Let’s look at some of the engine parameters first. In the following screens try to spot abnormalities in mechanical, scavenging and fuel oil systems.

Conclusion:

• Pcom is the same, no problem in liner, piston ring mechanical condition.
• Peak pressure is lower.
• Maximum injecion pressure (PINJM) is lower than normal, indicating probelm in fuel injection system.
• Fuel pump performance is normal, timing is normal
• From above analysis it can be concluded that fuel injector leaking.
