According to the theoretical calculation of chemical reactions, 1 kg of gasoline can completely burn up to 14.7 kg of air, so the ideal air-fuel ratio for gasoline engines should be 14.7.

Diesel is a hydrocarbon fuel, with about 86% carbon and 13% hydrogen, and 1% oxygen. This means that 1 kg of diesel can completely burn to produce 43,917.8 kJ of heat.

For example, 22.4 liters of air contains 22.4 x 21% = 4.7 liters of oxygen. Oxygen has a molar mass of 32 grams.

250g/32g/mol=7.8mol, 7.8mol x 22.4/4.7 = 37 mol of air

Reference materials:

Air is a mixture of various gases, including oxygen, nitrogen, argon, and neon. Its composition and volume content is as follows:

1. Nitrogen: 78.09%

2. Oxygen: 20.95%

3. Rare gases: 0.932%

4. Carbon dioxide: 0.034%

5. Water and impurities: 0.002%

To answer the question, 1 kg of gasoline can completely burn up to 14.7 kg of air.
