Ok, my discussion on the computer integration section recently yielded the fact that I also need an EFIE to go along w/my map sensor if I am finally able to realize any mileage gains. I have visited ebay, the for sale section here and now want to give this board a chance to voice their knowledge and facts before I purchase what I need.
PWM - my car is a 2001 Acura Integra w/a 1.8L engine and a 20 amp power supply. I want to run my dry cell (testing stage, currently using water4gas) at the full 28% KOH concentration to allow for a more efficient operation and maximum freeze protection for winter operation. I want one that is a set it and forget it type. Some of the less expensive ones I suspect are of lower quality materials. Anybody know what weight of KOH flakes = 28% in a gallon of DI? For testing and breaking in purposes I'm currently using 3 level teaspoons of KOH/gallon. It's working well, but the 28% is my goal.
EFIE - I need one single narrow band EFIE. I mistakenly thought the map sensor was sufficient, but with all the tinkering done so far, little to no gains have me searching again. I know the water4gas design (6 cells) are producing combustable HHO because of my flash tests, so even with those I should be seeing something. I am getting 5-6 mpg more that the government figures, but I was getting that b4 the water4gas intro. I drive precipitously. Coast down hills, coast to stop lights, slow takeoffs etc.
H2OPWR/Larry,
I did a prefill of the cell for leak testing - one small drop developed, so I retightened the bolts and then retested, even pressure tested and no leaks developed so I set it up for the bench testing the next day.
Testing began on the dry cell yesterday at work and it went really well. I realize w/the 3 tsps/gallon that it would be a lower production rate than the 28% so that was not surprising. The consistent supply of HHO was refreshing. My flash tests showed as in the water4gas that the combustable HHO is not immediate, but quicker. I'm sure some air is still getting expelled. As the cell ran the flash became more pronounced and louder. Prior to shutting down (3hr. run) the flash tests were more like firecrackers going off. This is a much more powerful HHO than I've ever experienced w/water4gas cells. Some other things to note, the battery went from 12.22 v down to 12.15 at shutdown. The voltage between my cell plates were right at the 2.00-2.02v, then even dropping to 1.99 prior to shutdown. I measured 13.9 volts for my car supply, so this is an area that bolds well for improved production upon installation. Also, the temperature went from 70F to 82F in 3 hrs. time, I know thats low, but also the electrolite concentration is low, voltage supply is low and the gaskets are thinner, all of these are contributing to lower operating temps. I did get some foaming. In the bottom of the reservoir I mounted a "cap" w/numerous small holes that help disburse the bubbling and it seems to work well. The reservoir is hung, so raising and lowering can be done easily while operating. The best flow seemed to be w/the reservoir just above the cells top. The dry cell appeared to stay flooded, kudos to the 5/16" effluent/influent holes. Thanks for the help.
I plan to recharge the battery next shift, then run the following shift, I'll do that for another week or so then go for the install.
Thanks everyone for your inputs,
