What Causes the Abnormal Noise in Honda 190?
1 Answers
Honda 190 abnormal noise causes: 1. Engine mount rubber aging or loosening: The engine mount rubber is the rubber block between the engine and the frame, used to reduce vibration during engine operation and secure the engine. Once the engine mount rubber ages or loosens, the engine will shake, causing abnormal noise. 2. Engine misfire noise: Engine misfire mainly refers to one or more cylinders not working properly, usually manifested as: intermittent exhaust gas flow from the car, severe shaking of the exhaust pipe, and clearly audible engine noise. This phenomenon is closely related to ignition coil failure. 3. "Piston slap" noise: Due to poor lubrication conditions, excessive wear of the piston and cylinder wall leads to the clearance fit tolerance between the piston and cylinder wall exceeding the normal range. During engine operation, the piston skirt impacts the cylinder wall, producing a clear "clanking" sound, which is more noticeable at idle or low speeds. 4. Overly rich air-fuel mixture: When the engine's air-fuel mixture is too rich, the symptoms are: difficulty starting the engine, uneven engine operation, black smoke from the exhaust pipe, accompanied by abnormal noise, and sometimes backfiring. 5. Carbon deposits, clogged filter: Engine power decreases, and fuel consumption increases.
