Why Does the Honda 190 Engine Make Abnormal Noises?

[Jan]

Honda 190 engine abnormal noises are caused by the following reasons: Engine Mount Rubber Aging or Loosening: The engine mount rubber is the rubber block placed between the engine and the vehicle frame. Its function is to reduce the vibration and buffering caused by the engine's operation and to secure the engine in place. Once these engine mount rubbers age or loosen, the engine will start to shake, resulting in abnormal noises. Engine Misfire Abnormal Noise: Engine misfire mainly refers to one or more cylinders of the engine not working properly. It is usually manifested as an obvious intermittent flow of exhaust gas from the vehicle, accompanied by severe shaking of the exhaust pipe, and a clear "popping" or "thumping" sound from the engine. This phenomenon is closely related to ignition coil failure. Overly Rich Air-Fuel Mixture: When the engine's air-fuel mixture is too rich, the symptoms include difficulty starting the engine; after starting, acceleration is difficult, and the engine runs unevenly; the exhaust pipe emits black smoke, accompanied by a "popping" abnormal noise from the engine, sometimes even backfiring; the engine's power decreases, and fuel consumption increases. This is mostly related to carbon buildup, clogged filters, etc.
