HOW FUEL MOVES THROUGH THE FUEL LINE
Introduction
A car obtains the energy it needs to move from one point to another via the fuel
line. The fuel line is a semi-complex system of ducts and pumps that run the fuel from the fuel
tank where fuel is loaded all the way to the cylinders of the engine where they ignite and release
their stored energy in the form of mechanical energy. It is important for every car user, not just
the mechanic, to understand the motion of fuel and perform simple repair and maintenance tasks
like bleeding (expelling trapped air from the fuel line) for a better driving experience ("Fuel
System | CarParts.com", 2018).
How Fuel Moves Through the Fuel Line
Seen in the annexed diagram shown, the main elements and chronological
pathway of a fuel line is:
•
The fuel tank. This is the introduction reservoir of the fuel; they mostly vary
from car to car, depending on the design and make of the vehicle. The capacity of a fuel tank
varies from anything between 15 liters to 25 liters.
•
The fuel supply line. The fuel in the tank flows by gravity through the fuel
supply line, a duct, to the lift pump.
•
Lift pump. On reaching the lift pump, the fuel is lifted at low pressures by the
lift pump to the filters. The lift pump obtains its power through the rotating action of the main
engine shaft (the crankshaft via the flywheel).
•
The filters. The fuel filters separate solid sediments in the fuel that might have
accumulated in the fuel tank. Filtration is done because impurities hinder the combustibility of
the fuel and the movement of the same, and may cause clogging of the fuel line ("Fuel Line /
Fuel Delivery for Cars, Trucks & SUVs", 2018).

HOW FUEL MOVES THROUGH THE FUEL LINE
•
The injection pump. The injection pump receives the fuel from the filters, still
under the pressure of the lift pump and in turn, forcefully moves this fuel to the individual
injector nozzles at very high pressures ("Fuel Line / Fuel Delivery for Cars, Trucks & SUVs",
2018).
•
Injector nozzles. Injector nozzles are tiny openings leading into the engine
cylinder where the fuel is atomized then sprayed into the cylinder at the correct predetermined
time. Atomization means the fuel is delivered in the form of a mist, at ext...
