Air fuel ratio
Air fuel ratio is the ratio of the air and fuel present, while in the combustion process in the internal combustion engine
In petrol combustion engine the air fuel ratio would be 14:1 means 14% will be of air and 1% will be of fuel and this type of air fuel mixture is known as stoichiometric air fuel ratio
If the air which is delivered in the cylinder block (chamber) completely burn the fuel then it is known as stoichiometric air fuel ratio
In this 14% will be of air and 1% will of fuel this fuel ratio can only change when the choke circuit is been choked up
Air fuel ratio are of two type: 1.lean and 2. Rich
In lean mixture the air ratio or air content is more than the fuel and in the rich mixture the ratio of the fuel or its content is more than the air

And then it is passed forward toward the outlet valve which are the one way valve
And hence, the lever of the pump is operated with the help of eccentric lobe of the camshaft during the rotation
Therefore, this is the working and the function of the mechanical fuel pump
Electrical fuel pump
The working of the electric fuel pump is mainly based upon the battery because it is an electric motor
Which sucks the fuel from one side and it is passed to the other side as it is work like normal electric motor
As in the normal motor pump in the fuel pump there is one outlet pipe and one inlet pipe and return pipe
As it is separate from the motor and it is given directly to the charcoal canister to the fuel tank
Therefore, in this way the electrical fuel pump work
Purge valve
Purge valve is a component which consist a one kind pipe which is given at the top of the tank
This part is given because whenever the fuel is sucked from the tank at that time it create the vacuums in the tank
So that when the fuel will be suck from the tank at that time there will be no space to relief the air, so there will chances of the burst of the tank therefore, because of it the purge valve is
