Starting a car with a cold engine can be very difficult sometimes and it can become a real obstacle for those who live surrounded by extremely cold weathers. This way, for all those who might experience this problem it is not only important to learn how to overcome it but also why it happens in order to be able to prevent it as much as possible as well.
Cold engines might experience problems at the time to start due to different reasons. One of these reasons can be based on the effect which cold has on liquids evaporation. When it is cold, gasoline evaporates less and this cause it to be more difficult to burn due to the fact that it is burnt when it is evaporated.
Another reason by which a cold engine might have problems to start is caused by the fact that oil becomes much thicker in cold than the way it is in hot. Oil, like any other liquid changes its consistency when it is exposed to very low temperatures as well as it changes back when it is in a very hot weather, and this might cause oil to have problems at the time of circulating in the car engine.
Besides the engine, car batteries might experience problems while being in cold weathers as well and this could affect the engine. Batteries function through chemical reactions which loose agility while being cold and therefore, in such circumstances, batteries don't function properly. When this happens, the car energy becomes affected and this causes problems for the engine start.
If these three problems happen together, starting an engine might become a really hard task to achieve. In order to overcome the lack of gasoline evaporation problem, you can spray ether into the engine which would evaporate quickly and help the engine start. Besides this, you can also to prevent having oil too thick which wouldn't circulate properly by using thin synthetic oils. You should also try to maintain the car isolated from cold as much as possible, but by using the two last mentioned methods you would experience much less problems at the time of staring the car in cold weather.
