What condition causes high exhaust gas temperature across all cylinders of a diesel engine?
Direct Answer
Option B: Engine overload, fouled turbocharger compressor/turbine, or restricted air intake filter
Global exhaust temperature spikes across all cylinders indicate restricted airflow or excessive thermal loading. Fouled turbocharger compressor wheels, clogged air filters, or high engine power outputs impair scavenging and combustion efficiency, resulting in elevated exhaust energy.
