Engineering · Diesel — Performance
Steadily rising exhaust temperatures across ALL cylinders at the same load usually points to:
- AA single failed injector
- BFouled air coolers/turbocharger or general loss of breathing/cooling✓ Correct
- COne cracked liner
- DA loose foundation bolt
Explanation
A uniform rise affecting every cylinder points to a common cause — restricted air supply (fouled filters/cooler/turbocharger) or degraded cooling — rather than a single-cylinder fault.
