What Causes Engine Noise During Cold Start in Geely Vision?

What is the reason for the difficulty in engaging the downshift of Fast Transmission?

If the main box of the transmission is equipped with a synchronizer, it may be due to a damaged synchronizer. If the main box does not have a synchronizer, it could be due to improper operation during shifting, which is not a major issue. The transmission is a double countershaft transmission, and generally, there will be noise when engaging gears during startup. When shifting up or down, the double-clutch method should be used. When downshifting, the clutch should be depressed to disengage the gear, then the clutch pedal should be released to add empty throttle, and then the clutch should be depressed again to engage the gear. This is a continuous action. The following are relevant details about Fast Transmission: 1. Convenience: The working principle of Fast Transmission is to automatically shift gears based on factors such as vehicle speed, engine speed, and power load. Fast Transmission does not require the driver to operate the clutch for shifting, making it very convenient to use. Especially when driving on crowded urban roads, the automatic transmission demonstrates excellent convenience. 2. Complexity: The automatic transmission of Fast Transmission is much more complex than a manual transmission, with many differences, but the biggest difference lies in control. A manual transmission is operated by the driver, with gear shifting performed manually, while an automatic transmission is controlled by the machine, with gear changes performed by hydraulic control devices.

What is the standard width of a road surface?

For multi-lane highways above Class III, the width of each motor vehicle lane is 3.5 to 3.75 meters. Below are the specific details: 1. Median strip: There is no uniform standard for the central median strip, as it is designed according to local conditions. A simple cement central median strip is one meter wide (the distance between the two white solid lines on both sides of the central median strip). For central green median strips, there is no unified standard for width, and some "image projects" can have median strips as wide as several tens of meters. 2. Sidewalk: Urban arterial roads must have sidewalks. The width of sidewalks on urban arterial roads is calculated based on actual pedestrian flow, generally at least 3 meters wide, with wider ones reaching 15-20 meters. 3. Lane: The width of each lane on urban roads is 3.5 meters. The width of each diversion lane at intersections is 2.3-2.5 meters. The width of each lane on trunk roads (including expressways) is 3.75 meters, and the shoulder (emergency stopping lane on expressways) is 1.5-2.5 meters. Lane width refers to the width required for a single line of vehicles to travel safely and comfortably, including the external width of the design vehicle and the necessary clearance for passing, overtaking, or parallel driving.

Is it mandatory to display the compulsory insurance label on the windshield now?

Currently, it is mandatory to display the compulsory insurance label on the windshield. The details are as follows: 1. According to the relevant regulations of the 'Road Traffic Safety Law of the People's Republic of China': If a motor vehicle driven on the road does not display the insurance label, the traffic management department of the public security organ shall detain the vehicle, notify the party to provide the corresponding license, label, or complete the necessary procedures, and may issue a warning or impose a fine ranging from 20 to 200 yuan. If the party provides the corresponding label or completes the necessary procedures, the vehicle shall be returned promptly. 2. The role of electronic insurance policies: With the introduction of electronic insurance policies for auto insurance, if electronic policies are implemented locally and the insurance company and traffic management department have achieved interconnection and sharing of compulsory insurance information, not displaying the paper label generally will not result in a penalty. However, if electronic policies are only in the pilot phase locally and the insurance company and traffic management department have not yet achieved interconnection and sharing of compulsory insurance information, it is still necessary to display the paper label on the windshield. Therefore, whether not displaying the compulsory insurance label will result in a penalty depends on the official statement of the local public security and traffic management department!

Fuel consumption of the Kia K3?

The currently available Kia K3 models on the market come in three displacement options: 1.5L, 1.4L, and 1.6L. According to the combined fuel consumption data from the Ministry of Industry and Information Technology, the fuel consumption for these three displacements of the Kia K3 is 5.1L/100km, 5.3L/100km, and 6.2L/100km, respectively. However, based on actual measured data from some Kia K3 owners, the fuel consumption generally hovers around 7L/100km. Below are specific methods to reduce fuel consumption: 1. Gentle acceleration: When starting at low speeds, the car enters a peak fuel consumption zone. Therefore, gently pressing the accelerator during startup prevents excessively high RPMs, effectively reducing fuel consumption. 2. Avoid high RPMs: Try to avoid unnecessary high RPMs, as fluctuating engine speeds can significantly increase fuel consumption. 3. Regular maintenance: Regularly change the engine oil and remove carbon deposits. 4. Avoid sudden braking: Anticipating road conditions in advance and avoiding sudden braking not only enhances driving safety but also saves fuel. For example, gradually slowing down before traffic lights and utilizing inertia to coast.

How Many Meters Away from a Car Charging Pile is Radiation-Free?

There is no radiation at a distance of more than 2 meters from a car charging pile. Below is some information about the radiation from charging piles: 1. Safety: The electromagnetic radiation generated by electrical appliances has no significant impact on the human body (sunlight, which we encounter daily, is a form of electromagnetic radiation), as the intensity of electromagnetic radiation is limited by safety standards. Ionizing radiation has a greater impact on humans (such as the commonly referred to nuclear radiation), but it also naturally exists at certain intensities, and there is no need for concern in normal daily life. 2. Radiation Intensity: First, let's look at the national standard regulations. For low frequencies between 1~8 Hz, the permitted public exposure values are: electric field strength of 8000V/m and magnetic field strength of 500A/m. This means that any intensity below these values is considered acceptable. Taking commonly used Guoxuan lithium-powered buses and BYD K-series electric buses as examples, the measured electric field strength is 1~2V/m, and the magnetic field strength is 2~4A/m. When the vehicle speed exceeds 40km/h, the electric field strength inside the cabin is below 1A/m, and the magnetic field strength is below 0.05A/m. These values are so small that they are negligible, far lower than those of a typical smartphone.

How to Shift to 1st, 2nd, 3rd, 4th, and 5th Gears?

Generally, start in 1st gear, then shift to 2nd gear after driving a few meters. When the speed reaches above 20 mph but below 35 mph, shift to 3rd gear. When the speed exceeds 35 mph but is below 45 mph, shift to 4th gear. If the speed goes beyond 45 mph, shift to 5th gear. Below are some related details: 1. Gear Shifting Precautions: If you notice the vehicle shaking while driving, it indicates the engine is operating at low speed with high load. Immediately downshift by one or two gears based on the actual situation. When shifting gears, coordinate the clutch and accelerator properly—press the clutch pedal fully, release the accelerator pedal, and quickly shift to the corresponding gear. After shifting, release your hand promptly and avoid keeping it on the gear lever (commonly called the gear stick) for too long, as this may damage it. 2. Special Methods for Reverse Gear: Different vehicles have different ways to engage reverse gear. Some require pushing straight to the right and then pulling down to engage; others position reverse gear further left than 1st gear, meaning you need to push left one more notch beyond 1st gear and then shift forward. Some vehicles require lifting the button under the gear stick with the middle and ring fingers, then pushing left and forward to engage reverse gear. Others need the gear stick to be pressed down before pushing left and forward or right and backward to engage reverse gear.
