History of water injection in internal combustion engines

Document presenting the work of water injection on high compression engines by the inventors of the first diesel engines, inventors that we can only admire.

It is undoubtedly the rise in the price of fuels, constant throughout the XXth century, which gave rise to the rumor of the famous "water engine", an invention supposedly deliberately kept secret by the petrochemical industry so as not to not kill the gasoline engine and its lucrative fuel, gasoline or premium fuel. This sea serpent has been circulating since the 1920s, regularly maintained by the press and now by television (and the Internet) whose emissions are of an increasingly dismaying scientific and technical level ...

Comments and analyzes

Here are the remarks Christophe Martz could make about this document and following his own experiences:

  • page 3) at the top right, we are talking about 30 to 35% savings with water injection.Results found by the water doping arrangements.
  • page 3) bottom right: the document talks about OPECHowever, OPEC did not exist at the beginning of the XXth century. It was created in 1960 and became important after 1973… It is therefore a historical error.
  • 5 page) bottom left, yield 20% of 1er petrol engine.It was much less because 20% is what we had in the 80s and 90s and currently ... I would say between 10 and 15% at the time. But in general I find that CS are VERY weak in these tables (they are the same as diesel engines before high pressure injections). Especially since the fuels of the time were not of the same quality as the current ones.
  • page 6) top left: gasifier that breaks down water…By reaction with the hot carbon
  • page 8) middle left: tax on alcohol which is drunk = ethanol The author then speaks of benzol ... nonsense.
  • page 9) bottom left: 250 g / cv.h of white shale…What is the calorific value of the blank slate? In order to compare with the current specific consumption
  • page 11) legend picture left. I quote: "with GO, power
  • 14 hp and output 0.23. with GO-water, power 23 hp and 0.60 output or a CS of 225 GB and 22 grams (of what? water?) per hp. »Inconsistent figures because 225 grams do not give a yield of 60% or the PCI of the GO of the time was much lower (divided by 2 approximately therefore unlikely). The conversion cs into yield is quite simple knowing that a liter of GO = 9.8 kwh / l, from which 225 g / cv.h give a yield of 0.28. We are far from 60%…
  • 12 page) top left water = improving flexibility so relaxing, less jarringFacts found on all current doping edit without exception.
  • 12 page) top doite, metal water decomposition red hotSee metal fire and Lavoisier experience.
  • page 12) bottom right, 3x diesel power per oxygen of water at equal consumption!Unbelievable figure… because far too important (we would reach a yield close to 100%)
  • page 14) top left, "hydrogenation of hydrocarbons due to the presence of cracked water by copper and nickel pipes at 250-300 ° C" very interesting point because copper (pipes) and nickel (stainless steel) are present in the assemblies in doping.
