Methods to determine if fake engine oil has been added mainly include: 1. Observe the oil's appearance: Genuine engine oil is usually much darker in color compared to fake oil, and authentic oil is free of impurities, suspensions, or sediments, appearing light and transparent with better fluidity. 2. Check the packaging: Genuine engine oil packaging is typically well-crafted, with a one-time-use cap and a sealing tin foil at the opening, while fake oil packaging is rough and dull in color. 3. Compare prices: The prices of genuine engine oil are generally similar, while oils with significant price differences may be fake. 4. Smell and skin contact: Genuine engine oil has almost no noticeable odor, whereas fake oil has a distinct, irritating gasoline smell. High-quality oil gives a noticeable warm sensation when applied to the skin, while inferior oil feels noticeably cold when a small amount is applied to the back of the hand.

What is a Hydrogen Fuel Vehicle?

Hydrogen fuel vehicles refer to automobiles that primarily use hydrogen as their energy source for propulsion. In conventional internal combustion engines, diesel or gasoline is typically injected, whereas hydrogen vehicles utilize gaseous hydrogen instead. Fuel cells and electric motors replace the standard engine. The principle of hydrogen fuel cells involves introducing hydrogen into the fuel cell, where the electrons of hydrogen atoms are blocked by a proton exchange membrane, then conducted through an external circuit from the negative to the positive electrode, generating electricity to drive the motor. Additional Information: 1. Hydrogen Fuel Principle: Hydrogen molecules combine with oxygen molecules through combustion to produce thermal energy and water. Hydrogen fuel cells generate electricity by combining liquid hydrogen with oxygen from the air. Based on this principle, hydrogen fuel cells can generate electricity to power vehicles, supply household or industrial electricity, or serve as mobile phone batteries. 2. Hydrogen Storage Methods: There are two traditional hydrogen storage methods. One method involves using high-pressure cylinders (hydrogen tanks) to store hydrogen, but these cylinders have limited storage capacity and pose explosion risks. The other method involves storing liquid hydrogen, but the storage tanks are very large and require excellent insulation devices to maintain temperature.
