Abstract:
The project aims to determine the source of undetectable water leakage in the vehicles so that the
consumption can be in the engine or from other sources, by adding chemical elements to the water in
the radiator, detect the presence of compounds the chemical element with exhaust gases, if compounds
are present in the exhaust that’s mean water leakage is caused by the engine or the exhaust, and this
leads to saving time and effort in solving the problem.
In this project, a chemical detection material was chosen to facilitate the detect water leakage. We
also show the effect of the detection material on the engine and its theoretical calculations and work
to discover its existence to determine whether there is a leak in the engine or not and its location.
Where we found that hydroiodic acid is suitable in many ways, including the effect on the engine and
the ease of discovering its compounds.
The results were distributed as follows: In the first case the color of the detector paper changed to
black, this indicates that the combustion is normal and that the leakage in the cooling pipes, and the
second case the color of the detector paper changed to the purple color, which indicates that the
leakage in the combustion chamber and in the third case the detector paper contained Two colors,
black and purple, indicating that the leakage is directly in the exhaust.
