Which condition occurs in a diesel engine when lubricating oil enters the combustion chamber?

💡 Explanation

Oil entering the combustion chamber leads to the **formation of carbon deposits**, because the oil doesn't fully combust. So residue can accumulate in piston ring grooves; therefore, the piston rings become clogged, rather than enhancing cooling.
