Hi Guys,
Could someone tells me what is the unit of the InjPulseWidth when log is made with Evoscan please?
Example:
InjPulseWidth
2.304
2.304
0.768
1.28
1.28
1.024
2.56
5.376
I was thinking it was milisecond but making numbers, it sounds bizzare to me since if you are @ 7500 RPM, frequency is 125Hz and then max inj Pulse is 8ms...
Any help?
Thanx a lot.

 

milliseconds

7500 RPM isn't how many times the injectors fire - Don't forget its 2 stroke for 1 crank and then there is only 1 power stroke every 2 cranks..

im pretty sure thats right..

 

I thought one injector did it's duty in miliseconds every rotation in a 3 - 4 - 2 - 1 note.

 

Thanx Tephra!
You 're absolutly right, bad math again!!!
That perfectly explains why bigger injectors are needed for bigger boost.
Is someone knows what is the gas regulated pressure on the injectors ramps?
Cheers.

 

I read that:
Standard value: Approximately 230 kPa (33 psi) at curb idle
Someone can confirm?
Thank you all.

 

MOst fuel injection systems operate at 43.5psi and if it is turbo it has a 1:1 rising rate. So if the base pressure is 43.5psi and you are boosting 10 psi the fuel pressure increases to 53.5psi.
I dont know if this answered your question or not, but I tried.

 

Yes it answer my question!!!!
Thank you very much, I was thinking ECU was modulating injection pulse depending on boost, so this is a great help...
My plan is to develop my own water injection system but I still investigating...
I will share my works once something done.
Thanx again.
