AI Explanation
The correct answer is C) J. The ignition delay period in a diesel engine cylinder is represented by the region labeled "J" on the indicator diagram illustrated in MO-0033. This period corresponds to the time between the start of fuel injection and the start of combustion, where the fuel is being injected and mixed with the air in the cylinder before igniting. The other options are incorrect because: A) G represents the compression stroke, B) H represents the expansion or power stroke, and D) K represents the exhaust stroke, none of which directly correspond to the ignition delay period.
