Injection angle

Postby Playmo90 » Tue May 12, 2020 10:53 am

Hello,

I have an asking for define the best value of injection angle, when is calculated this angle and fuel time in the cycle ? In the falling teeth after the missing teeth ?
For me is better to start the injection after having defined the fuel time ?

Sorry for my english and i don't know if i was clear ?

Best regards

The best time is determined by spending many hours on a dyno.

Anything else, is just a guess. Generally speaking end injection around the time the intake valve opens....give or take a lot.

If you use the knobs box to adjust the injection angle point even at idle speed you will very quickly find the injection timing the engine likes, the engine will run richer and smoother (lambda off), then advance the injection timing something like 5 to 10 degrees per 1000 rpm and you will not be a million miles off.

I should add that you should only worry about this once your map is 99.9 % right, just don't get hung up on it.

Thanks you for your answer and your help.
In reality my question is the scheduling in the software when is calculed the injection times and angle ?

Thanks you

I know there is a language barrier....but I'm really not understanding what you are asking ?

He may be asking about start or end point for the reference point. ?
I suggest using the end point and just see what the engine likes.

If you're asking when the ECU software calculates the angles, the answer is virtually continuously.
