What are the causes of engine misfire in cars?
2 Answers
Car engine misfire can be caused by: 1. Excessive wear gap in engine cylinder liner piston rings; 2. Fuel injector wear; 3. Spark plug carbon buildup. Engine misfire refers to insufficient power caused by engine failure, resulting in lack of power, with situations where a minority of cylinders are not working. Engine misfire can shorten the service life of lubricating oil and may lead to sudden engine stall, increased fuel consumption, and black smoke emissions. An engine is a machine capable of converting other forms of energy into mechanical energy, originating in the UK. It can refer to either power generation devices or the entire machine including power units, with types including internal combustion engines, external combustion engines, electric motors, etc.
A few days ago, my car was shaking badly, and the engine sounded like a tractor. The mechanic later told me it was misfiring. There are many possible causes: old spark plugs or severe carbon buildup can directly affect a cylinder's ignition efficiency; aging or cracked ignition coils can also prevent proper firing; clogged fuel injectors or a short circuit in the fuel line can stop fuel from entering the cylinder, causing issues; a faulty compression system, such as poorly sealing valves or worn piston rings, can lead to insufficient compression pressure, extinguishing the flame; and a faulty crankshaft position sensor or oxygen sensor can send incorrect signals to the computer, causing misdirection. If these problems aren't fixed early, the car will jerk while driving, fuel consumption will skyrocket, and the engine core may be damaged. I've since developed a habit of regularly checking these components, which has saved me a lot of hassle.
