At a time when many articles about the Pantone process appear in different official media, we would like to remind you of the Chambrin process.
This process was invented by Jean Chambrin in the early 1970, ie during the oil crisis. Mr Chambrin is an engineer and garage mechanic in Rouen. According to the inventor, his method allowed him to consume a water-alcohol mixture with a certain proportion of water (up to 60%).
The principle was similar to that of Pantone since it involves recovering the heat of the exhaust gases (40% of the energy of a heat engine is lost in the exhaust) to "pretreat" the gases of admission.
Anyway, if the first tests were promising, this invention was never put on the market and Chambrin never revealed the "secret" of its "black box" (the heat exchanger).
So myth or reality? These few articles and the reading of the patent will allow you to make your own opinion.
