The engine's hotness or coldness can both contribute to the difficulty when starting the engine. Some drivers know that their cars do not start as snug as it should when the engine is hot or cold. Among these drivers, only very few know what to do.
In order to surpass this problem and to prevent it as much as possible, learn how to solve it by knowing why it happens.
Difficulty in Starting a Car Engine
1) What to do when a hot engine is hard to start?
- Most of the causes are fuel related problems.
Fuel cannot circulate well due to the way in which vapor blocks it. As a result, the engine would not start as easily as it should. In worse cases, it would not start at all. This happens if the engine is extremely hot.
Even after the engine is shut off, it would keep on acquiring temperature for a short while. The biggest amount of water vapor would be spreading around during this process. It therefore means that during this period, there are higher chances of its obstruction to the engine.
So when you are driving in hot weather and you have just turned off the car and you experience difficulty in starting the engine, do not panic. Just wait for a couple of minutes and before starting again.
- The coinciding of the engine's hot temperature to a hot weather outside.
In this scenario, refiners alter from a fuel blend to another. Due to the process where in hot weather causes fuel to evaporate faster, gasoline refiners sometimes alter from a higher hot blooded fuel to a lower one when summer approaches.
The fuel could evaporate too much that it would create too much vapor and would eventually inflict the engine. This instance happens when refiners alter back to a higher hot blooded fuel while the engine is still exposed to high temperatures of the summer season.
Fuel Injected Engines
Because the fuel remains inside the injectors by being under a very intense pressure, engines that are fuel injected do not experience and suffer this problem as much as others do. Fuel injected engines would not become so easily moved by vapors as compared to other engines. From this fact, it can be further deduced that auto mobiles may have different problems in starting their engines.
2) Why a cold engine is hard to start?
Difficulty in starting a cold engine is really a problem especially to those living in cold areas. This is experienced due to several reasons,
- The cold effect on liquids evaporation.
Less gasoline is evaporated when the engine is cold. This causes the fuel to be more burdensome to burn due to the fact that it is burnt when it is evaporated.
- Oil becomes much thicker in cold areas
This is another reason why cold engines are hard to start. Like any other fluids, oil alters its characteristics when it is heated or when it is in a very hot weather. Often times, this causes the oil to have problems at the time it circulates in the engine of the vehicle.
- Batteries loosestheir agility in cold weather
Under a cold weather, the car batteries sometimes experience problems that consequently affect the engine of the car. When being cold, batteries loose their agility. This is because they do their jobs due to chemical reactions. And when they loose their agility, of course it means that they do not function well. Under these circumstances, the energy of the car is affected and so the engine start is also affected.
- Air intake
Like in the case of your Dodge car, the Dodge cold air intake, it might not be functioning well that affects the performance of your engine.
What to do to start a cold engine
If these problems happen together at the same time, they imply a huge problem in starting the engine. To solve this,
- Spraying Ether into the engine will start the car
Use one that would evaporate quickly and help the engine start. Do this to overcome the problem on the lack of gasoline evaporation.
- Use thin synthetic oils
Since thick engine oil will not circulate well during cold weather. Find ways to isolated your from the coldness outside.
