A car engine burns a mixture of petrol and air. Fuel Pump is pumped along a pipe from the tank and mixed with air in the carburetor , from which the engine draws in the mixture. In the fuel injection system, used on some engines, the petrol and air are mixed in the inlet manifold.
A fuel pump is an important component of any combustion automobile engine. It serves as the mechanical part of the car and maintains a firmly balanced flow of fuel from the car’s tank to its engine.
A fuel pump sucks petrol out of the tank through a pipe to the carburetor. The pump may be mechanically worked by an engine or it may be electrified in some instances, it is normally next to or even inside the fuel tank.
For those of you with older vehicles and mechanical fuel pumps, the procedure is a bit different. Your fuel pump in that situation has a pump lever that moves up and down as the camshaft spins. This generates a literal pump that draws fuel through the line by way of suction. It’s an easy system that works directly with the engine rather than with an integrated DC motor.
Two major types of fuel pumps
Mechanical fuel pump. The mechanical fuel pump came before their electrical counterpart and they are also referred as diaphragm pumps.
- A gravity fuel pump is placed on the head of the cylinder or the engine block, and a camshaft controls it by moving the pump’s lever up and down.
- Car engines with carburetor use mechanical fuel pumps to move the fuel from the tank to the fuel owl of the carburetor.
- As the cam shaft clicks the lever, the lever in turn pushes a spring that sets other in motion till the diaphragm is forced down the bowl of the pump, improving the level of fuel in the pump’s fuel bowl.
- There is a check valve at both the outlet and inlet part to ensure that the flow is unidirectional.
Electrical fuel pump. This type of fuel pump is used in modern cars and it was we mostly use at M & H Pumps.
- They use the fuel injection system to spray the fuel directly into the engine instead of allowing it to flow from the carburetor.
- This system is not only fast but also more fuel efficient because the injection system can manage the flow of fuel that goes into the engine. However, this fuel system needs to suck the fuel from the tank at highest pressure.
- The electrical fuel pumps consist of an electric motor connected to pump that supports drawing out the fuel and pump into the engine.
- Having an electrical component close to the combustion engine can be threatening as there’s probability of gas vapours escaping and even the small amount of spark can cause fire.
Both these fuel pumps go through our Depot Maintenance for proper service, so that they function properly.
