1) How long of a pulse width is 'normal' on an injector?
2) When (compared to valve timing) is optimum to start the injection?
3) When valve open time is less than pulse width, is this very bad?
A quick bit of math shows that at even a modest 5,000rpm on a 280 degree cam the valve is open for 9.3333ms. This seems like a very short time and when i'm seeing some of these smaller n/a motors running over 10,000rpm I kinda wonder how they manage.
