How Do Electronic Fuel Injection Systems Work
The fuel exits the fuel tank via the fuel pump. Then the fuel.

Architecture of Electronic Fuel Injection System Sensors.
How do electronic fuel injection systems work. How Do Fuel Injectors Work. They are found mounted into the engine head. Fuel droplet sizes are smaller for enhanced emissions and this finer atomization enables EGR flow tolerance into.
This is called the pulse width and it is controlled by the ECU. How do electronic fuel injection systems work. The fuel from the fuel tanks is fetched and is transported to the fuel injectors by the fuel lines.
The injectors receive fuel either from fuel lines or. All electronic fuel injection systems work in essentially the same way. The common rail injection is the newest high-pressure direct injection fuel delivery system.
It gives the clear idea about how to work a fuel injection system. The Electronic Control Unit is responsible for the measurement of the sensors and the. But there is quite a system in place for that.
How Does Fuel Injection Work. In these modern systems the fuel injectors are electronically controlled valves that spray an extremely fine mist of fuel into the cylinder intake valves at high pressure. We went over the different types and functions of carburetors in a previous episode.
Therefore the amount of fuel actually delivered by injectors is. Electronic fuel injection EFI It travels through fuel lines towards the engine. Electronic fuel injection allows for extremely precise control over how much fuel is sprayed into the cylinders.
It follows a fairly straightforward process to do so. Fuel injectors mounted in the intake manifold of the engine The injectors are mounted in the intake manifold so that they spray fuel directly at the intake valves. Information about the engines operating state is conveyed to the computer via sensors.
There are two groups in the fuel injection system namely fuel lines group mechanical parts and controller group electronic parts. The pressure helps in atomizing the fuel which allows to sensor the accurately calculate the fuel. The volumetric flowrate allowed by fuel injector nozzles is essentially constant and determined by the pressure of the fuel system itself.
The common rail delivers fuel to the individual injectors via short high-pressure fuel lines. In this manner how do electronic fuel injection systems work. Now were going to dive into electronic fuel injection systems.
Sensors are installed in numerous points of the engine and their function is to send out information to the ECU. The ECU Electronic Control Unit or springs control the fuel injectors which are able to open and close a lot of times in a second. Fuel Injectors FI Solenoid actuators that deliver atomized fuel to cylinders based upon other sensor input mainly MAF or airflow by speed-density method and engine crankshaft position CPS.
An advanced design fuel pump supplies fuel to a common rail that acts as a pressure accumulator. This video is the working principle animation of electronic fuel injection system. The fuel pressure regulator constricts the flow of fuel and only lets a calculated amount through to the injectorsThe fuel injectors themselves open to let the atomized gas directly into the combustion.
To wrap it up in short the fuel is directly injected into the combustion chamber of the engine. Let us learn more about how do fuel injectors work. The computer then compares that data to a stored map of fueling requirements.
Once it finds what it likes it tells the injector to remain open and spraying fuel for a given length of time. An electronic unit injector system is installed directly into a cylinder head over every combustion chamber. How do electronic fuel injection system work A diesel fuel injection system differs from a gas engine in that the diesel fuel gets injected directly into the cylinder.
The systems electronic control unit precisely controls both the rail pressure and the timing and duration of the fuel injection. The Fuel injection unit has an electrical pump which is pressurized so that the fuel can be injected easily and with force to make sure the amount of fuel is accurate. After reaching the fuel injector the fuel is raised to the precise level of pressure to which it is needed to raise with the help of a pressure regulator.
An engine camshaft drives the injector typically through the rocker lever resulting in an efficient mechanical and hydraulic fuel system that can minimize parasitic losses. Fuel injection system is a mechatronic circuits that combine mechanical and electronic circuits to achieve a common goal that is to supply fuel to the intake manifold with ideal volume. It travels through fuel lines towards the engine.
In a gas engine a port injection or a carburetor is used to inject fuel prior to the intake stroke outside the cylinder where the fuel mixes with air before it enters the cylinderThe injector on a diesel engine is its most complex. The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open.
