these are the results to date on the fogger in my fiat uno : 1) vehicle : fiat uno, 22,000 k. on the clock, 1.3 l. fuel injected, computer controlled, 95 octane gas, exhaust catalytic converter.
2) mission profile : 80 k.p.h. steady speed whenever possible. very hilly terrain. mild temperate weather. 3) fogger : straight water, one aquarium stone (2 cm. diameter x 4 cm. length), all piping 4.75 mm. (3/16") i.d. clear pvc tubing. fogger is connected directly to intake manifold, next to the power brake vacuum connection. 4) results so far : a) 09 jan 01 to 02 feb 01 (summer) : fogger ON - 865 k. - 51.88 l. - 16.67 k.p.l. (39.2 m.p.g.) b) 03 feb 01 to 30 mar 01 (end of summer) : fogger OFF - 753 k. - 50.28 l. - 14.98 k.p.l. (35.2 m.p.g.) c) 31 mar 01 to 27 apr 01 (early fall) : fogger ON - 672 k. - 41.77 l. - 16.09 k.p.l. (37.8 m.p.g.) 5) comments : fogger appears to be more effective at higher ambient temperatures, which is consistent with the latent heat theory. mileage improved + 7.4 % (low) and + 11. 3 % (high). this is consistent with results in novak's article. i do not use alcohol because i do not have freezing weather; alcohol having a lower latent heat than water, results would probably reflect this. oil remains noticeably cleaner, and in vehicles with high oil use (one liter/1000 k.), oil consumption is reduced by 50 %. this is probably due to a cleaner fire ring piston grove. spark plugs are of optimum color, and the central electrode remains clean. driving flexibility improves noticeably, and at lower r.p.m. there is no tendency to pre-ignition, even under extreme torque requirements. this is the first thing people notice when the unit is installed in their cars. foggers should bubble vigorously at idle. no valves are necessary. if the canister is too full of water, some droplets might be seen entering the engine, but no harm comes of this. water use varies according to the engine, and driving profile. higher in city driving, lower in highway driving (my case). high of one liter per 500 k., and low of one liter per 2000 k. why foggers are not standard factory equipment is beyond me....i suppose the nih (not invented here) syndrome might have something to do with this. car manufacturers are strange animals. i worked for a couple of them way back, and still wonder how they managed to build a car at all, with all the infighting going on all the time... happy fogging !!! cheers, dick.
