Oil is a kind of oil that we use in our daily cars. Gasoline is of course very harmful to the body. When refueling at a gas station, Encyclopedia Knowledge Network would like to remind everyone: try to keep children and the elderly away from the refueling area to minimize the impact and harm to the body.

Is the smell of gasoline harmful to the human body?

Gasoline is a kind of oil that we use in our daily cars. Gasoline is of course very harmful to the body. Gasoline contains a lot of lead, and gasoline vapor is no exception. Lead is very harmful to the human body. It is easy to cause hyperactivity in children, and it is easy to cause organ damage in teenagers. The elderly are prone to Alzheimer's disease, and it will also affect the skin. It causes damage in all aspects, so you must reduce the inhalation of gasoline. People who work in gasoline cars are better to wear masks and drink plenty of water to help detoxify.

Why does mango smell like gasoline?

The aroma of mango contains unique triglycerides, which makes some overripe mangoes smell a bit like paint. Generally speaking, our body obtains triglycerides after taking in sugar, fat and other foods. The body synthesizes triglycerides and stores them in adipose tissue to meet the needs of fasting and hunger. If you eat mangoes, you will directly ingest triglycerides from mangoes. The amount of vitamin C contained in mangoes is higher than that of ordinary fruits. Every 100 grams of mango contains 23.00 mg of vitamin C). The content of vitamin C in mangoes is second only to the vitamin C content of kiwi fruit (62.00 mg per 100 grams).

Therefore, mango is known as the "king of tropical fruits". In addition, mango has a special taste, which comes from the triglycerides contained in mango, and the taste is stimulating.

What is the difference between high and low gasoline grades?

The gasoline grade is determined by the octane number of the gasoline. The higher the octane number, the stronger the anti-knock ability of the gasoline, and the higher the grade. The anti-knock index of gasoline is called the octane number, which is the gasoline grade. Generally, a high compression ratio engine chooses a higher gasoline grade, and a low compression ratio engine chooses a lower gasoline grade, so as to ensure the normal operation of the car.

When refueling at a gas station, you will find that gasoline grades are high and low. The gasoline grade represents the octane number of the gasoline. The higher the octane number, the stronger the anti-knock ability of the gasoline. However, the gasoline grade does not mean that it is more fuel-efficient or of better quality, so when choosing, you also need to judge based on the actual situation of the car engine.

Generally speaking, the operation of an engine consists of repetitive movements of the cylinder: "intake-compression-combustion-exhaust-intake". The ratio of the cylinder volume when the piston is at the farthest point and the closest point of the stroke is the compression ratio. The best way to reduce the fuel consumption cost of a car is to increase the compression ratio of the engine.

Increasing the compression ratio can change the piston stroke. The more the mixed oil and gas are compressed, the greater the reaction of combustion and the more complete the combustion. However, the compression ratio of a car will not be easily changed. It is accompanied by an indicator, which is the anti-knock index of gasoline, called the octane number, which is the gasoline grade.

What does standard gasoline consist of?

Standard gasoline is composed of isooctane and n-heptane. Isooctane has excellent anti-knock properties and an octane number of 100. n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines. Its octane number is 0. Generally speaking, gasoline is marked as 0, which means that the gasoline contains 90% isooctane and 10% n-heptane.
