Electronic Fuel Injection (EFI) is a substitute for the conventional metering system which mixes the air and fuel in the correct ratio before feeding it down to the main cylinder to power the vehicle.
Usually in a bike a carburetor is responsible for carrying out this task. But, the downside of using a carburetor is that it has fixed settings and it has certain limitations. To overcome this negative aspect of a new system has been introduced. However, for this brand new system to work, it needs data from several sensors. These sensors include an engine speed sensor, temperature sensor, voltage sensor, throttle position sensor, oxygen sensor and an air flow sensor. The data collected from the various sensors are send to the Electronic control unit (ECU). The ECU makes use of the data provided from the sensors to determine the spark advance, the length of spark and other parameters. Then the exact air fuel mixture for that particular instant is fed into the cylinder which in turn delivers optimum power and clean exhaust. All this process is done continuously and happens many times in every second.
A cross section of a fuel injector is shown below:
Typical EFI components:
1) Injectors
2) Electronic control module (ECU)
3) Fuel pressure regulator
4) Fuel pump
5) Wiring harness
6) Sensors
Advantage:
1) Although the electronic fuel injection is much more complicated than a carburetor, it is much more efficient.
2) Fault finding is easy with the right tools
Disadvantage:
1) Higher cost than carburetor.

its a good idea but i am just thinking about the construction and conditions of working but require more info with views.
Good brief and this fill someone in on helped me alot in my college assignement. Thanks you on your information.
this is very interesting concept.Basically my aim is to produce the more effective fuel injectio method.so try to give more information this.
Is it possible to obtained good air fuel mixure ratio: tell me sir! CELL NO. 8983740247
i want to full report on this Electronic fuel injection (EFI) system & i hv trying to my bike
so pls gv me detail with image
i’m doin dis as ma project so plz send me a detailed report on EFI..
plz send me some more information………….
hey your blog design is very nice, neat and fresh and with updated content, make people feel peace and I always like browsing your site.

Your seminar and project topics are amazing. Please I need a detailed diagramatic explanation of the EFI with calculations related to flow and design considerations.
Thanks
yeah my dad will like this
Sorry for my bad english. Thank you so much for your good post. Your post helped me in my college assignment, If you can provide me more details please email me.
this efi good for final year project? i want its cost for doing this is my final year project. please reply me and guide me. thank you.
only because of its cost we can’t ignore its qualities as compared to carburetor. and till the date its one of my favourite project and surely i will make work on it
thanks for this help
Give me more sketch
pls send me the details of this project.also give the clear diagrammatic explanation.
I want to change carberator to EFI in my bike.what i want to do. . . Pls send full detail and workings &block diagrams etc. . .
Thanku and so i need the information about the EFI including all requirement plzz….!
it is so good for my final year project…plz give me some more details..
It’s good and enhancing my knowledge more..
can u give some more details for further…..
thank u so much..
keep it up..
Great and very interesting post.. Excellent for my final year project, please give more details sir..
Thank you so much..
plz snt ful info.abt EFI. b’coz am doing tis as my project.plz help me th pics nd working
vry interesting project. bt hw much wud ths kind of project cost.
I have a project for final year of mechanical engineering students.
Interested may contact.
The title of project is “Gear cutting Attachment on Lathe”.
Its a special Fixture which when attached on a lathe m/c can be used to cut profiles of gear.
Thus we do not need milling machine for that.
This is locate in PUNE.
Contact 9021658656
its so good but i need more information about this
i would like to do a project on efi in two wheelers…will u pls send me the cost estimation of this project and will it be more efficient then using carburator.
sir, i have selected this as my final year project title.it is my request from you to please send me the necessary details regarding this.
Please I need a detailes of the EFI with diagram also give calculations related to it
I LIKE THIS TOPIC. PLEASE GIVE FIGURES RELATED THIS.
its nice i need complete inf regarding it , iam dng it has a project , so giv me d inf as soon as possible…….
please I always wanted to make it as a final year project but i don’t know the procedure to make it. Please send me the procedure how to create an electronic fuel injection project . It will be a great help.
Reply as soon as possible Its urgent
Thanks in advance

Avik
this is very good idea and it helps me more.so thank you.
This is a wonderfull idea… i need full information about dis topic for my final year project…. so thank uuuuuuu
SIR, THE THEME U HAVE MENTIONED THAT’S VERY GOOD.IS SUCH SYSTEM IS USING THESE DAYS………PLZ REPLY SOON……..
It is v.good topic. but,want to more information…………….
Hi,i have do this project. Give more information. Thank you sir…..
Hi, how do this project,give that more detail…. Thank you
nice
i need a complete writeup,diagrams and calculations of EFI for my final year project
