Ignition and fuel injection timing
This engine adopted the group injection system that the fuel required for one combustion is injected
twice per one cycle.
Therefore, the injector driving circuits can be integrated to 3 circuits and a simpler electrical struc-
ture is obtained.
Firing order : #1, #2, #3, #4, #5, #6
Injection order: #1 and #4
→
#2 and #5
→
#3 and #6 (group injection)
