressurized a second time by the high-pressure fuel pump before being sprayed by the injector. If the high-pressure fuel pump fails, causing a sudden drop in fuel supply pressure, the fuel injector's operation will be affected. 4. Fuel injector clogging: Unsaturated olefins and gums in fuel can form a coking-like substance under high temperatures, commonly known as carbon deposits. If carbon deposits accumulate severely on the fuel injector, it is highly likely to become clogged, thereby affecting its ability to spray fuel.
