AI Explanation

The correct answer is D. The afterburning period in a diesel engine cylinder is indicated by the area K on the indicator diagram illustrated in MO-0033. This period represents the continued combustion of the fuel-air mixture after the main injection has ended, resulting in a slow decline in pressure and temperature within the cylinder. The other answer choices are incorrect because: - Areas G, H, and J do not specifically represent the afterburning period on the indicator diagram.
