A switch-mode DC-DC boost converter could do this; however if you need 20A at 24V and the if the converter was 100% efficient, then the input current would be 40A at 12V. Does your existing car's alternator have 40A of spare capacity? I'll bet not.what's the most cost effective way of doing this?
minimum continuous output current: 20A
Inverter and a diode bridge?
I've already converted my father's Toyota Truck.Most of the HHO scams use only 2V to make hydrogen.
sure.. why don't u try it and monitor the EGT at the same time. It would be fun to see the gauge.Since you've modified the O2 sensor you'd get better mileage without the HHO.
