Why Does a Car Have Difficulty Starting in Winter?

[OMadelyn]

Car starting difficulties in winter are caused by: 1. Battery malfunction: Lower temperatures in winter reduce the battery's capacity, leading to insufficient starting voltage after prolonged use; 2. Slower oil flow: Cold weather increases oil viscosity, slowing its flow and increasing engine resistance, making starting harder; 3. Frozen exhaust pipe or excessive valve carbon buildup: Engine combustion produces moisture, which can freeze in certain parts, causing starting issues if not melted in time; 4. Engine failure: Severe engine wear reduces sealing and cylinder pressure, also making starting difficult.
