Hi, I got a project and I have no idea what to do...I have to do a diagnostic circuit of a lambda closed loop fuel injection that has the corect fill factor of the signal from the lambda sensor : 40%÷60%.
Under 40%, the engine will work on poor mixture and will set a code of 2 digits(between 40...49)
Over the 60%, the engine will work on rich mixture, and will set another code, different from the first one (still between 40...49).
The signaling of the emergency situation will be done with a signaling lamp with 1 Hz frequency and a 0.5 filling factor.
- I have to use a microcontroller, make a proteus simulation, and solve this using functions in C
Until now, I only understood what closed loop lambda is, found some theories in general and learned that 16 bytes microcontrollers are best for engines applications, but I really don't know how to do the circuit or the code....I don't have any knowledge about power electronics or automotive, just some C/C++ and some basic electronics. Any help is useful. Thank you!
