Should the AOFF in an automatic transmission be kept on or off?

When is the Best Time to Open a Car Sunroof?

Generally, sunroofs are particularly suitable for use during autumn and winter. During these seasons, car windows are usually kept closed due to colder weather, leading to trapped unpleasant odors inside the vehicle. Opening the sunroof at this time can quickly expel these odors. More details are as follows: 1. The best seasons to open a sunroof: When the weather transitions into late autumn and winter. Ventilation is needed inside the car, but opening the windows feels too cold. Opening the sunroof at this time can quickly remove stale air from the vehicle. 2. Negative pressure ventilation: When driving on highways, if you want to quickly expel air from the car but the external air circulation is insufficient, opening the sunroof can gradually freshen the air. This method utilizes negative pressure ventilation. The principle is simple: when the car is moving at high speed, air rapidly forms a low-pressure zone around the vehicle, while the interior pressure remains higher than outside. Opening the sunroof allows the interior air to be quickly drawn out by the external airflow. 3. Rapid cooling: During the scorching heat of summer, prolonged exposure to the sun can cause the interior temperature to rise rapidly. Many car owners immediately turn on the air conditioner at maximum power to lower the temperature. For cars with a sunroof, utilizing negative pressure to extract hot air while driving is a simple and quick method that can rapidly reduce the interior temperature by 3-5 degrees, achieving both fuel efficiency and effectiveness.

How to Use Service Brake When Parking a Motor Vehicle on a Downhill Section?

When parking a motor vehicle on a downhill road, the service brake should be applied earlier than on a level road. When driving downhill, the vehicle speed gradually increases due to gravity, resulting in a longer braking distance compared to a level road. Therefore, braking should be initiated earlier. Here is some relevant information: 1. Regarding uphill sections: Braking when parking on an uphill section should be delayed compared to a level road. This is because the vehicle speed naturally decreases due to gradient resistance when driving uphill, leading to a shorter braking distance. Thus, braking should be delayed compared to a level road. 2. Regular driving: During normal driving, the service brake (foot brake) is typically used to slow down and stop while moving forward. Once the vehicle comes to a complete stop, the parking brake (handbrake) should be engaged to prevent the vehicle from rolling forward or backward.

Is Automotive Urea Harmful to the Human Body?

The human body naturally produces urea, so contact with the skin generally does not cause any harm. However, at high temperatures, automotive urea can easily release ammonia gas, which has corrosive properties. Prolonged skin exposure may lead to pigmentation or ulcers. Therefore, if you come into contact with automotive urea, rinse it off with clean water as soon as possible. Below is more information about automotive urea: 1. Function of Automotive Urea: Automotive urea is used in the Selective Catalytic Reduction (SCR) system of diesel vehicles to catalytically reduce nitrogen oxides (NOx) in exhaust gases into harmless nitrogen (N₂) and water (H₂O), which are then emitted. 2. Working Process of Automotive Urea in the SCR System: The SCR system is a closed-loop injection system. When exhaust gases exit the engine combustion chamber, an electric pump draws a sufficient amount of urea solution from the urea tank based on commands from the electronic control unit. The urea solution is mixed and atomized with compressed air before being evenly injected into the exhaust stream through the urea nozzle. Under high temperatures, the urea solution rapidly decomposes into NH₃ (ammonia), which then reacts with NOx in a catalytic reduction process, ultimately producing harmless N₂ and H₂O for emission.

What should be noted before driving a motor vehicle into a highway tunnel?

Before driving a motor vehicle into a highway tunnel, the following points should be noted: 1. Turn on the low beam headlights. Entering a tunnel is equivalent to driving at night, so low beam headlights should be turned on. This is to avoid affecting oncoming vehicles and vehicles ahead. Overtaking is not allowed inside the tunnel unless in emergency situations. 2. Pay attention to traffic signs and speed limit signs before the tunnel. When driving inside the tunnel, a strong sense of speed may be experienced. Do not panic in this situation; appropriately reduce speed and focus your eyes on the far end of the road. 3. Observe the situation ahead in your lane in advance and avoid changing lanes arbitrarily. Then enter the tunnel lane, noting that lane changes are not allowed inside the tunnel. There is no problem when exiting the tunnel; you can turn off the headlights during the day and then drive at the prescribed speed.
