What does it mean for the car body to sweep the line in Subject 2?

In Subject 2, 'car body sweeping the line' means the car body crosses the line. During the Subject 2 test, if the car body crosses the line, 100 points will be deducted, resulting in a failed test. In addition to the car body crossing the line, other actions that will deduct 100 points include failing to park properly in reverse, stopping midway, not following the prescribed route or sequence, and exceeding the allotted time. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, deduction of 20 points, deduction of 10 points, and deduction of 5 points. The test is considered passed if the following conditions are met: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If the Subject 2 test is failed, the applicant can retake the test once on the spot. If the applicant does not take the retest or fails the retest, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of test appointments for Subject 2 and Subject 3 road driving skills tests must not exceed five. If the fifth test appointment still results in failure, the scores of other previously passed subjects will be invalidated.

How many kilometers should a new car run before breaking in on the highway?

The break-in mileage for a car is generally between 1,000 to 2,500 kilometers, while imported cars may require a longer distance, typically between 1,500 to 3,000 kilometers. The break-in period is divided into three stages: the initial 100 kilometers, the early break-in phase of 200 kilometers, and the formation of an oxidation film at 3,000 kilometers. Here is some relevant information: 1. Precautions during the break-in period: Avoid emergency braking during the break-in period, as it can impact the braking system. Also, avoid overloading the new car, as running it at full capacity during the break-in period can damage the components. Additionally, avoid long-distance trips during the break-in period, as prolonged engine operation can lead to increased wear on the components. 2. Concept of the break-in period: Before assembly, each moving part of the car is individually manufactured, and there may be geometric deviations in the machining process. As a result, some moving parts may have direct contact in certain areas after assembly, making it difficult for lubricating oil to reach the friction surfaces, leading to early wear. The break-in period is the time required to wear down these direct contact points, and this period is called the break-in period.

Why is the Used Jaguar XF So Cheap?

One reason is the relatively low resale value of the Jaguar brand. Additionally, in my opinion, it's related to the product's reputation, stability in quality, the relatively high refurbishment and maintenance costs for used cars, as well as the fact that the previous-generation XF remained unchanged for many years before domestic production. From an appearance perspective, models before 2015 look quite similar, but their prices are also very low. Here is some extended information: 1. Model: As Jaguar's mid-to-large luxury sedan, it is divided into the standard version, the estate version, and the XFR performance version. In terms of design, the Jaguar XF leans more towards the XK's car-making philosophy, exuding a modern feel: a bold front grille, sleek body lines, complemented by the leaping jaguar emblem embedded in the center of the grille, highlighting the car's extraordinary presence. The interior of the Jaguar XF is very spacious, easily accommodating five adults, complementing its exterior style. 2. Craftsmanship: The XF also boasts exquisite craftsmanship, offering a prestigious driving experience. Furthermore, the sequential shift system provides the driver with one-touch manual shifting via paddle shifters on the steering wheel; drivers can choose from 21 shift modes to match throttle progression and shift strategy with actual road conditions and driving environments.

Is It Necessary to Use Fuel Cleaner for a New Car?

It is not necessary to use fuel cleaner for a new car. Fuel additives are mainly used to clean carbon deposits in the fuel injectors and intake valves, protect the engine, reduce wear, lower emissions, decrease fuel consumption, and restore power. They can be added when the mileage reaches around 50,000 to 60,000 kilometers. The relevant introduction to fuel additives is as follows: Functions of Fuel Additives: Fuel additives, commonly known as the third generation of gasoline detergents (also referred to as gasoline detergents or fuel additives), are designed to address carbon deposit issues in the fuel system of electronically fuel-injected vehicles, quickly restore the engine to optimal performance, and compensate for certain deficiencies in gasoline properties while imparting new beneficial characteristics (such as improving atomization, reducing wear, protecting the engine, and lowering emissions). Composition of Fuel Additives: Fuel additives are primarily composed of more than ten ingredients, including nano-molecules, cleaning activation factors, antioxidants, anti-corrosion agents, and demulsifiers. They are specifically developed to target harmful components in fuel, such as sulfur, gum substances, and engine carbon deposits, thereby enhancing power, promoting combustion, providing anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubricating effects.

Why does the vehicle idle speed suddenly increase?

Vehicle idle speed increases due to faults in the engine intake system and fuel system. Here are the relevant explanations: 1. In the engine intake system, components such as the throttle body assembly, air flow sensor, engine intake pipe, engine vacuum tube, and engine exhaust gas recirculation valve may be damaged. 2. Throttle body assembly: The throttle controls the air entering the engine, acting as a controllable valve. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Simply put, it functions similarly to a human throat. If this component fails and the throttle opening becomes uncontrolled, the throttle opening increases, causing the vehicle's idle speed to suddenly rise. 3. Air flow sensor: It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU) as one of the basic signals for determining fuel injection. It is a sensor that measures the air flow entering the engine. If this component fails, the vehicle's ECU will inaccurately determine the amount of air entering the engine. Since the ECU cannot accurately judge the air intake, the vehicle may exhibit a sudden increase in idle speed. Engine vacuum tube: This component maintains the engine's vacuum level to ensure smooth operation. If the vacuum tube is damaged, the internal vacuum level of the engine becomes unstable. To maintain normal engine operation, the ECU will increase the engine speed, resulting in a sudden rise in the vehicle's idle speed.
