Why does the car shake severely when starting in winter?

[LuciaRose]

Winter car shaking when starting is caused by: insufficient combustion of gasoline in the engine, resulting in inadequate power supply, or stuck or clogged fuel injectors. Many cases of engine shaking are due to fuel injector blockage or sticking, which leads to insufficient fuel supply and power loss, thereby causing engine vibration. An engine is a machine that can convert other forms of energy into mechanical energy. It was invented in the UK and can be used both as a power generation device and as a complete machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors.
