What are the causes of engine vibration?
2 Answers
Engine vibration can be caused by: 1. Damaged spark plugs, where the wear of the spark plug electrode gap leads to insufficient spark ignition, resulting in incomplete combustion of the air-fuel mixture; 2. Poor quality gasoline, which affects the atomization effect of the fuel injector, leading to incomplete combustion of the mixture in the cylinder; 3. Dirty throttle body or excessive carbon buildup in the fuel injector; 4. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor. An engine is a machine that converts other forms of energy into mechanical energy, first developed in the UK. It can refer to either the power generation device or the entire machine including the power unit. Types of engines include internal combustion engines, external combustion engines, and electric motors. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to generate power.
I've been driving for over a decade, and recently the engine keeps shaking, feeling like the whole car is shivering. It's really annoying. This kind of vibration usually has several common causes. First, there could be an issue with the ignition system—spark plugs with worn electrodes after prolonged use may not ignite smoothly, or aging ignition coils might deliver unstable current. Then there's the fuel system, such as clogged fuel injectors with carbon deposits causing uneven fuel spray, or too much sediment at the bottom of the fuel tank affecting fuel quality. Mechanical issues are also common, like worn-out engine mount rubber leading to insufficient support, or poor piston ring sealing causing compression ratio imbalance. Excessive carbon buildup can block the intake manifold, leading to uneven airflow and resulting in shaking. It's advisable to listen for any unusual sounds before starting the engine and get it checked by a professional shop as soon as possible. Don't take it lightly—safety comes first.
