It is normal for cars to consume more fuel in winter. This is because the engine block temperature is too low, leading to incomplete gasoline vaporization. The air-fuel mixture contains gasoline particles, making it difficult to form a proper mixture. Not only does this make the engine harder to start, but the unvaporized fuel particles entering the combustion chamber also result in incomplete combustion, increasing fuel consumption. Gasoline is a volatile, flammable liquid hydrocarbon mixture obtained through distillation, cracking, or pyrolysis of petroleum. It is primarily used as fuel for spark-ignited internal combustion engines and mainly consists of organic compounds derived from crude oil distillation and various additives. The octane rating of gasoline measures its resistance to knocking (which can cause engine knocking and reduce the efficiency of reciprocating engines).
