Engine Control Unit (ECU) for EFI Engine using microcontroller

[hameeds01]

hey

guys i made my own Engine Control Unit (ECU) using PIC microcontroller for EFI Engine which controls the spraying of the Fuel injectors, manages the Ignition System consisting of Electronics Distributor less Ignition System (EDIS). In Pakistan EFI engines get assembled only but the manufacturing or designing ECU is still a novel idea.

have a look at it

This ECU has following features:
1) Adjustable Idling Speed + Idling Speed Regulation.
2) Cold Start feature for better cranking in winters. Just starts in first Attempt.(Batch + Sequencial Injector firing)
3) Fully Controllable Ignition Timing (Advance/Retard) no need for Advancer in case of CNG fuel.
4) Injector Duty Cycle is Programmable (Rich/Lean).
5) Cooling FAN can be set at any Temperature. to run the Engine at Optimum Temperature for maximum performance.
6) Fuel Pump runs only if Engine is running.
7) One can tune it for High Performance Vehciles to extract maximum output from the Engine.
8) It can be set on Economical Mode for Extra Fuel Saving.
9) Engine Maximum RPM can be limited at any set point. To enhance the Engine Life.
10) Injectors can be disabled just by giving one Pulse so there’s no need of Emulator for CNG.

ECU Inputs:
Intake Air Temperature Sensor, Throttle Position Sensor, Manifold Absolute Pressure Sensor, O2 Sensor, Oil Pressure Sensor, Knocking Sensor, Coolant Temperature Sensor, CAM position Sensor, Crank Angle Sensor.

ECU Outputs:
3-Fuel Injectors, 3-Ignition Coils, Idling Air Control Valve, VVT Solenoid, Purge Valve, Radiator cooling FAN, Fuel Pump, + RS232 port for Data Monitoring

That's all very nice, thank you for sharing.

Do you have a question, comment or anything else to contribute?

[Mbirt]

Cool! You should share it with your FSAE peers in the region who might be having trouble importing programmable EFI systems.

i am a poor jobless fellow from Pakistan & i made this Engine Control Unit (ECU) with the hope that maybe someone out there will watch it & offer me a job but now it looks like a Dream only.

if anyone is interested in making such a low cost ECU for FSAE using Basic cheap PIC microcontroller then i would love to help/share what i have with me.

Asad,

Well done!

To fulfil your dream you might try finding another "poor jobless fellow" who is good at marketing and sales to be your partner (good engineers aren't always good at these other business issues).

Then start very small with minimal overheads. Sell mainly locally, perhaps to Pakistani student teams, until you develop a good "track record". After that, who knows...?

Sir
ur idea is brilliant but the problem is that here in our country no one knows what ECU thingy is + they r not willing to spend any extra penny on it, all of them r happy with old carburetor stuff, i am not only in ECU stuff but i also design Industrial Automation Control Systems, Motor Drives, 3-phase Inverters etc . . .

Asad,

That is why you need a partner who is good at marketing. Let him educate your potential customers. It takes time. Baby steps first...

Asad,

I did something very similar myself a few years ago, it is certainly fun, and very instructive.

The actual engine management part of it is only half of what you need for a successful product. The other half is the graphical user interface software that the "user" needs to tune and adjust settings.

I quickly discovered that the software in the GUI is going to be huge, compared to the software in the actual ECU.

The GUI is what the customer sees, and how nice it looks, and how easy it is to use will be a very major part of the appeal of your product.

Go to it Asad, many large multinational corporations started out with one really smart guy working out of his garage or bedroom.

And I agree that being able to do the technical stuff will only get you so far. At some stage you will need help from someone with excellent marketing and business skills.

@ Warpspeed Sir i agree with u
