It's not necessary if you have fuel injection. Any gas engine which does not have fuel injection, like most small equipment engines, uses a carburetor. The carburetor releases the fuel as a mist into air being drawn into the engine. That gets fuel and oxygen into the combustion chamber in a highly combustible condition.
The air fuel ratio of the petrol engine is controlled by Carburetor
Pressure Die Casting
It is necessary because if the engine is still on, it will use up the petrol you are filling up.
The carburetor is normally found just above the engine, it controls the petrol and air mix prior to combustion. Fuel injected and diesel engines do not need a carburetor.
if your car is petrol and using a carburetor...means maybe the auto choke let in too much fuel into the engine....
not enough octane in your petrol. To stop the run on, turn your engine off while it is in Drive. Then switch to Park
Either a carburetor or a fuel injector.
Used prior to the introduction of fuel injection to mix the fuel & air at the proper mix for an internal combustion engine.
unless its a diesel, yes
There is no difference. Petrol is just another name for gasoline. MPFI just means Multi-Point Fuel Injection. A petrol (gasoline) engine can be MPFI or it can have a carburetor. It can have many different ways to get gasoline (petrol) to the cylinders.
YES AND NO AS WELL The main disadvantage of carburetor is vapur lock in hot ambient temperatures petrol do form the homgeneous mixture with air but not always some tiems it goes in form of liqid also in cylinder the systems like mpfi replaced the carburetor and they inject the liquid petrol inside the cylinder
The traditional such device for a gasoline engine is a carburetor, but modern engines can also use injection nozzles; these are standard for diesel engines.
