BMW 5 Series requires fuel with an octane rating of 95 or higher. The fuel grade is classified based on the octane number, which indicates the fuel's anti-knock properties. Iso-octane has excellent anti-knock performance and is assigned an octane value of 100, while n-heptane has poor anti-knock properties and is prone to engine knocking in gasoline engines, thus assigned an octane value of 0. Higher fuel grades offer better anti-knock performance, and the appropriate fuel grade should be selected according to the engine's compression ratio. The BMW 5 Series is a mid-to-large luxury sedan under the BMW brand, with dimensions of 4998mm in length, 1901mm in width, and 1559mm in height, and a wheelbase of 3108mm. The seats and door interiors of this vehicle are adorned with premium Dakota leather, exuding an elegant and sophisticated ambiance. Additionally, it features an 8-inch screen mounted on the back of the front seats and a refrigerator compartment in the center of the rear seats.

What is the fuel tank capacity of the Nissan NV200 in liters?

The fuel tank capacity of the Nissan NV200 is 55 liters. This data is officially released, and owners who have purchased the Nissan NV200 can also check it on the vehicle's configuration sheet. The recommended fuel grade for the Nissan NV200 is 92 octane, with a fuel consumption of 6.9-7.5L per 100 kilometers. A full tank can provide a driving range of approximately 733-797 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is the volume from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to ensure that the fuel inside the tank can expand when the temperature rises without overflowing. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked tank capacity.

Why is the wiper still moving when turned off?

The reasons why the wiper is still moving after being turned off are: 1. Poor circuit contact; 2. Damaged combination switch; 3. Faulty wiring of the wiper motor. The wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to clear rain, snow, and dust on the windshield that obstructs the view. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high, as it uses a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.
