The reason is that the gear shaft of the wiper motor is rusted, causing the first gear to fail to rotate, and the plastic gear will quickly wear out and become unusable. Additionally, the circular contact plate paired with the gear may also rust, leading to poor contact in the first gear of the wiper, preventing it from rotating. Here are some extended details: 1. Wiper: The wiper is a plastic product. Parking the car in a shaded area can help extend the lifespan of the wiper. A good wiper must have characteristics such as heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, the ability to fit the windshield, reduce the burden on the motor, low noise, strong water repellency, and softness to avoid scratching the windshield, ensuring clear visibility for the driver. 2. Types of wipers: There are roughly two types of wipers. One is the traditional intermittent type, which is the most common wiper, available in three to four segments, allowing the driver to adjust according to the rain intensity and visibility conditions. The other type is the rain-sensing wiper, mostly used in mid-to-high-end vehicle models.

What is the safe distance between cars in urban areas?

There is no absolute standard, only speed-dependent standards. The introduction to safe driving distances is as follows: 1. High-speed driving: When the speed is above 100km/h, the safe distance should be more than 100 meters. 2. Fast driving: When the speed is above 60km/h, the safe distance is numerically equal to the speed; for example, at 80km/h, the safe distance is 80 meters. 3. Medium-speed driving: When the speed is around 50km/h, the safe distance should not be less than 50 meters. 4. Low-speed driving: When the speed is below 40km/h, the safe distance should not be less than 30 meters. 5. Crawling speed: When the speed is below 20km/h, the safe distance should not be less than 10 meters.

How to Start the Engine After Stalling a Manual Transmission Car?

To start the engine after stalling a manual transmission car, simply press the brake, shift the gear lever to neutral, engage the handbrake, and release the clutch pedal before starting. The key to preventing stalling is mastering clutch control and gear shifting. Below are relevant explanations: 1. Speed and Gear Selection: During driving, use lower gears for slower speeds and higher gears for faster speeds. Mismatching speed and gear can cause stalling, increase fuel consumption, and potentially damage vehicle components over time. 2. Clutch: The clutch is located within the flywheel housing between the engine and transmission, secured to the rear plane of the flywheel with screws. The clutch's output shaft serves as the transmission's input shaft. While driving, the driver can depress or release the clutch pedal as needed to temporarily disconnect or gradually reconnect the engine and transmission.

Should You Depress the Clutch When Making a U-Turn?

You do not need to depress the clutch when making a U-turn. Here are the details: 1. Consequences of depressing the clutch during a U-turn: Depending on the actual situation, it is best not to depress the clutch during a U-turn; instead, only apply light braking. If you depress the clutch during a U-turn and encounter an emergency, it may cause the vehicle to stall. 2. Techniques for making a U-turn using forward motion alone or a combination of forward and reverse motion: (1) Forward U-turn: If conditions permit and the road is wide, you can use a large detour method to make a U-turn. In areas with traffic control personnel, you can first signal your intention to make a U-turn, and after receiving permission, reduce speed, shift to a lower gear, honk the horn, and proceed slowly to complete the U-turn. (2) Combination of forward and reverse motion U-turn: If the road is too narrow to complete the U-turn in one forward motion, you can use a combination of forward and reverse motions. Choose a safe section of the road, signal a left turn, and when the front wheels are close to the roadside or the front of the vehicle is near an obstacle, depress the clutch, lightly press the brake pedal, and before the vehicle comes to a complete stop, quickly turn the steering wheel fully to the right to redirect the front wheels for reversing. Then, immediately stop the vehicle firmly. 3. Precautions for making a U-turn: When there is no 'No U-Turn' sign, you can make a U-turn as long as it does not affect normal traffic and safety is ensured. Generally, the central divider on roads will change from a solid line to a dashed line near intersections. You can also make a U-turn on yellow grid lines where there is no central barrier.

What does the trip on the car dashboard mean?

Car dashboard trip represents the trip mileage, the following is the introduction of related content: 1. Record: It can be used to record the mileage of each trip by the user. 2. Meaning: The left side represents the total mileage of the car. Press the switch button next to the trip number to randomly measure the mileage from point A to point B. For example, if you want to know the distance from home to the company, switch the odometer to trip before starting, and it will automatically count during driving. The number when you park at the company is the mileage. 3. Composition: The speedometer actually consists of two meters, one is the speedometer, and the other is the odometer. 4. Mode: The traditional speedometer is mechanical. A typical mechanical odometer is connected to a flexible shaft, which has a steel cable inside. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, and the steel cable drives a magnet inside the odometer cover to rotate.

What is the fuel consumption of the new Qashqai?

The comprehensive fuel consumption of the new Qashqai is 6.2-6.4L/100km. There are currently 4 models of the new Qashqai on sale. Among them, the Luxury Edition, Luxury Pilot Edition, and Smart Edition have a comprehensive fuel consumption of 6.2L/100km. The Flagship Edition has a comprehensive fuel consumption of 6.4L/100km. The above figures are NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.9-8.5L/100km. When driving, the following 5 tips can help reduce fuel consumption: 1. When starting the vehicle, use a low gear, gently press the accelerator, and accelerate slowly. Avoid suddenly stomping on the accelerator, as this can multiply fuel consumption. 2. Gentle acceleration and braking, early braking: While driving, press the accelerator gently to avoid sudden increases in engine RPM and prevent the car from shaking during operation, making it more fuel-efficient. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. 3. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. 4. Regular vehicle maintenance or checks: Timely oil changes can reduce carbon buildup (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter when dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage. 5. Close windows while driving. Driving with windows open increases wind resistance. The greater the wind resistance, the more resistance the car encounters, requiring more power and thus increasing fuel consumption.

What does it mean that gasoline cars cannot add diesel?

What it means that gasoline cars cannot add diesel is that gasoline cars should be fueled with gasoline, and diesel cars should be fueled with diesel—gasoline cars must not be fueled with diesel. The reasons why gasoline cars cannot add diesel are as follows: Gasoline has a low carbon content, while diesel has a relatively high carbon content, and their densities also differ significantly. The relationship is similar to that between light water and heavy water, with gasoline and diesel being analogous to light oil and heavy oil, respectively. Compared to gasoline, diesel has a lower ignition point and is less volatile, while gasoline has a higher ignition point and is more volatile. In a gasoline engine, when the fuel injector sprays gasoline and the air entering through the throttle valve forms a mixed gas that enters the cylinder, diesel may ignite before the spark plug fires, causing abnormal pressure in the combustion chamber and resulting in knocking. Additional information on the consequences of adding the wrong fuel: 1. The fuel injector pressure in gasoline engines is lower than that in diesel engines. When diesel is added, it cannot be fully atomized, leading to incomplete combustion, resulting in engine power loss, unresponsiveness to throttle input, and the emission of black smoke from the vehicle. 2. Diesel has a low ignition point and may combust violently on its own before the spark plug fires, causing abnormal pressure in the combustion chamber, commonly known as knocking, which poses significant safety hazards.
