The port and helix type high pressure fuel pump, is the most commonly used pump for combustion ignition engines. This pump is more or less similar to the radial piston pump except instead of piston it uses plunger without sealings. As, the plunger moves backward the fuel gets sucked and the forward motion of plunger delivers the fuel at very high pressure. It consists of combination of upper and lower helixes which help the plunger to get the forward motion, the backward motion is provided by the spring mounted at the top dead center of the plunger. The amount of fuel is metered by the rack and pinion arrangement, that rotates the plunger and increase or decrease the suction volume of fuel according to the need. Instead of valves, this type of fuel pump uses inlet outlet ports which are on the opposite side walls of the pump cylinder.

What is a plunger type fuel pump?

The plunger type fuel pump is also a positive displacement pump which sucks and delivers the fuel by the help of reciprocating motion of the plunger. The plunger is enclosed inside a cylinder and one side of the plunger is connected with a push rod which further connects the camshaft. The valves are mounted on the end of the cylinder.

What happens when a fuel pump expands?

And, as the diaphragm expands, the fuel inside the pump pushed out through the outlet valve.

What happens to the fuel pump during combustion?

Thus, the fuel pump needs to supply the fuel to the combustion chamber at the pressure more than that of combustion chamber and ignition takes place.

How does a fuel pump work in an engine?

In the spark ignition engines, the fuel pump supplies the fuel from the tank to the fuel bowl and from there the carburetor mixes the fuel with air and send it to the combustion chamber of the engine.
