There are different types of fuel pumps for cars, but one thing is certain: if they are not well looked after, regardless of the model, you could end up left stranded or spending a lot more at the workshop. Are we going to prevent this from happening by getting to know this component better? Throughout this text, we will explain what fuel pumps are, the function of this part, the main models, their particularities, signs that something is wrong and much more! What is the fuel pump? Have you ever stopped to think that we almost never — only in some old models, like the Kombi — see the fuel tank close to the engine? But then, how does gasoline, ethanol or even diesel reach the propellant? Thanks to a component called the fuel pump. These pumps are responsible for transferring the fuel from the tank to the injection system or carburetor.
These, in turn, will power the engine for its operation. Usually just one does the job — except in some high-power models, such as competition cars, which may have more units. How does the fuel pump work? Although the function Chinese Singapore Phone Number List is always the same, fuel pumps may work differently depending on the vehicle model. There are basically two types: mechanical and electrical. The latter is the most modern and is present in all current cars, working together with electronic injection . Mechanical pump These fuel pumps are usually equipped with older vehicles , which use a carburetor or mechanical injection pump (in this case, they are only used to remove diesel from the tank). They are very robust and rarely cause any type of problem. Its operation is relatively simple and does not depend on many components. When the engine is turned, a type of lever (connected to the crankshaft, valve control or other moving part) activates a diaphragm or a pair of gears inside the pump, creating suction.
The fuel then enters through a valve, which prevents it from returning to the tank, and exits through another, connected to the supply system. One of the negative points of this system is that it only works when the engine is moving and depends on rotation to generate more suction. To solve this flaw and make the process more precise, electric pumps were developed, which are much better. Electric pump The operation of electric pumps is very similar to mechanical ones, except that they do not depend on the engine turning to start operating and pump fuel from the tank. In these models, what does the driving work is a small electric motor integrated into the component. What is the advantage of this? Electric pumps are able to maintain a much more constant flow of fuel going to the engine, even at lower speeds. Furthermore, control is easier, which allows you to better manage the system and make vehicles more efficient.
