Is it possible to refuel without turning off the engine?

Refueling without turning off the engine is not allowed. The flash point of gasoline is only 50 degrees Celsius, and when the temperature reaches this point, gasoline can flash and explode, which is extremely dangerous. The reasons are as follows: 1. Risk of short circuits or electrical leaks: When refueling, if the vehicle is not turned off, the engine continues to run at high speed. The engine's operation inevitably involves electrical current flow, and any short circuit or electrical leak can be highly hazardous. 2. Exhaust may contain sparks: While the engine is running, the vehicle's exhaust pipe continuously emits exhaust gases, which may sometimes contain sparks, posing a threat to the safety of the gas station. Therefore, it is strictly prohibited to let the fuel nozzle come into contact with the vehicle's exhaust pipe during refueling at a gas station. 3. Vehicle generates significant heat: The engine produces a large amount of heat, which further increases the rate of fuel evaporation. During refueling, the concentration of fuel vapor and air mixture around the fuel tank increases accordingly. Since this mixture is denser than air and does not disperse easily, when the concentration of fuel vapor reaches a certain level, any spark generated by the running engine could ignite and cause an explosion.

What are the faults and causes of excessive fuel pressure?

Common causes include: clogged fuel injectors, poor sealing, or fuel spraying in a linear pattern. Common faults: 1. Fuel injector malfunction: Uneven fuel injection or poor atomization, leading to unbalanced power output from each cylinder. Common causes include: clogged fuel injectors, poor sealing, or fuel spraying in a linear pattern. 2. Fuel pressure malfunction: Low fuel pressure results in poor atomization or linear fuel spray, and in severe cases, only fuel droplets are sprayed, reducing the fuel injection quantity and causing the mixture to become too lean. High fuel pressure increases the actual fuel injection quantity, causing the mixture to become too rich. Common causes include: clogged fuel filter; clogged fuel pump screen; insufficient fuel pump capacity; weak fuel pump safety valve spring; deformed fuel inlet pipe. 3. Incorrect fuel injection quantity: Faulty sensors or circuits cause the control unit to issue incorrect commands, leading to incorrect fuel injection quantities and resulting in a mixture that is too rich or too lean, which is an indirect cause of unstable idle. Specific causes include: faulty air flow meter (or intake manifold pressure sensor); faulty throttle position sensor; faulty throttle idle switch; faulty coolant temperature sensor; faulty intake air temperature sensor; faulty oxygen sensor.

Is driving at 120 km/h in the innermost lane of the highway considered speeding?

On the highway, driving at 120 km/h in the middle (or right) lane is not considered speeding for small vehicles, but it is considered speeding for large passenger vehicles and freight trucks. The specific speed limits should be based on the local highway signs. Additional details are as follows: 1. According to Article 11 of the "People's Republic of China Highway Traffic Management Regulations": When motor vehicles are driving normally on the highway, the minimum speed shall not be less than 60 kilometers per hour. The maximum speed for small passenger vehicles shall not exceed 120 kilometers per hour; for large passenger vehicles and freight trucks, it shall not exceed 90 kilometers per hour; and for motorcycles, it shall not exceed 80 kilometers per hour, and they are not allowed to carry passengers. However, when there are speed limit traffic signs or road markings that differ from the above regulations, the signs or markings shall be followed. 2. Article 81 of the "Implementation Regulations of the People's Republic of China Road Traffic Safety Law": When motor vehicles are driving on the highway under low visibility weather conditions such as fog, rain, snow, dust, or hail, the following regulations shall be observed: when visibility is less than 200 meters, turn on fog lights, low beams, marker lights, and front and rear position lights, and the speed shall not exceed 60 kilometers per hour, maintaining a distance of more than 100 meters from the vehicle ahead in the same lane.
