* Reduced fuel vaporization. When the engine is cold, the fuel is less likely to vaporize, which means that there is more liquid fuel available to mix with the air and create a combustible mixture. This makes it easier for the engine to start.
* Increased air density. Cold air is denser than warm air, which means that there is more oxygen available to mix with the fuel. This also makes it easier for the engine to start.
* Reduced wear and tear. When the engine is cold, the metal components are less likely to expand and contract, which reduces wear and tear on the engine. This can make it easier for the engine to start.
* Better battery performance. Cold weather can actually improve the performance of a car battery, which can make it easier for the engine to start.
Of course, there are also some reasons why an engine might start better when it's warm. For example, the oil is thinner when the engine is warm, which can make it easier for the engine to turn over. Additionally, the engine might be more likely to start when it's warm if there is a problem with the fuel system or the ignition system.
Overall, there are a number of factors that can affect how well an engine starts, and it's not always clear whether an engine will start better when it's cold or when it's warm. However, by understanding the factors that can affect engine starting, you can increase the chances of your engine starting successfully.
