What to do when a hot engine is hard to start
|

Although usually engines exposed to cold
weather is the most known problem related to car starting difficulties,
hot engines might bring obstacles as well. Many people realize that the
car do not start as easily as it should when the engine is hot and do
not know what to do about it. In order to be able to overcome this
problem, it is important to start by learning why it happens.
Most of the reasons by which a hot engine would be hard to start are
based on problems related to the fuel. When the engine is too hot, fuel
can't circulate properly due to the way in which vapor obstructs it and
therefore the engine wouldn't start as easily as it should or it
wouldn't start at all.
A car engine would keep on gaining temperature until a while after it
was shut off. During this period of time is when the highest amount of
vapor would be circulating around and therefore that is when the
chances it obstructs the engine are bigger as well. This way, if you
are driving in hot weather and you have just turned off the car in
which you experience start problems, you should wait for a few minutes
until starting it back.
Fuel injected engines do not experience this problem as much as others
do due to the fact that the fuel remains inside the injectors by being
under a very high pressure. This way, fuel injected engines would not
become so easily obtruded by vapors as other engines would and
therefore the car would not have the same problems to start as another
would.
Also, engines might become hard to start while being hot if it
coincides with the season in which refiners change from a fuel blend to
another. Sometimes gasoline refiners change from a higher volatility
fuel to a lower one when summer approaches due to the way in which hot
weather causes fuel to evaporate easier. If refiners change back to a
higher volatility fuel while the engine is still exposed to days of
high temperatures, this could cause the fuel to evaporate too much
creating too much vapor and therefore obtruding the engine.
