Engine constants

[Dominix]

Hello everybody. I need a little help on the configuration of the standard injection. This problem concerns a 4 stroke engine with 4 cylinders with indirect injection but with 2 injectors for each cylinder (for a total of 8 injectors). So:
1) To set 2 injectors for cylinder I need only to set the number of injectors to 8 and the port injection type to port injection ?
2) If I set 4 squirts / Alternating, this means that each of the 8 injectors spray 2 times in a cycle, right? I.E. injectors of bank 1 spray at 0°, then at 180° spray injectors of bank 2, at 360° again bank 1 and at 540° spray bank 2.
It's right?

The actual injection angle will depend on your tach input method and unless you are using semi-sequential, it is not locked to any particular angle - it will vary on each re-start.

Ok but basically, with an alternating sequence the injections occur for a single injector or for all the injectors on a bank?

Alternating Batch injection will be all injectors on bank 1 then all injectors on bank2 and so on. You were correct before saying there will be a 180 degree separation between events for your given example, but the initial starting crank angles are not set in stone. That's why it is also called Untimed Injection.

Ok thank you very much for yours time.

I still have a doubt regard the first question.
Thinking about a single cylinder, I have 2 injectors powered by a single physical connection current power supply. So, each current supply splits for two injectors.
How I have to configure my engine constants?
- I have to set 8 injectors ?
- I have to set 4 injectors and then divide the "required fuel" by 2 ?

Thank you again for your time.

The two injectors are connected to the same MS injector driver? Then simply add their flow rates together and use that value as a "single large injector" when calculating the "req_fuel" value. Want an example for a single-cylinder? Here is one I am experimenting with:
