The Smart PWM
Eight years ago, we started selling a high quality CCPWM. At the time we educated our public on the need for the CCPWM over the manual PWMs that were prevalent at the time. Other shops even sold their non-constant current PWMs as being constant current because people just didn't know what a constant current PWM was. They didn't know that a constant current PWM will make adjustments automatically so that the output amperage and HHO product remain constant. Or they thought that by watching an amp gauge and making constant adjustments by hand of the PWM's knob, that the PWM was constant current. This is not just the public, mind you, but HHO shop owners as well.
Now daya, people take for granted that the constant current PWM is the correct power source for an HHO system. Only by having a system that automatically stays adjusted can the gains be consistent, and also the driver can just drive his car without having to constantly fiddle with his HHO system. We have arrived in the modern era.
Or have we?
A Quantum Leap in PWM Technology
Lets take a closer look at the CCPWM. Is it really the optimum solution? Lets look at some of the possible shortcomings of the CCPWM:
The first problem with a constant current PWM (CCPWM), is that you don't always need the same number of amps. For instance, the amount of HHO you need is based most of all on the engine RPM. If you have high engine RPMs, you need more HHO to maintain the correct HHO to air ratio going into the engine. Likewise at low RPMs, or at idle, you need much less HHO. Yet the CCPWM puts out a constant supply of HHO for all engine speeds. Wouldn't it be smarter if the PWM could adjust to the speed of the engine to maintain the same HHO to air ratio?
The next problem with a CCPWM is that the engine demand for fuel is often different, even at the same RPMs. For instance, you can have high RPMs, but low demand, such as when you are going down a hill. Why waste the energy to make HHO when you are not actually using your engine. Or likewise, when you are under heavy load but relatively low RPMs, such as when going uphill or pulling a load. Wouldn't it be smarter to adjust the HHO production based on the engine's load?
Finally, the driver is asking for different amounts of power. This shows up at the throttle position sensor. Wouldn't it be a smarter PWM if it could sense when the driver needed more power and make adjustments for the driver's demand?
Hindsight is 20-20. But in retrospect, it is quite clear that using the same HHO production for all engine conditions is just not the optimum solution. We need a smarter PWM.
A New Breed of PWM is Born
Enter our new Smart PWM. The Smart PWM is designed to vary it's production to meet the constantly changing requirements of the engine. It will make adjustments to the HHO production based on engine RPMs, engine load, and driver demand. With the Smart PWM, you don't set a current that will be held the same under all conditions. Instead you set the current you want for your normal cruising speed and conditions. Then you set the PWM to make adjustments to that baseline production based on the above 3 factors. For the first time, the engine will truly be getting the correct amount of HHO for all engine conditions.
The smart PWM is to a CCPWM what a CCPWM is to a manual PWM. While this new PWM is loaded with bells and whistles, what makes it a quantum leap in PWM design is its ability to adjust it's production to the varying conditions of the engine. This is it's super power. This is what makes it the new standard for PWM design in the twenty-first century.
But lets face it. We also love bells and whistles too, don't we? And this product is packed with them. Here are some of it's features:
