Thanks for the add. I like to tinker with cars, but usually more for performance than fuel mileage. My last project was supercharging my Honda civic for under $500. Couple videos from that project. https://youtube/watch?v=9wivFuyGYqw&list=UUVe_Msi4swt_bRPJON8JR0w https://youtube/watch?v=sd1xYytLV6k&list=UUVe_Msi4swt_bRPJON8JR0w My wife just started her new job today and has an hour commute one way. Her jeep averages 18-19MPG. That got me thinking about MPG and ways to increase it. I was thinking HHO using the exhaust to heat/boil the water and inject it as fuel. Well from what I have read the only way to split the atoms for HHO injection is through electrolysis. That is when I stumbled upon this page and the idea of gasoline vaporization. I sold the Civic last year and recently picked up a 2005 Acura RSX-S.(Same engine that was swapped into my civic). My wife never liked riding in the Civic. It was more of a track car, than a street car. No AC, PS and rough ride. So I got the Acura with plans to put my old supercharger on it, but instead I think I am going to keep it more streetable/low key and build a custom rear trunk mounted turbo, allowing me to make more power, keep AC, PS and cooler engine/intake temps. Rather then messing with my wifes new Jeep I had an idea to try some vapor injection on the RSX. It already gets 30MPG, but no such thing as too much MPG. The RSX is stock for now, but I have a few parts I have been gathering. One of which is a fully controllable/programmable and datalog capable Ktuner ECU. My basic idea, was a gasoline vapor injection using exhaust to heat gasoline in a container to create vapors. Have a solenoid tied to a thermostat of sorts that closes the solenoid and regulates the exhaust flow/ gasoline temp. Vapors would be pulled in from a vacuum port in the intake(flash back arrestor inline). The RSX has a factory wideband 02 sensor that is uses when cruising in closed loop to regulate the fuel injection and maintain the target AFR based on load and RPM. My theory is that injecting the gasoline vapor into the intake would cause the 02 sensor to read rich and trigger the short term fuel trim to pull back fuel from the injectors. This would in turn give better MPG as less liquid fuel would be used and a more efficient vapor burn would take place. Thoughts comments or suggestions?
