You can turn on the wiper. Here are some precautions for driving test subject two on rainy days: 1. Adjust your mindset: The most important thing for a rainy day test is your mindset. When encountering rain during the test, you must not have negative emotions or be overly nervous. Therefore, candidates must adjust their mindset during the test, maintain an optimistic mood, and not let the weather affect them. 2. Preparations before getting in the car: The rearview mirror may become blurry in the rain, so candidates must wipe the rearview mirror clean before getting in the car to avoid unclear visibility during the test. Before getting in the car, candidates should shake off mud and water from their feet to prevent slipping when stepping on the pedals. Driving in the rain makes the wheels prone to skidding. Therefore, during the test, candidates should control the speed of the car, which should be slower than during normal training. 3. Braking: Brake pads are prone to skidding in the rain, so when braking, you should apply slightly more force than usual. 4. Turning on the wiper: Generally speaking, not turning on the wiper does not have a significant impact on the test. However, it should be noted that before stopping at the designated point on the slope, turn on the wiper to clean the rainwater on the front windshield, then turn it off to prepare for the designated stop.

What is the working process of an automotive air conditioning system?

Automotive air conditioning system working process is: 1. Compression process: The compressor sucks in low-temperature and low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature and high-pressure gas, which is then discharged from the compressor. 2. Heat dissipation process: The high-temperature and high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and releases a large amount of heat. 3. Throttling process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, where its volume increases, and its pressure and temperature drop sharply, exiting the expansion device in a mist form. 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During the evaporation process, it absorbs a significant amount of surrounding heat, and then the low-temperature and low-pressure refrigerant vapor re-enters the compressor. This working principle cycle repeats continuously, thereby reducing the temperature of the air around the evaporator.

How to Determine Which Gasoline Grade to Use for a Car?

Methods to check the gasoline grade for a car: 1. Refer to the car's user manual, which records the recommended gasoline grade for the car. 2. The fuel cap usually indicates the fuel grade, recommending which gasoline grade to use and which is optimal. Below is relevant information about gasoline: 1. Currently, in China, the national (IV) gasoline grades include three types: 90, 93, and 97. The national (V) grades are 89, 92, and 95 (with 98 available in the appendix). Gasoline grades are classified by octane rating. 2. If a high-compression engine uses a low-grade gasoline, it can cause a sharp rise in cylinder temperature, incomplete combustion of gasoline, severe engine vibration, resulting in reduced power output, damaged components, increased fuel consumption, and poor driving performance. 3. If a low-compression engine uses a high-grade gasoline, it may lead to "delayed ignition," meaning the auto-ignition point is not reached even at maximum compression, resulting in incomplete combustion, which is also not beneficial for the engine.

Why is the Wuling Hongguang called the 'God Car'?

There are four reasons why the Wuling Hongguang is called the 'God Car': 1. Sales Myth: Forbes stated that the Wuling Hongguang saved General Motors. While GM's best-selling vehicle in the U.S. is the pickup truck, its sales still fall short of one-tenth of the Hongguang's. The unassuming Wuling is the best-selling car in China to date, with almost one car sold every six seconds. 2. Excellent Driving Experience: It features a rear-wheel-drive and front-engine layout similar to the Cadillac ATS and BMW 3 Series, offering such impressive handling that it even has the potential for drifting and tail slides. 3. Powerful Engine: The Wuling 1.5L inline 4-cylinder naturally aspirated engine delivers an impressive 112 horsepower and 147 N·m of torque. Paired with a 5-speed manual transmission, just a slight increase in RPM results in explosive power response and acceleration. 4. Affordable Price: Forbes noted that the Wuling Hongguang is the best-selling car in human history. Whether in rural or urban areas, the Wuling Hongguang is ubiquitous. Chinese people use it to support their small businesses, transport goods, and even carry refrigerators, helping generate tens of billions of yuan in wealth annually.

How long after window tinting can ETC be installed?

It is recommended to wait one month after applying window tint before installing the ETC device, as the tint film on the windshield typically requires a month to fully dry and cure. Installing the ETC before the film has completely dried may cause localized peeling. However, some brands of tint film may fully dry within about a week, so the actual waiting period should be determined based on the specific situation. Below is additional information: ETC installation and activation steps: 1. Attach the ETC electronic tag: Clean the windshield (the area where the tag will be placed), then peel off the adhesive backing of the ETC tag and firmly attach the device to the upper part of the windshield. 2. Insert the card: Insert the card into the tag, then remove and reinsert it twice until the screen displays "Bluetooth enabled." If the tag shows "Tag invalid" before installation, this is normal and does not affect activation. 3. Activate the tag: Turn on your phone's Bluetooth, open the mini-program, navigate to the activation page, wait for the Bluetooth connection, and finally upload photos of your vehicle. Once activation is successful, the process is complete. Note that activation methods may vary depending on the ETC card. For self-installation, refer to the device's instruction manual for specific details.

Can ETC cards still be stolen?

ETC cards have the risk of being stolen, so it is recommended to remove the ETC card when parking to prevent theft. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front that has stopped, to prevent the ETC device of the vehicle in front from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The ETC lane recognition speed is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also lead to a failed deduction. Unauthorized disassembly or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to become invalid. It can be sent to the bank where the ETC card was processed or the highway service office for testing. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card to bind with ETC, insufficient balance will also lead to a failed deduction. You can follow the guidance of the on-site staff to go to the manual MTC lane and use cash or card to pass. Poor sensing due to overly thick car windshield. Especially for vehicles that have undergone repairs or replacement of the windshield after an accident, or for those who have modified the front windshield, extra attention is needed.

What engine is used in the 2019 National VI Sylphy?

The engine of the 2019 National VI Sylphy is jointly produced by Nissan and Dongfeng, manufactured at Dongfeng Nissan's Huadu Engine Factory, and is classified as a domestically produced engine. The 2019 National VI Sylphy 1.6L version is equipped with the HR16DE engine, delivering a maximum horsepower of 126, a maximum power of 93kW, and a maximum torque of 168Nm. The 1.8L version features the MRA8 engine, with a maximum horsepower of 139, a maximum power of 102kW, and a maximum torque of 174Nm. For daily maintenance of the 2019 National VI Sylphy engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may rupture or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
