We are glad to send you the 20th INFO MANEJO's issue. Today we offer you to learn why sleeping well is related to intelligent driving and which are the causes of the different exhaust gases colouration.

We also invite you to visit our new web site where you will find previous INFO MANEJO issues, in their Spanish and English versions.

Manejo
   Sleeping well, better driving
There is a close relationship between beliefs and behaviour. Any belief can determine a type of behaviour related to that belief. We must pay attention to our thoughts, they influence our way of driving. Modifying our beliefs system implies anticipating behaviours which are non beneficial for driving.

A popular belief is to think that though we had not rested or slept well, we can drive a vehicle normally. These mistaken beliefs about sleeping and driving come from the argument people give, consisting of reacting when they are falling asleep. Nevertheless, feeling sleepy is not a voluntary action and when a person is very tired or if he hadn't slept for a long time, he can fall asleep anyplace without noticing it. When we drive and we are sleepy, the chances of an accident to happen are much bigger.

Besides, driving a vehicle feeling sleepy slows down our reaction time. The following example of an alert driver and a sleepy driver illustrates this.


Also, some persons believe that sleeping for a long time before driving; would prevent them from having to rest later. This is incorrect. Sleeping is not like money. It can not be saved for future times and then ask for loans to use it when necessary. Nevertheless, sleep functions like money because we can go into debt if we do not sleep enough and then we owe ourselves more sleeping hours.

It's important to stress the fact that drowsiness can not be solved with concentration, self control or drinking coffee. Caffeine is a powerful stimulant, but not a sleeping substitute. If we drive without sleeping and we drink coffee or another stimulant, micro naps might happen: the person falls asleep for 4 or 5 seconds, being this a serious risk when driving.

That's why knowing which are the mistaken beliefs we can drive safely and intelligently.

    Exhaust fumes colour diagnosis
For heavy and light vehicles with four cycle internal combustion engines, petrol or diesel, it's recommended to check the exhaust gases colour; they can be a flaw indicator. When they are not almost colourless, we should pay attention and bear in mind the different causes that may be producing this colour change. Some examples that help to identify these causes:

White smoke:

This kind of gas is water vapour and is normal if the engine is cold. However, if the engine is hot and the gases are still white, this might be indicating some flaw in the head gasket -cylinder gasket-. This might be related to the refrigerant liquid decreasing, thus, we should check its level periodically.

Blue smoke:

When the lubricating oil usage is excessive, the exhaust gases will be coloured blue. This might indicate that the lubricant is reaching the combustion chamber, possibly because:

+ the segments -rings- are stuck, broken or worn out.

+ some valve guides do not seal correctly or are deteriorated.

Black smoke:

Black exhaust gases usually appear when there is an incomplete combustion or because the fuel is consumed excessively. The feeding system -injection or carburet- and the fuel and air filters must be checked.

All in all, right away we see the exhaust gases coloured, we must check the vehicle in case any of these mentioned flaws exist and need the specialists' attention.
