BMW reveals M4 safety car with innovating water injection system

Citat:
The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better.

The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent.

TO je pa že zelo satra ideja ... V nekaterih ICE so to uporabljali olala časa nazaj ...

To ma moj zlahtnik ze par let, samogradanja v tem stilu, sicer se nisem poglabljal, pravi da mu avto manj pije..očitno bo nekaj na tem. Vem da gre za ohlajanje zgorevalenga prostora, ampak raja misli da se vozi na vodo.

ma to je mel Messerschmidt ME-109 leta 1944 da je povečal moč 1800 na 2000 PS
http://en.wikipedia.org/wiki/MW_50

smo pa to veliko vgrajevali v SLO tunane avte, kjer pride do močnega klenkanja zaradi obilice goriva in visokih temp.

poceni sistemi gledajo tlak v turbopolnjenm avtu, kvalitetnejši pa so vzporedno vezani na enega od injektorjev, ki kontrolira vbrizg metanola/vode

CMU team finds regional temperature differences have significant impact on EV efficiency, range and emissions

Citat:
In a new paper accepted for publication in the ACS journal Environmental Science & Technology, Tugce Yuksel and Jeremy Michalek at Carnegie Mellon University have now characterized the effect of regional temperature differences on EV efficiency, range, and use-phase CO2 emissions in the US, based on aggregated real-world fleet data for the Nissan LEAF. Among their findings is that the resulting regional differences in efficiency, range and emissions are large enough to affect adoption patterns and the energy and environmental implications of battery EVs relative to alternatives.

No ja, v resnici bodo v prodaji, ko bodo subvencije. So na tiskovki jasno povedali.

S temi subvencijami je kr neki, zdaj vsi čakajo subvencije,tudi tisti ki bi že februarja kupili,
pol enkrat julija ni več subvencij, tisti ki se septembra odloči za nakup,
potem počaka na naslednje leto.

Če bi bile subvencije od 1.januarja bi sedaj že vozilo novih 20 do 50 EV.

Ne, eGolf in i3 ...
Smo pretekle dni nekaj delali z njima (vsakim posebej), pa sva s sodelavcem zvečer našla čas, da malo neposredno primerjava.
