How much longer can a car be driven after exceeding the maintenance mileage?

It can generally run for another 1,000 to 2,000 kilometers. Below is relevant information about car maintenance: 1. Introduction: Vehicle maintenance refers to the collective term for technical tasks such as cleaning, inspection, tightening, lubrication, and adjustment of a vehicle. 2. Expansion: It is usually categorized into daily maintenance, mileage-based maintenance, storage maintenance, seasonal maintenance, initial operation maintenance, and preservation maintenance. Daily maintenance includes pre-trip checks, on-the-road inspections, and post-trip maintenance, primarily aimed at keeping the vehicle clean and ensuring driving safety. Mileage-based maintenance refers to periodic maintenance conducted according to the vehicle's mileage regulations, including non-disassembly primary maintenance and disassembly secondary maintenance. Storage maintenance is the regular upkeep for vehicles that are not in use. Seasonal maintenance is performed before seasonal changes to ensure the vehicle operates normally under different temperature conditions. Initial operation maintenance is the timely maintenance conducted during the initial use of new or overhauled vehicles to facilitate the running-in of various components. Preservation maintenance refers to the maintenance carried out before a vehicle is stored.

Is It Harmful to Idle a Car for Two Hours?

It can have certain impacts on the car. The following are the hazards of prolonged idling: 1. Increased carbon buildup: When the engine idles for a long time, the throttle opening is very small, and the fuel injector sprays highly concentrated fuel to keep the engine running. Therefore, idling itself is more likely to cause carbon buildup compared to driving or highway speeds. Prolonged idling will definitely worsen engine carbon buildup. 2. Fuel consumption: The fuel consumption of a car is quite high when idling. According to tests, idling for three minutes consumes as much fuel as driving one kilometer, meaning two hours of idling can consume almost 2-3 liters of fuel. 3. Shortened engine lifespan: When the engine idles, the temperature and pressure in the cylinders are relatively low, prolonging the preparation time for fuel ignition. Additionally, the sealing of the cylinders decreases, making knocking sounds more likely and shortening the engine's lifespan. 4. Damage to the catalytic converter: Prolonged idling leads to an overly rich air-fuel mixture, resulting in low oxygen content in the exhaust. The unburned mixture can ignite at the catalytic converter, potentially damaging it.

Why Can't the Car Move After Releasing the Handbrake?

If the car still cannot move after releasing the handbrake, it may be due to the handbrake not being fully released or an internal jamming issue. If the car remains immobile even after fully releasing the handbrake, it is advisable to visit a 4S shop to troubleshoot the problem. Below is relevant information about the car handbrake: 1. Introduction to the Handbrake: The parking brake, commonly known as the handbrake, functions to provide resistance when parking, preventing the car from rolling. The parking brake, whether a handbrake or the parking gear in an automatic transmission, locks the drive shaft or rear wheels. The force of the parking brake is much weaker than that of the service brake, sufficient only to prevent the car from rolling on slopes. 2. Precautions for Using the Handbrake: Avoid pulling the handbrake to the highest position frequently, as the handbrake system includes not only steel cables but also nylon ropes. Consistently pulling it to the highest position can quickly cause material fatigue in the nylon ropes.

Why Can the Steering Wheel Turn Three Times?

The reason why the steering wheel can turn three times may be due to issues such as excessive play in the tie rods, ball joints, or the steering gear. It is recommended to promptly visit a 4S shop for inspection and repair. Below is relevant information about the car steering wheel: 1. Definition: The wheel-shaped device used to control the direction of the car, its function is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. 2. Grip: If the steering wheel is viewed as a clock face, the correct hand position is to place the left hand between the 9 and 10 o'clock positions and the right hand between the 3 and 4 o'clock positions. In the event of a collision, this posture is more conducive to supporting the body. 3. Material: The frame is generally made of zinc alloy or aluminum alloy. Some manufacturers are experimenting with cheaper and lighter magnesium alloys, and the frame is produced by die-casting. A small number of manufacturers still use steel sheet metal for the frame, which has a complex structure.

What is Engine Torque Limitation?

Here are the reasons for engine torque limitation in vehicles:1. High and low fuel circuit issues: Blockage in the low-pressure fuel circuit, insufficient fuel intake, or compression of the return fuel line can cause engine torque limitation. Similarly, high-pressure fuel circuit leaks, flow metering unit malfunctions, or high-pressure fuel pump damage can also lead to engine torque limitation.2. Sensor issues: The ECU has an overheating protection function. When the water temperature, oil temperature, or intake air temperature is too high, the protection function will activate, limiting engine power and causing engine torque limitation. Additionally, damage to the water temperature sensor or oil pressure temperature sensor can also result in engine torque limitation.3. Data management problems: Due to existing issues in data management, which may still have some imperfections, there are rare cases where incorrect data may be flashed. This could cause internal control logic errors in the ECU, leading to engine torque limitation.4. Urea nozzle blockage: If the urea nozzle is blocked, it will lose its spray effect. When the ECU computer control system detects such an anomaly, it will limit the engine's torque.5. Use of low-quality diesel: If the engine uses low-quality diesel, excessive sulfur dioxide may enter the catalyst. Once the catalyst fails, the engine's power output will be limited due to excessive exhaust emissions.

What is Engine Oil?

Engine oil, also known as engine lubricating oil. Here is the relevant introduction: 1. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the deficiencies in the performance of the base oil, giving it certain new properties, making it an important component of lubricating oil. 2. Function: The density of engine oil is approximately 0.91kg×10 cubic meters. It can lubricate and reduce wear in the engine, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and act as a shock absorber, earning it the nickname "blood" of the car.
