Which limitation arises when operating a diesel engine at extremely low load conditions?

💡 Explanation

When a diesel engine runs at very low load, the compression temperature drops because less fuel is injected per cycle reducing peak temperature rise. This reduces combustion efficiency due to slower kinetics, causing incomplete combustion that leads to increased engine emissions. Therefore incomplete combustion occurs, rather than detonation or lubricant issues which occur at high loads.
