Which of the following statements is correct regarding a turbocharged four- stroke/cycle diesel generator?

Correct Answer: Option D — At full load the intake manifold pressure is greater than the exhaust manifold pressure.

At full load, a turbocharged diesel engine requires higher intake manifold pressure than exhaust manifold pressure to establish a positive pressure differential across the cylinders, ensuring effective scavenging, thermal cooling, and optimal volumetric efficiency during the valve overlap period.
