Re: [Biofuel] Fwd: New Engine 100 MPG
I expect to be picking up my 'new' ride this coming Sunday. http://www.econogics.com/ev/Solo%20Electra/LeftSide.jpg 1974 Solo Electra e-bike (supposedly 25 km/charge, 25 km/h max speed). On-board battery capacity is about 1 kWh, so running the numbers (to be confirmed in real-life use), it should consume about 40 watt-hours per km. Unless I actually pedal, which should reduce the electrical energy consumption (substituting energy from the much less efficient meat engine). 40 watt-hours per km = 64 Wh/mile (1 mile = 1.6 km) 64 Wh/mile = 218 BTU/mile (1 Wh = 0.2931 BTU) A U.S. gallon of gasoline = 114,000 BTU (approximately) 218/114,000 = 0.00052 gallons/mile Reciprocal to get mpg: about 1,900 mpg That's energy equivalency. It does not take into account that the e-bike is zero emissions at point of use, and the primary form of electrical generation locally is hydro. I expect this vehicle will be adequate for my regular local errands. I expect the rear rack will accept my largish bicycle panniers, which will increase my grocery carrying capacity vs. walking (no cart). Incidentally, my son is now commuting by e-bike pretty regularly. http://www.econogics.com/ev/evbikes.htm (scroll down about 2/3's of the way to see an image of his bike). He does appreciate the irony that his job is about the use and maintenance of aircraft, any one of which will burn more petro fuel in an hour than he is saving in a season of e-commuting.

Regardless of every sane argument I need to drive to make a living. To pay the house I live in, to pay for my internet connection, you get it, I believe. I need to drive a lot some days. I need to carry tools sometimes. I need to be on time and I'm hot. So yes, its 33 deg C out there, and the humidity is high, and aircon helps a lot. I work 13-14 hours some days, staying cool during drives helps to stay alert on the road. So yes, I not only believe aircon is nice, I believe it's neccessary on some days. Traffic is heavy only some days, but mostly very bearable where I live. The most we need to take real good care of these days are the cyclists. These are not people getting from A to B, these are people with nothing to do all afternoon and they didn't tire themselves during their work day. But I still take care. So yes, passive and active safety elements in cars are essential. And we don't have tank traffic at all. We don't even have many tanks left anymore. There are some large vehicles on road and I happen to own one. And no, it's not putting in danger any one, it's rather useful for that matter.

Why all these inventions? Why indeed? You can buy a whole production car capable of 100 mpg today. Unfortunately it is fundamentally one of several million of them, and done that way can't be otherwise. The world record in fuel economy set by Gerhardt Plattner with this car is actually way better: 107 mpg from austria to denmark and back, 2007 km on 45 litres of diesel, using autobahns, climbing mountain highway passes etc. http://carscoop.blogspot.com/2011/05/gerhard-plattner-does-it-again-drives.html (7% better fuel economy at these low values is no easy job in real world traffic) It's not a hybrid. Good. It's got aircon and everything a modern car should have. Should a modern car have aircon and everything else? Why? Perhaps because it spends so much time in heavy traffic? Isn't THAT rather the problem? It hasn't got an exotic engine, the engine is a common rail 1.2 litre tdi. That's one common rail too exotic! It's even almost half reasonably priced. And it's not even a kei or very small car : Skoda Fabia Greenline II http://www.buyacar.co.uk/cars/skoda/skoda_fabia/review_skoda_fabia_greenline_ii_4637.jhtml Primarily because it needs to 'protect' its occupants against all that tank traffic ... Cheers, Aleks This looks like a lot of fun to me. Seventeen of them might achieve remarkable fuel economy; no great matter if the eighteenth and nineteenth don't. And they would achieve that fuel economy the right way, that is, pretty much by accident. Regards Dawie From: Aleksander Kac[EMAIL

[Biofuel] Emulsion fuels (diesel)
Does anyone have any experience with water-diesel emulsion fuel? If so, what is your experience with it? I am working with a group that is just starting investigation of one variety. We got a sample of the emulsified fuel, and burned it in open air and then did the same with regular diesel. The emulsified fuel seemed to burn cooler and with much less soot. This was a 30% water, 70% diesel mix. (The emulsifier agent is apparently about 1/100th of 1% of the volume.) I expect we'll be doing more investigation, but I was looking for knowledge already acquired by others. I guess it's time to dig the old Lombardini diesel I salvaged a few years ago and see if I can get it to go. Not only will it allow me to do some testing (regular, bio and emulsified diesel), but it is part of my long-range plan for charging the 12-volt battery bank for household backup power. So many projects, so little time. -- Darryl McMahon Author, The Emperor's New Hydrogen Economy ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] Emulsion fuels (diesel)
when I was repairing large diesel engines, a common problem to be fixed was water in the fuel that damaged the injector tips. Granted that was in the days when diesel injectors were built very similar to a syringe where fluid filled a cylinder and was injected by cam action and a plunger. After replacing the missing injector tip, we hoped that the unattached metal parts didnt bend a valve, destroy a valve seat or wipe out the turbocharger when it exited the engine. but the high performance folks who take part in tractor and truck pulls use water injection as a method of gaining more horsepower. Water injected into the cylinder thru the air intake would flash into steam in the combustion chamber. The rapid expansion of gasses would produce more work.

Re: [Biofuel] Emulsion fuels (diesel)
Hi Randy Water in suspension is not the same as water held in an emulsion. Eg: Water Content - If emulgated [emulsified], a higher water content is not disadvantageous (as long the emulgation remains stable, which is very difficult). Normally water will cause problems anywhere in the fuel system. -- Comments from Elsbett Technologie on the German PPO fuel standard: Quality Standard for Rapeseed Oil as a Fuel http://journeytoforever.org//biodiesel_svostd.html#vegstd There's quite a lot of discussion about this in the list archives.

Re: [Biofuel] Emulsion fuels (diesel)
It lowered EGTs at the same time. And it only works at WOT and full boost otherwise it tends to put the fire out. Steam content spins the turbo faster, which increases boost and water content (both combined) allow for an increased fueling rate. expanding Steam also increases the volume without increasing the pressure inside of the combustion chanber. Water injection Alcohol injection Nitrous Oxide Injection Propane injection all are short term methods of boosting power. They arent by any definition efficient for long term use and they dont promote fuel economy (because it relys on the 1950 - 60 - 70's methods of overfueling to make HP) but they work to make the motor put out more power.They were most commonly used by OTR truckers using naturally aspirated or mechanical governor turbocharged diesel engines while pulling mountain grades. Water and Alcohol/water injection was the most engine component friendly version. Modern engine Technology has turned out factory stock pickup truck inline 6 diesels that put out more HP potential than was ever achieved from Shadetree gimicks on class 8 trucks in the 60's.
