another form a hall effect sensor is coupled to the fuel injector input the output from the hall effect sensor is then used to regulate the pulse width of the wave signal controlling the hydrogen generator 36 at idle the positive portion of the wave sent to the injector will be quite short in duration and when power is applied the engine the positive portion of the wave will be considerably longer the fuel injector signal therefore defines the power control signal sent to the hydrogen generator either directly to the anode cathode or to the control box 52 which in turn powers the hydrogen generator 36 while many common hall effect sensors will not be capable of surviving the heat generated by an internal combustion engine hall effect sensors built for industrial or military use are normally capable of handling such environments in one form the electrolyte stabilization tank 24 contains a chemical solution which is pumped from the water supply outlet 40 through the hydrogen generator 36 to release hho gas the hho gas released by the hydrogen generator 36 and any remaining liquid therein is then returned to the stabilization tank 24 through the supply outlet 58 to the inlet 34 for optimum performance the position of the hho inlet 34 is above the normal operating fluid level in the.
