What Causes Engine Shaking and Exhaust Puffing?

[DelFelicity]

The reasons for engine shaking and exhaust puffing include: 1. Engine misfire: The exhaust gas flow shows obvious intermittency, and the exhaust pipe shakes severely, which is largely related to ignition coil failure; 2. Overly rich fuel mixture: Mostly caused by carbon deposits, clogged filters, etc.; 3. Cold start: During a cold start, the engine lubrication effect is relatively poor, and the engine oil has poor fluidity and is more viscous, resulting in abnormal noises from mechanical wear. The car engine is the device that provides power to the car, serving as the heart of the vehicle, determining its power, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.
