Once again I thank the Honda Engineers that designed the systems of the carbed cars.
Special thanks for the hot air source in the exhaust manifold.
As I have documented here in this forum, not using that hot air source during winter can reduce the fuel economy in 15-20%.
The next project is based in all my reading over internet about ways to improve fuel economy, increase power or both. We'll see.
We all should be more or less familiar with the Water Injection concept. If not, anybody interested can google search and find lots of information.
Did read similar thing but they use already vaporized water and I said "this is something I can implement pretty quick in my car" since:
I have the windshield washer motor and water tank.
I have the hot air source working properly
I have a controller that can automatically trigger the water injection at any given condition.
The plan is to inject the water into the exhaust manifold (near the O2 sensor location), and collect the vapor generated through the hot air hose.
I can add a PWM controller to the little pump of the windshield washer, proportional to the engine RPM or TPS or whatever.
I am already controlling the hot/cold air door in the filter case if I ever need to mix vapor and ambient air.
In summary, its just a matter to connect one hose (and a nozzle) from the windshield washer tank to the air heater and wire a SW to the cabin to trigger the water pump at my convenience and start getting some initial parameters.
