What are the causes of engine misfire in cars?

[McAnderson]

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.
