 Posted: Sat Apr 10, 2010 2:33 pm Post subject: New Ethanol adapter from Ukraine |
 |
|
Hello!
In Ukraine more than 2 years ago we started "Bioethanol fuel program", and start to using pure ethanol as fuel, not mixing it with gasoline. besides the environment, pure ethanol is much cheaper than gasoline, and adding 15% of gasonine is considerably raise the price.
for converting usual gasoline automobiles for ethanol fuel was chosen strategy "piggyback device + cold start device".
after some tests we choose startup gasoline tank as "cold start device".
Piggyback device is like other piggyback devices on market, but wit some additional functions and very low price.

It can be installed in 10-15 minutes by every mechanic or by any handy person, no adjusting required.
* Fully digital - microprocessor inside, surface mount technology.
* Cold start function.
* Very simple user interface, Auto and manual modes.
* Service menu for advanced users.
* 5 year warranty.
In Auto mode there is no need any attention from driver - fuel injection system will be automatically adjusted for current fuel (gasoline, E85 or any mixture) by lambda sensor. Just install-and-forget 
If your car have no lambda sensor, if this sensor is damaged, or if your ECU can not self-adjust for any other reasons, you can switch fuel modes manualy. There is another 3 presets: Gasoline, E85 and Ethanol for this mode.
Adapter have 4 independent channels, so it can be used with monoinjectors and semisequential systems, and with 1, 2, 3 or 4 cylinder engines.
Also it can be used with 6 and 8 cyl. engines - just install 2 BIO adapters, for 12 cyl - 3 BIO adapters
Cold start function is used for start cold engine in extremally cold weather. Any additional wiring to cabin or engine.
In this mode adapter will add more fuel till cranking and till first 1 minute after engine start - this will decrease engine warming time and increase driveability on cold engine. With this function engine can be started in -10...-15C on E85 fuel without any problems, and even in lower temperatures on "winter blends" of E85 fuel.
All presets and cold start function can be adjusted from service menu - please read user manual for it. There is no need to use computer or other external devices for it.
BIO adapter can be equipped with already installed Bosch EV1 and Delphi injector connectors, other types of connectors will be aviable soon.

Thanks for bringing this to our attention.
I also thank you for checking with me before you posted the thread.
I am sure your cold start experience will be useful to American users of E85 in the northern part of the country.
Could you give a quick summary of what is involved in the install?

Obormot-- i did not see in the forum links where you had mention of using the kit on a boosted factory 4 cyl.
Have you tested it on such a system and feel very comfortable with it on E70-E85?
Specifically the 2004 Saab Aero 2T (the one rated 210 hp)? I am not sure how much difference the US model is to the Swede version though I think both were built in Trollhatten. |

we used it on turbocharged Peugeot 406 2.0 Ti - everything is fine.

hi, so what do i need to make this work on a 4.0 l cherokee? which connectors, any addapters (i have no idea if its sequential/ semisequential or whatever)?whats the cost?
also (maybe i can start new year a little wiser): will that work with stock injectors? assuming you want to keep duty under 80% and 1 lambda is 1:9 for ethanol and 14.7 for gas you need 40% more fuel (14.7 : 9 x 0.85), so you figure the stock duty is under 60% max?
i also wonder: if alcohols have a faster flame speed then gas, why do they then detonate less?
im really new to this topic, so please excuse if above is somewhat stupid.
hapy new year! |

Welcome to the board. I can answer a few of your questions will leave the conversion specific questions to others.
Yes E85 has a faster flame speed at max power rich fuel mixtures, but at lean cruise mixtures the flame speed is very similar to gasoline.
The reason they do not detonate is they have higher octane than most commercially available gasoline. Detonation and flame speed have little relationship. In fact it goes in the opposite direction you imply.
Faster burn speed gives less time for the partial decomposition reactions that lead to detonation. This is why detonation is more likely at low rpm heavy load. The lower engine rpm means the fuel air mixture spends more time at high temperature and pressure. It is the high temperature and pressure that lead to detonation if a fuel is prone to it. In fact at very high rpm like used in F1, the engines have very low octane requirements because the combustion process occurs so quickly.
E85 has higher cooling due to evaporation than gasoline so actual exhaust gas temperatures typically go down about 200 degrees compared to gasoline. This combined with its high octane is why it is very resistant to detonation except in extreme applications like high boost and very high compression ratio engines.

hm, so im wiser already. it makes sense, thats why you increase timing with rpm.
on the other hand, i always thought, flame speed increases with compression (boost) and thats why the timing has to be decreased. is that wrong? |

Yes that is true, but you have to include all the variables, you cannot look at only one thing in isolation. Higher boost (pressure and usually intake air temp) will speed up the burn rate, as will the generally richer fuel air mixtures run at high boost. Each engine and situation is a bit different so you need to look at what the engine actually wants vs what some rule of thumb tells you is "likely".
Each engine has an ideal pressure angle (angle of the crank and connecting rods at peak cylinder pressure). You need to make what ever changes are required to get your peak pressure at that point in the power stroke. Sometimes that means dial in more advance (if the fuel will allow it), sometimes it means retard the timing, or cool things down (which slows combustion) with a richer mixture. Mixture changes also change your effective ignition timing. If you change one you sometimes need to tweak the other to compensate.
