Stoichiometric air-fuel ratio by mass for combustion of petrol is
Answers
Explanation:
around 14.7:1
For a gasoline (petrol) engine, the stoichiometric air-fuel ratio is around 14.7:1. This means that, in order to burn completely 1 kg of fuel, we need 14.7 kg of air. The combustion is possible even is the AFR is different than stoichiometric.
Stoichiometric air-fuel ratio by mass for combustion of petrol is 14.7: 1.
Explanation:
The stoichiometric ratio of the air-fuel ratio by mass for a petrol sample (or gasoline sample) as 14.7: 1.
AIR FUEL RATIO is the ratio of masses of air and fuel which is found particularly in an internal combustion engine.
STOICHIOMETRIC AIR FUEL RATIO is the ratio when the exact amount of any air sample is present in the engine to burn the fuel present completely.
The value of air-fuel is considered to be lower -When more fuel is available than air, then the mixture is called a rich mixture. This mixture will give a lot of power and is good for the engine life but is not economical as a lit fuel will get burned in this process.
The value of air-fuel is considered to be higher-If the ratio is high i.e. more air is available compared to fuel, then the mixture is called a lean mixture. This mixture is economical and will burn less fuel but in turn, they are less efficient and can cause engine wear - tear.
