Why is the engine shaking and weak?
2 Answers
Engine shaking and weakness are caused by severe carbon deposits inside the engine. If there is excessive carbon buildup in the engine, during a cold start, the fuel injected by the fuel injector will be largely absorbed by the carbon deposits, resulting in insufficient fuel entering the cylinders and causing the engine to shake and feel weak. An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. The engine can refer to both the power generation device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines).
I've been driving for over ten years and often encounter issues like engine shaking and lack of power. This is usually due to problems in the ignition system, such as worn spark plugs or aging ignition coils, which weaken the spark and prevent the engine from running smoothly, causing the entire car to shake. Another common cause is a clogged fuel system, like a fuel pump not delivering fuel properly or a dirty air filter not allowing enough air intake. Once, I replaced the spark plugs myself, and the situation improved. I suggest you first check the condition of the spark plugs; if they're worn out, try replacing them. If the problem persists, it might be a faulty sensor, like a malfunctioning oxygen sensor, causing uneven fuel-air mixture and resulting in shaking and lack of power. Regular maintenance can prevent these issues, such as inspecting the ignition system every 50,000 kilometers to avoid minor problems turning into major repair costs. After all, delaying repairs can lead to more severe engine damage and affect driving safety.
