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

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

Modern high-output turbocharged four-stroke diesel generators utilize pulse or constant-pressure turbocharging where high turbine energy extraction drops exhaust pressure below the intake manifold pressure at full load, optimizing volumetric efficiency and scavenging performance.
