    A car engine burns a mixture of petrol and air. Petrol is

    pumped along a pipe from the tank and mixed with air in the

    carburettor , from which the engine sucks in the mixture.
    In the fuel-injection system, used on some engines, the petrol

    and air are mixed in the inlet manifold .
    A [url=https://hengxing-fuelpump.com/]fuel pump[/url] draws

    petrol out of the tank through a pipe to the carburettor .

    The pump may be mechanical worked by the engine - or it may be

    electric, in which case it is usually next to or even inside the

    fuel tank .

    Keeping the petrol tank safe
    For safety, the petrol tank is placed at the opposite end of the

    car from the engine.

    Inside the tank, a float works an electrical sender unit that

    transmits current to the fuel gauge, signalling how much petrol

    is in the tank.

    The tank has an air vent - usually a pipe or a small hole in the

    filler cap to allow air in as the tank empties. Some of the

    latest systems have a carbon filter , so that fuel fumes do not

    escape.


    How a mechanical pump works
    A [url=https://www.hengxing-fuelpump.com/]mechanical fuel pump

    [/url] is driven by the camshaft , or by a special shaft driven

    by the crankshaft . As the shaft turns, a cam passes under a

    pivoted lever and forces it up at one end.


    The other end of the lever, which is linked loosely to a rubber

    diaphragm forming the floor of a chamber in the pump, goes down

    and pulls the diaphragm with it.
    When the lever pulls the diaphragm down, it creates suction that

    draws fuel along the fuel pipe into the pump through a one-way

    valve .
    As the revolving cam turns further, so that it no longer presses

    on the lever, the lever is moved back by a return spring ,

    relaxing its pull on the diaphragm.

    The loosely linked lever does not push the diaphragm up, but

    there is a return spring that pushes against it.
    The diaphragm can move up only by expelling petrol from the

    chamber. The petrol cannot go back through the first one-way

    valve, so it goes out through another one leading to the

    carburettor.
    The carburettor admits petrol only as it needs it, through the

    needle valve in its float chamber.

    How an electric[url=http://www.hengxing-fuelpump.com/car-fuel-

    pump/] car fuel pump[/url] works
    An electric pump has a similar diaphragm-and-valve arrangement,

    but instead of the camshaft, a solenoid (an electromagnetic

    switch ) provides the pull on the diaphragm.

    The solenoid attracts an iron rod that pulls the diaphragm down,

    drawing petrol into the chamber.

    At the end of its travel the iron rod forces apart a set of

    contacts, breaking the current to the electromagnet and relaxing

    the pull on the diaphragm.

    When the diaphragm return spring raises the diaphragm, it also

    pulls the rod away from the contacts; they then close so that

    the solenoid pulls the rod and diaphragm down again.


    Circulating petrol continuously
    Most mechanical and electrical systems pump fuel only when the

    carburettor needs it, such as [url=http://www.hengxing-

    fuelpump.com/motorcycle-fuel-injector/]motorcycle fuel pump

    injector[/url]. An alternative system has a complete circuit of

    pipes, from the tank to the carburettor and back again. The pump

    sends petrol continuously round this circuit, from which the

    carburettor draws petrol as it needs it.


    Filtering petrol and air
    Both petrol and air are filtered before passing into the

    carburettor.


    The petrol filter may be a replaceable paper one inside a

    plastic housing in the fuel line . A pump, like a

    [url=http://www.hengxing-fuelpump.com/motorcycle-fuel-pump/]

    motorcycle fuel pump[/url], may include a wire or plastic gauze

    filter, and sometimes a bowl to catch sediment .

    The air cleaner is a box fitted over the carburettor air intake,

    usually containing a replaceable paper-filter element .
