Fuel Injection means the supply of fuel in the combustion chamber of an internal combustion engine.
The injection of fuel is done by a part named Injector.
In a petrol engine, fuel injection is carried out by a carburetor.
Fuel injection atomizes the fuel through a small nozzle under high pressure.
Carburetor relies on suction created by intake air accelerated through a venturi tube to draw the fuel into the mainstream.
There is various fuel injection system used in automobile engineering. Here you find all of them.
This is an old method that is obsolete nowadays. In this method, Air is compressed at very high pressure by means of an Air Compressor.
A blast of this Air is then injected carrying the Fuel along with it into the Cylinder.
Due to the varying Pressure of Injection Air the rate at which the fuel is admitted can be effectively controlled.
The combustion takes place nearly at Constant Pressure.
Due to High-Pressure, the Air Compressor weight increases and the net output of the Engine is decreasing.
This is an Airless Injection System. Hence the fuel under Pressure is directly injected into the combustion chamber in an Atomized State.
This is useful for small and also for big Diesel Engines.
It requires a pump to deliver the fuel at High Pressure.
This Fuel Injection System is further divided into two systems.
In this system, each cylinder has its own individual high-pressure pump and a metering unit also.
This is a quite compact system.
It has a higher manufacturing cost due to the close tolerance required at production.
The Fuel is pumped by a Multi-Cylinder Pump into a common rail, the pressure in which is controlled by a Relief Valve.
01) Simple in construction
02) Lighter in weight
03) Lower Fuel consumption
04) Lower initial cost
05) No High-Pressure Air compressor required to start the Engine
