When encountering such a situation while driving, promptly stop to inspect, place the triangular warning sign, turn on the hazard lights to alert passing vehicles. If the crankshaft oil seal is found to be leaking engine oil severely, immediately add some engine oil to the crankcase and then quickly drive the car to the nearest repair station. Upon arrival at the repair facility, if replacement parts are available, promptly replace the crankshaft oil seal. Reasons for oil seal leakage: 1. The parallelism between the oil seal pressing surface and the rear oil seal seat installation surface does not meet technical requirements: This was not detected at the time. After the engine has been in use for a while, the lip of the rear oil seal deforms due to uneven force, causing the oil seal to fail and leak oil. This is the most common type of oil leakage. 2. Natural aging of the oil seal after prolonged engine use: Cracks develop at the lip, leading to oil leakage. This is a relatively normal aging phenomenon for crankshaft oil seals.

How is Fatigue Driving Determined for Private Vehicles?

Continuous driving of a motor vehicle for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes is considered fatigue driving. The following are the hazards of fatigue driving: 1. Impact on driving: When a driver is fatigued, their judgment declines, reactions slow down, and operational errors increase. When a driver is mildly fatigued, they may shift gears untimely or inaccurately. When moderately fatigued, their movements become sluggish, and they may even forget to operate the vehicle. In cases of severe fatigue, drivers often perform actions subconsciously or experience brief episodes of sleep, potentially losing control of the vehicle in serious situations. 2. Risk to road safety: Fatigued drivers may experience blurred vision, back pain, stiff movements, swollen hands or feet, lack of concentration, slow reactions, incomplete thinking, mental distraction, anxiety, or irritability. If they continue to drive under these conditions, it may lead to traffic accidents.

Why is there gasoline in the carbon canister?

Carbon canister contains gasoline because the pipeline connected to the solenoid valve at one end of the carbon canister is disconnected, and the car is started and slowly accelerated. A plastic film is placed at the solenoid valve pipe opening to check for suction, or there is a defect in the fuel tank design of the car. No measures were taken to prevent overfilling during the design, which eventually led to liquid gasoline entering the carbon canister through the conduit. Here is more information about the carbon canister: 1. The role of the carbon canister: The carbon canister is part of the vehicle's gasoline evaporation control system and is installed between the fuel tank and the engine. The carbon canister's function is to introduce vapor into the engine cylinder for combustion and prevent it from volatilizing into the atmosphere. 2. Symptoms of carbon canister failure: When the carbon canister fails, the vehicle may exhibit symptoms such as abnormal noise while driving, jerking when stepping on the accelerator, severe fuel odor inside the car, unstable engine idle, lack of power during acceleration, engine prone to stalling, and difficulty starting the car.

Why does the anti-theft light keep flashing after locking the car?

After locking the car, the anti-theft light keeps flashing to inform the owner that the vehicle's anti-theft system has been activated. The following is a detailed introduction to the reasons why the anti-theft light keeps flashing after locking the car: 1. Working status: It indicates that the vehicle's anti-theft system is activated. 2. Power consumption: If the car's engine anti-theft light flashes at a frequency of once every 1 to 2 seconds, it is normal. This means that the car's engine has entered the anti-theft state, and the engine anti-theft system has started to work. This is a normal phenomenon, and the owner does not need to deactivate it. Moreover, the power consumption is minimal, and it poses no problem for the battery. If the battery runs out of power, the vehicle's anti-theft system will lock the car, making it impossible to deactivate the anti-theft system with the remote control, open the door, or start the engine. In this case, you need to use the mechanical key to open the car and either jump-start or replace the battery.
