Is the Crankshaft Oil Tank the Engine Oil Tank?
1 Answers
The crankshaft oil tank is not the engine oil tank. The engine oil in a car engine is located in the oil pan at the bottom of the engine, while the crankshaft is positioned above the oil pan. During the actual refueling process, the amount of oil may exceed the calibrated volume. This is because the fuel tank capacity marked by car manufacturers refers to the volume from the bottom of the tank to the safe fill level. There is still some space from the safe fill level to the tank opening, which is reserved to allow for oil expansion when temperatures rise, preventing overflow. If oil is filled up to the tank opening during refueling, the actual refueling amount will exceed the marked tank capacity. Methods to open the fuel tank: Mechanical key opening: This is commonly found in some rugged off-road vehicles. Most modern family cars no longer use this method as it is relatively complicated. In-car switch method: The position of the in-car fuel tank switch varies among different car models. It may be located on the floor near the driver's seat, on the left front door panel, or on the center console, usually marked with a fuel pump icon. However, it's important to note that the in-car switch can easily lead to the driver forgetting to turn off the engine before refueling. Therefore, drivers should always remember to turn off the engine before refueling. Press-to-open method: The press-to-open fuel tank door is currently the most convenient method. The driver only needs to park the car, and the fuel attendant can press to open the tank for refueling. However, when not parked for refueling, drivers should always lock the central control to prevent the fuel tank cap from being opened.
