Working Principle of fuel pumps:

A fuel pump is a fluid handling device

that moves gasoline from the fuel tank

to the engine. It’s often found in internal

combustion engines. The fuel pump in

spark-ignition engines transports gasoline

from the tank to the fuel bowl, where the 

carburetor mixes the fuel with air and

transports it to the engine’s combustion

chamber. In combustion ignition engines, 

the fuel pump delivers high-pressure fuel

straight to the combustion chamber. In

combustion ignition engines, the combustion

enclosure is already filled with highly 

compressed air at the moment of combustion.

As a result, the fuel pump must deliver fuel

to the combustion chamber at a pressure

greater than that of the combustion

chamber, and ignition occurs.

Types of Fuel Pump: 

1.Mechanical  fuel pump

These are mostly low-pressure fuel pumps,

however they are occasionally employed for

high-pressure applications whose primary

function is to move gasoline from the tank to

the spark-ignition engine’s fuel bowl. There are

two types of mechanical fuel pumps:

diaphragm-type fuel pumps and plunger-type

fuel pumps

2.Electric fuel pump

These pumps are commonly found in fuel injection

systems.This tremendous pressure might cause the

gasoline within the pump to ignite, resulting in an

explosion. As a result, the electric fuel pump should

be maintained away from the engine.

3.High-pressure fuel pump

These pumps are often employed in combustion

ignition engines for the direct injection of fuel into

the combustion chamber. Pumps of this sort operate

at pressures of more than 200 Pascals. These pump

systems are particularly complicated and durable to

manage such high pressure. The basic high-pressure

pump system, which includes flow rails, metering

units, and distribution units, aids the pump in

delivering fuel to the combustion chamber without

wasting or over fueling it.
