Which outcome occurs in an air-start system when fuel injector timing drifts in a large marine diesel engine?

A)Increased cylinder head thermal stress
B)Elevated lubricating oil contamination
C)Reduced compression ignition effectiveness
D)Higher turbocharger compressor surging

💡 Explanation

Cylinder head thermal stress increases because unburnt fuel accumulates during mis-timed injections, causing hot spots via afterburn; this is thermal fatigue, rather than just reduced compression because peak pressures are reached earlier, and not turbocharger issues.
