What Does A Pulse Width Modulator Do?

                   A pulse width modulator regulates the amount of electrical current delivered to an HHO generator.    As a dry cell of an HHO generator produces HHO (oxy-hydrogen) gas, the dry cell heats up.   As the dry cell heats up,  HHO gas production becomes less efficient and demands more electrical current to maintain the same level of hydrogen gas production.   Every dry cell has its optimum efficiency of HHO gas production as defined as amp hours/liter of HHO gas.   Also every gas/diesel engine, given a range of rpm and torque of the said engine, has an optimum amount of HHO measured in liters per minute to achieve that engine’s maximum efficiency of power production with supplemental hydrogen. A pulse width modulator HHO allows one to control not only the amount of electrical current delivered to an HHO generator, but also the amount of HHO gas produced by the HHO dry cell.  This kind of HHO generator pulse width modulator is also called a constant current PWM (pulse width modulator) .

Why Is An LCD Monitor Necessary?

               A complete HHO generator kit includes a PWM controller with a dashmount LCD monitor.  Without a dashboard mount LCD monitor, there is no other practical way of knowing at any given time what precise amount of electrical current is being used by an HHO system.  The LCD monitor allows the driver to have “cockpit” control and monitoring of the electrical current and HHO gas production of an HHO gas system.

 Will Constant Current Pulse Width Modulator Be Replaced By Smart PWM Controller

It is highly probable that will be the case.  However, many HHO generator kits continue to be sold as complete systems without a PWM pulse width modulator to begin with.  A pulse width modulator circuit is a basic necessity for HHO car kits. A smart PWM is a substantial improvement on the basics.  For now, truck operators are the ones who realize the greatest need for them.
