At 20,000 kilometers, a car requires an oil change, replacement of the oil filter, air filter, and spark plugs. Below are the detailed explanations: 1. Oil and oil filter replacement: Under the high-temperature and high-pressure conditions inside the engine, the oil's shelf life is significantly shortened, and its performance deteriorates. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing with the oil, which can cause oxidation and the formation of sludge that clogs the oil passages. Both the oil and oil filter should be replaced simultaneously. 2. Air filter: If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer mark. The air filter blocks dust and particles that the engine might suck in during the intake process. If the filter isn't cleaned regularly, dust can enter the engine, leading to abnormal wear on the cylinder walls. 3. Spark plugs: If the car uses standard spark plugs, preparations should be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel efficiency. If you notice a lack of engine power while driving, it's time for maintenance. The lifespan of spark plugs varies depending on their material.

What Causes Difficulty Starting a Cold Car but Normal Operation When Warm?

Here are the reasons why a car may have difficulty starting when cold but operates normally when warm: 1. Reason one: Poor fuel quality. Low-quality fuel often has poor volatility, especially in winter when temperatures are low. During a cold start, the engine block temperature is low, making it difficult for the fuel to atomize. This results in fuel injected into the cylinder not mixing sufficiently with air, leading to difficulty starting or even failure to start. 2. Reason two: Excessive carbon buildup on the valves and intake manifold causes difficulty starting when cold. Since carbon deposits can absorb a certain amount of fuel, the ECU makes incorrect judgments. For example, the computer may control the injection of 100 units of fuel-air mixture, but only 90 units actually enter the cylinder (10 units are absorbed by carbon deposits). 3. Reason three: The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits further affects whether the cold start proceeds smoothly. Carbon deposits in any part of the engine can negatively impact its normal operation.

What Causes Weak Acceleration in Manual Transmission First and Second Gears?

The primary reason is unskilled gear shifting operation, failing to shift gears in time after reaching the corresponding RPM. Below are specific tips for manual transmission gear shifting: 1. Downshift after deceleration: Increase speed before upshifting, and reduce speed by releasing the throttle before downshifting. Always fully depress the clutch pedal before shifting, and operate the gear lever with light, quick, gentle, and precise movements. 2. Master the timing of gear shifts: Shift when the engine RPM is around 2000. First press the accelerator, then the clutch to prevent forced disengagement before shifting. Downshift based on vehicle speed; generally, downshift when engine RPM drops below approximately 1500. 3. Ensure smooth shifting actions: Fully depress the clutch in one motion and engage the gear in one smooth movement. Familiarize yourself with the gear positions. If unable to engage a gear, shift to neutral, release the clutch briefly, then depress it again to successfully engage the gear.

Will points be deducted if caught smoking while driving by an electronic eye?

Smoking while driving and being captured by an electronic eye will result in point deductions. Here are some daily driving precautions: 1. Develop the habit of fastening your seatbelt when getting in the car: The importance of seatbelts for driving safety is self-evident, and many bloody examples have warned that you must fasten your seatbelt when entering the vehicle. However, there are always some people who feel that seatbelts restrict their movement space or even find them uncomfortable and choose not to wear them. 2. Ensure the car door is properly closed while driving: Sometimes, the car door may not be tightly closed; in the event of an accident, a loosely closed door could lead to fatal consequences. If you are unsure whether the door is securely closed, do not hesitate to open it and close it firmly again. For vehicles equipped with a door-ajar warning function, pay attention to whether there is an alarm sound or if a warning light is illuminated on the dashboard.

Will Starting the Car with Clutch and Brake Pedals Pressed Damage a Manual Transmission Vehicle?

No, it will not cause damage. On the contrary, this is the correct operating method that can effectively protect the vehicle. Below are specific details about manual transmission vehicles: 1. Definition: A manual transmission vehicle is one that uses a manually operated gear-shifting mechanical transmission to regulate speed. This means the driver must manually move the gear lever to change the gear engagement positions inside the transmission, altering the gear ratio to achieve speed changes. 2. Advantages and Disadvantages: The advantages of manual transmissions include simple structure, reliable performance, low manufacturing and maintenance costs, high transmission efficiency, and theoretically better fuel economy. Additionally, due to pure mechanical control, gear shifts are more responsive and can more directly reflect the driver's intentions, providing a more engaging driving experience. The disadvantages include more complicated operations and noticeable jerking during gear shifts. 3. Working Principle: In manual transmission vehicles, the power input shaft is connected to the clutch. The power transmitted from the clutch is directly passed through the input shaft to the gear set, enabling gear shifting.

Does mismatched speed and gear in Subject 3 result in point deduction or failure?

Mismatched speed and gear in Subject 3 will result in point deduction. The reason for speed-gear mismatch is that the clutch pedal isn't fully depressed during gear shifting. When shifting to a higher gear, the increased speed isn't detected by the system as a gear change signal, causing it to assume the vehicle remains in the lower gear, which naturally leads to point deduction due to speed mismatch. The key challenges in Subject 3 examination are as follows: 1. Speed-gear mismatch: Errors involving high gear at low speed or low gear at high speed must be avoided during the test. Before shifting gears, ensure the speed is adjusted to match the target gear. 2. Deviation in straight-line driving: Many candidates deliberately reduce speed due to concerns about maintaining a straight path, which is inadvisable. This actually increases the likelihood of trajectory deviation, so maintaining appropriate constant speed is crucial. 3. Parking over 30cm from curb: Subject 3 explicitly requires parking within 30cm of the curb, but this distance proves difficult for many candidates who often park too far from the roadside.

What are the reasons for the squeaking noise in Volkswagen Polo's brakes?

There are several reasons for the squeaking noise in Volkswagen Polo's brakes: 1. ABS braking system producing noise: If the vehicle is equipped with an ABS braking system, the noise may originate from this system. This is because the ABS system activates under poor road conditions, making such noises normal in such scenarios. 2. Foreign objects in the braking system: It is advisable to check at a repair shop for any foreign objects that may have entered the braking system, as these can cause noise. 3. Abnormal operation of the brake caliper: The brake caliper pushes the brake pad to create friction against the brake drum for normal braking. The brake caliper is crucial to the braking system, and keeping it clean during daily driving is essential. If not cleaned regularly, accumulated debris can lead to various noises. 4. Excessive wear of brake pads: Brake pads are consumables. Under normal driving conditions, it's recommended to inspect the brake pads every 5,000 kilometers. Whether replacement is needed depends on the specific situation. Excessive wear of brake pads naturally results in noise.
