Q: Diesel ignition delay terminology: identify the correct name for the interval between injection and ignition. Definition prompt: In a CI (diesel) engine, the time between start of injection and actual start of combustion is called what?

Concept/Approach After fuel injection begins, atomization, vaporization, and mixing with hot compressed air take finite time before auto-ignition occurs. This interval is the ignition delay period. Final Answer Delay period.

Difficulty: Easy

Pre-ignition period
Delay period
Period of ignition
Burning period

Correct Answer: Delay period

Explanation:

Concept/Approach
After fuel injection begins, atomization, vaporization, and mixing with hot compressed air take finite time before auto-ignition occurs. This interval is the ignition delay period.

Final Answer
Delay period.

Effect of compression ratio on knock in petrol (SI) engines: evaluate the statement. Statement: “Detonating (knocking) tendency in petrol engines increases as compression ratio increases.” Choose whether the statement is correct.
Nuclear marine/space propulsion: fuel form for compact propulsion reactors Reactors designed for propulsion applications (e.g., naval or space power units) require which fuel form to achieve a compact, long-life core at practical power density? Choose the correct option.
Diesel engines on weak (lean) mixtures: effect on thermal efficiency For compression-ignition (diesel) engines operating with weak or lean mixtures (excess air), how does the thermal efficiency change? Choose the correct option.
Diesel ignition principle: fuel spray ignition due to hot compressed air Statement: In a diesel (compression-ignition) engine, fuel is injected as a fine spray into the cylinder and it ignites because the compressed air temperature is high. Decide whether the statement is correct.
