What are the symptoms of cylinder scuffing in diesel vehicles?
2 Answers
Common symptoms of cylinder scuffing in diesel engines include decreased RPM, reduced power output, and in severe cases, the engine may stall on its own. Below is expanded information about engine cylinder scuffing: 1. Engine cylinder scuffing: Refers to the appearance of distinct longitudinal mechanical scratches and scoring on the inner walls of the cylinder within the piston ring's operating range. In severe cases, adhesive wear may occur, leading to difficulties in engine starting or spontaneous stalling. 2. Causes of cylinder scuffing: The fundamental cause is the inability to form an oil film between the cylinder walls and the piston rings/piston, resulting in poor lubrication or even dry friction conditions.
Bro, if a diesel engine suffers from cylinder scuffing, the noise is huge! It's like having a broken hammer banging around inside the engine, especially loud during cold starts. The sound may lessen when the engine warms up, but that metallic 'clack-clack' knocking noise remains. The car also becomes noticeably 'weak'—stepping on the gas just makes it roar without moving, and climbing hills feels like an old ox panting. The engine oil takes a hit too—not only does it look dirty, but consumption skyrockets, and the exhaust emits a strong blue smoke smell. The coolant temperature gauge also tends to spike. The most frustrating part is the soaring fuel consumption, which hits the wallet hard. If you suspect cylinder scuffing, don't push it—stop immediately and get a professional mechanic to inspect it. Otherwise, you might end up ruining the entire engine!
