Many of us are familiar with "accelerator pedal",but it has an alternative name called "Throttle".
The function of this throttle valve is to increase the power of the engine by allowing maximum air/fuel mixture for combustion.
The throttle section consists of a butterfly valve and pump cams.The pump cams is connected to the throttle lever and it is controlled by the throttle pedal. The pump cam consists of two or three holes in it and is bolted to the throttle lever. The holes in the pump cams are numbered with 1,2,3.They are the easily replaceable parts of an engine throttle system.
When the accelerator pedal/throttle pedal is pressed the fuel is passed from the fuel tank and it mixes with air in the carburetor.Once the air+fuel mixture is combined they pass near the butterfly valve.
The butterfly valve is controlled by the pump cams by means of throttle lever,when throttle is pressed the butterfly valve opens and allows the air+fuel mixture in to the engine cylinder for combustion.Similarly when the throttle pedal is released ,the butterfly valve closes blocking the air+fuel mixture to the engine cylinder.Like wise according to the throttle pedal movement the butterfly valve acts,and according to the butterfly valve movement the engine delivers its power.
Even when the throttle is completely stopped,there will be a minimum amount of air+fuel mixture which prevent the engine from kill.
