On the other hand, I've often wondered if injecting a LITTLE water wouldn't be very good for mileage. My dad experimented with it and found that it did increase his MPG by a few small numbers: 2 or 3 MPG. The (somewhat reasonable) argument is that the fire in the cylinder is hotter than it needs to be (obvious since the cars cooling system is pretty much non-optional) and that the extra heat can be used to boil off some water, increasing the volumn of gasses expanding and the pressure. Too much water injected will lower the internal temperature to a point where combustion will be incomplete and expansion and pressure will decrease. There may be other negative side effects of the injected water such as calcification and other crap building up on the cylinder crown and inside the head. But the cooling is interesting to me... I wonder if you could make an air cooled, high power engine where the bulk of the cooling is actually done by injecting water... -- James. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Apptech Sent: Friday, December 21, 2007 03:23 To: PIC List Subject: [EE]:: Convert your car to burn water as well as gas.
