Stoichiometric ratio isa)Chemically correct air -fuel ratio by weightb...
Stoichiometric ratio is the chemically correct air-fuel ratio by volume. In other words, it is the ratio of air to fuel that is required to completely combust a fuel in an engine. This ratio is based on the chemical reaction between the fuel and air, and it ensures that all of the fuel is burned and converted into useful energy.

Importance of Stoichiometric Ratio
The stoichiometric ratio is important because it determines the efficiency and emissions of an engine. If there is too much fuel in the mixture, the engine runs rich and wastes fuel, which can lead to higher emissions of pollutants. If there is too little fuel, the engine runs lean and can overheat or stall.

Calculation of Stoichiometric Ratio
The stoichiometric ratio can be calculated by determining the mass or volume of air that is required to completely burn a given amount of fuel. This ratio varies depending on the type of fuel being used, as different fuels have different chemical compositions.

For example, the stoichiometric ratio for gasoline is approximately 14.7 parts air to 1 part fuel by volume. This means that for every 14.7 units of air that enters the engine, one unit of gasoline is burned. The exact ratio may vary depending on the specific properties of the gasoline being used.

Conclusion
In conclusion, the stoichiometric ratio is an important concept in engine design and operation. It determines the optimal air-fuel mixture for complete combustion and efficient energy production. By understanding the stoichiometric ratio for different fuels, engineers can design engines that are more efficient and produce fewer emissions.
