What Causes an Engine to Sound Like a Tractor?

[DiAlivia]

Engine noise resembling a tractor sound can be attributed to the following reasons: excessive carbon buildup in the engine, use of inappropriate or dirty engine oil, use of low-quality oil, increased engine noise during cold starts or in low temperatures, damaged valves, internal engine malfunctions, etc. Here is some relevant information: Preheating Note: During a cold start, the lubricating oil for engine components does not immediately engage in operation. Instead, it requires a preheating period to allow the engine's lubrication system to fully activate and ensure all components are adequately lubricated before driving. This can effectively prevent wear and tear on engine parts. Self-Inspection: All moving parts in a car produce their own unique sounds, and the engine is no exception. When starting in a quiet state, the engine sound is typically deep and rhythmic. If the engine sound becomes sharp or the operation becomes unstable, it may indicate a malfunction, and the vehicle should be promptly taken to a 4S shop for inspection and repair.
