What should I do if the car doesn't stall after driving through water?

After driving through water without stalling, the car needs to slow down or stop for observation, driving at low speed and applying the brakes multiple times. After the car has driven through water, even if the vehicle hasn't stalled, it's still necessary to assess the vehicle's condition immediately, such as slowing down or stopping to check whether the engine has been slightly affected by water, and to inspect whether the entire vehicle's electrical circuits have been exposed to water. After exiting the water, drive at a low speed for a distance and gently press the brake pedal several times to allow the brake pads and drums to create friction, which helps evaporate any attached moisture through heat, thereby extending the vehicle's service life. Generally, if the car doesn't stall after driving through water, it indicates that the car is not malfunctioning. This means the water depth did not exceed the air intake, and the exhaust pipe was not submerged in water, which is not a problem. The car's own pressure is sufficient to drain the water, so there won't be a phenomenon of the exhaust pipe sucking back water, and it won't affect driving safety. In real life, after water overflows the exhaust pipe, the car won't stall and can continue moving forward. This is because the gas pressure from the car's exhaust pipe is greater than the water pressure, preventing the gas from being blocked. The real reason a car engine stalls is that when water reaches a certain level and enters the cylinder through the filtration system, it hinders the cylinder's movement, causing the car to shut down, i.e., stall. At the moment of entering the water, try to maintain the vehicle's balance to avoid splashing water onto electrical components or allowing water to enter the engine's intake system. The correct driving method is to first reduce speed and shift to a lower gear, preferably maintaining the engine speed at around 4000 rpm in first gear, keeping the speed steady.

What are the reasons for difficulty in starting the engine after hot shutdown?

The reasons for difficulty in starting the engine after hot shutdown are as follows: 1. Fuel injector leakage: Normally, the fuel injector sprays fuel, but leakage constitutes additional fuel supply. The more severe the leakage, the richer the air-fuel mixture becomes, leading to difficulty in starting when the engine is hot. 2. Damaged carbon canister solenoid valve: During hot starts, fuel atomization is already normal, and additional fuel vapor is unnecessary. If the carbon canister continues to supply fuel vapor to the intake tract, it will cause an overly rich mixture, making it difficult to start. 3. Fuel quality: After the engine is shut down when hot, the engine compartment remains at a high temperature. If the fuel is highly volatile, it can form high vapor pressure in the fuel rail. When this pressure exceeds the fuel system's supply pressure, vapor lock occurs, causing the fuel injector to spray overly lean fuel vapor, leading to starting difficulties. 4. Damaged intake air temperature sensor: The intake air temperature sensor functions similarly to the coolant temperature sensor, both adjusting fuel injection. However, if the coolant temperature sensor fails, it causes cold start difficulties, whereas a faulty intake air temperature sensor results in hot start problems. 5. Engine carbon deposits: Carbon deposits strongly adsorb gasoline. If there are significant carbon deposits on the intake valves, throttle body, or pistons, they can adsorb some fuel, leading to an overly lean mixture and affecting starting. This issue can also occur during cold starts.

What kind of cars can be purchased with a C5 driver's license?

C5 driver's license allows the purchase of automatic transmission passenger vehicles specially designed for the disabled. In practice, these are small or mini automatic transmission vehicles designated for passenger use by individuals with disabilities. The revised "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" by the Ministry of Public Security states that the C5 license is intended to support and facilitate travel for people with disabilities, but it currently does not permit commercial operation. However, local governments in cities like Chongqing and Shenyang have opened up commercial driving opportunities for the disabled to encourage self-reliance. While there are many automatic transmission vehicles available on the market, they are not specifically designed for disabled drivers. Using non-specialized vehicles may result in penalties if discovered by traffic police. Currently, China does not have dedicated manufacturers producing automatic transmission vehicles for the disabled. However, standard automatic transmission cars can be modified at authorized institutions to become legally compliant vehicles for disabled drivers. Eligibility requirements for a C5 driver's license: The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" specifies disability criteria: individuals with right lower limb disabilities, both lower limb disabilities, hearing impairments, missing right thumb, or finger end joint defects are permitted to drive. Among these, those with right lower limb or both lower limb disabilities can apply for a C5 driver's license.

Does 'F' Indicate Full or Empty Fuel Tank?

'F' indicates that the fuel tank is full. On the fuel gauge of a car's dashboard, the characters 'E' and 'F' are used. 'F' stands for full, while 'E' stands for empty. If the fuel gauge needle is at the 'F' position, it means the car's fuel tank is full. If the needle is at the 'E' position, it indicates that the fuel tank is nearly empty. When the car is low on fuel, a warning light will illuminate on the dashboard. The fuel warning light is usually shaped like a fuel tank. When fuel is low, the warning light will turn yellow; if the fuel is critically low, the light will turn red. Some car models only display a yellow fuel warning light, in which case the driver should pay attention to the remaining fuel level and refuel promptly. During refueling, it is not advisable to fill the car's fuel tank completely, especially in hot summer weather. This is because gasoline expands and evaporates into vapor under high temperatures in summer, and the resulting vapor or even liquid can enter the carbon canister for storage. Overfilling the tank can cause the fuel gauge needle to deviate. Even after prolonged use, the fuel gauge needle may not drop, but it will return to normal after some time. Effects of Low Fuel Level: Fuel sloshing leading to engine stalling: When the fuel level is too low, on bumpy or winding roads, the fuel may slosh, and the fuel pump may not be able to pump fuel in time. This can result in insufficient fuel supply, causing the car to experience shaking, jerking, or stalling. Fuel pump overheating: The fuel pump is cooled by the fuel. If the fuel level is too low, the cooling performance of the fuel pump will decrease, accelerating the wear of internal components and potentially leading to short circuits or burning out of the fuel pump. Clogging the fuel system: The bottom of the fuel tank contains more impurities. If the fuel level is too low, these impurities can enter the fuel supply system due to fuel sloshing, leading to clogged fuel lines. Impact on driving safety: Low fuel levels can easily cause the car to stall. If the car stalls while driving, both steering and braking can be affected. If there is heavy traffic on the road, this can easily lead to traffic accidents.
