What is the power supply system of carburettor engines?This system is designed to store and supply fuel, air filtration, preparation of the fuel-air mixture and feed it into the combustion chamber of the engine.The amount of the mixture depends on the particular mode of operation of the vehicle.In today's article we would like to pay attention to the carburetor car that fuel is always gasoline.
power supply system of carburettor engines consists of the following components:
- fuel tank.
- fuel lines.
- filters for gasoline.
- air filters.
- carburetor.
fuel tank is a metal container volume.As a rule, cars are equipped with fuel tanks at 40-60 liters.This device is installed in the rear of the car, and he leaves an opening for filling and submission of gasoline fuel lines.The liquid is poured through a special neck.This is a small tube having at the end of the plastic and the metal cover.In some models of fuel tanks it has a special hole for the fuel drain.It is located at the bottom of the container.It designed a hole not to the neighbor it was easier to steal gasoline, but in order to eliminate the accumulated garbage there, the water and sediment.Since the fuel in our gas stations have a "perfect" quality, this cover often involve motorists.
Job supply system of the carburettor engine
Before gasoline goes into the combustion chamber, it goes through several purification steps in the fuel filter.Typically, on modern cars the 1 or 2 of the instrument.Driving the power supply system of the carburettor engine also includes many small details.One of them is a float with a rheostat, which measures the level of fuel remaining in the tank, and outputs the information to the panel.
Once passed the stage of purification of gasoline, he goes further along the fuel line (it is located under the floor) to the pump.This is one of the most important elements, without which the power supply system of carburettor engines would simply not exist.He shakes his gasoline at the fuel line, and when the fuel is mixed with air, ready mix enters the chamber of the engine.The very same pump is mechanically and electronically.But as the carburetor cars appeared much earlier injection, they are established exclusively by mechanical devices.Such a pump consists of the following elements:
- housing.
- intake and exhaust valves.
- strainer.
- with a spring-loaded diaphragm drive mechanism.
Depending on the age and grade of a vehicle fuel pump can be driven by an eccentric which is arranged on the drive shaft of the second pump (oil) or eccentric arranged on the camshaft.In both cases, the detail of rocking lever which acts on the rod.As a result, the power supply system of carburettor engines pumping gasoline fuel lines to the combustion chamber.
