What are the causes of engine vibration when stepping on the accelerator?

[DiKira]

Engine vibration when stepping on the accelerator may be caused by faulty spark plugs, abnormal engine oil quality, unbalanced tires, etc. Here is a detailed introduction about car engines: 1. Overview: The car engine is the device that provides power to the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems. 2. Others: Common gasoline and diesel engines are both reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston motion and outputting power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.
