Injectors
•
“Injectors warming up”
-in parameter
“Injectors warming up time [s]”
we can set period of
time for which the gas injectors coils should be preheated by single pulses from ECU
(properly shortened so they won't cause opening of injector) before first changeover to gas.
F unction is being applied only if the reducer temperature is not higher than “ Hot engine
temp”.The length of pulse is being set automatically depending on the type of selected
injector from injection rail in Gas Panel.
•
“Minimum gas injector opening time [ms]” -
this parameter makes possible to force the gas
injectors to not try to open for time period shorter than that time value. If calculated
injection opening time would be shorter than this value, the injector will stay opened for that
amount of time instead.
That feature might be useful when calculated gas injection opening time is lower than real
minimum value of opening time for particular injectors -which may cause engine stalling
(in example: during exit from cut-off).
Eg. when we set this parameter at 3,3 ms and the controller has calculated gas injector
opening time less than 3,3 ms (like 2,6 ms) injector will be forced to be opened for time not
shorter than 3,3 ms.
Attention:
For VALTEK 30/RAIL IG1 type injectors the parameter value shouldn't be
higher than 3,8 [s].
