912iSc Cylinder Not firing
We have some doubts regarding the engine start response in the ground test bed. We are using the 912iSc engine. Observations are below:
1. On the first-day crank, we have cranked well without any issues, other than Lane B was flashing sometimes with Stall sensor fault
2. On the second-day crank we found only 2 cylinders were fired (EGT 2& 4) and RPM was not picked even after we set 60% throttle during the start.
Then our engine maintenance team cleaned the injector and attempted to crank
3. On the third day, again only 2 cylinders were fired, but this time (EGT 2 & 3) and RPM were not picked even after we set 60% throttle during start.
Above observations are monitored in EMU display and logged the data in Sd Card. The data attached for your review and suggestions. Please suggest the way forward to us.
Do ECU lanes not commanding for ignition? we don't have clue. Please help us. We have ECU extraction data also. If required please let me know i am ready to share (.zip) format.
