How many kilograms is 50 liters of gasoline?

50 liters of gasoline weigh between 70 and 78 jin (Chinese pounds). The density of gasoline: 0.70~0.78g/ml. The weight of 50 liters of gasoline = density * volume = (0.70~0.78) * 50 = 35 kilograms~39 kilograms. Related introduction to gasoline: Compression ratio: The primary standard for selecting gasoline grades for cars is the engine's compression ratio, which is also the core energy-saving indicator of contemporary automobiles. The operation of an engine consists of a cyclical movement of the cylinder's "intake-compression-combustion-exhaust-intake" process. The compression ratio is the ratio of the cylinder volume when the piston is at the farthest and nearest points in its stroke. Anti-knock quality: When the piston is about 10 degrees past the top dead center, the combustion generates maximum pressure, pushing the piston with the greatest force. As the speed increases, ignition becomes increasingly advanced. Eventually, a speed is reached where the fuel-air mixture ignites before the spark occurs, which is known as knocking. The gasoline grade determines the timing of the knock point, effectively determining the engine's power output. The anti-knock performance of fuel varies with its composition. The higher the fuel's anti-knock performance, the higher the engine's compression ratio can be, improving both the engine's fuel economy and power performance.

How Many Minutes Is the Most Correct for Warming Up the Car in Summer?

In summer, warming up the car only requires 10 to 30 seconds. Here are the reasons why warming up is necessary: 1. The upper part of the engine lacks oil and lubrication after prolonged parking: After the car has been parked for a long time, the engine oil flows back to the oil pan at the lower part of the engine. Therefore, when starting the engine after not using the car for a while (such as overnight), the upper part of the engine is in a state without oil and lacks lubrication. It takes about 10 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft. 2. The fuel supply system is still at a low temperature and cannot effectively vaporize gasoline completely: Before the engine reaches its operating temperature (approximately between 90-110 degrees Celsius), the fuel supply system, due to its low temperature, cannot effectively vaporize gasoline completely. When gasoline is still in a 'wet' liquid state and not vaporized, it is difficult to ignite and start the engine.

What to Do When Car Paint is Scratched?

Car paint scratches can be categorized into three levels: minor scratches on the body surface, damage to the top coat, and damage to the primer or even deformation. Below are the detailed explanations: 1. Minor scratches on the body surface: If the scratches are only superficial and not deep, they can actually be repaired by waxing. 2. Damage to the top coat: If the scratches are deeper and part of the top coat has been scraped off but the primer and deformation are not affected, you can restore the paint by doing a touch-up yourself. A simple and quick method is to purchase a touch-up paint pen and follow the tutorial to apply the paint. 3. Damage to the primer or even deformation: If this is the case, it indicates that the scratches are very severe. If not treated promptly, they may develop into rust later. To repair the primer and deformation, the corresponding area of the car paint needs to be sanded off, followed by metal sheet repair, and finally, repainting with various layers of paint.
