Report broadcast on TF20's 1h newscast 15 November 2005.
It concerns an R21 diesel station wagon doped with water according to the pantone assembly. Generally speaking, it's a good report. Thank you Kevin (and TF1)! (if you are on this site, come take a look at the forum )
Some remarks of Christophe Martz concerning the comments of this report:
- CO2, value of 0,1% very improbable and undoubtedly distorted by dilution of the exhaust gases by steam or an error in the analysis of the device. Indeed the CO2 can not be measured directly but not deduction of the O2 rate knowing the burnt fuel. In reality, to reach such a value, it would hardly be necessary to consume any more diesel.
- Nox: undoubtedly suitable value. I have never been able to do analyzes on Nox. Water injection is a known anti-Nox process.
- HC: very probably wrong. Value too low at the origin to be correct. The use of an unburnt gasoline analyzer could explain this error. HCs are simply not measured (measurable?) On a diesel engine: this analysis is compensated by a smoke opacity test.
