HHO Control To Save Gas

This HHO Control blog is dedicated for those adventurous HHO gas pioneers,  HHO diys who advocate saving engine fuel using HHO concept and help cut vehicle emission.

The HHO control came about as soon as HHO cell started producing oxyhydrogen gas on demand to interract with the vehicle’s engine control module (ECM) or your engine computer. If you recall last year, when the HHO cell introduced these gases into your combustion chamber; the engine computer will react to the leaning effect of the hho gas to your engine fuel mixture. At the same time, it has to contend also to the higher temperature levels brought about by the oxygenhydrogen gases to both the HHO cell unit and your engine combustion chamber.

Without HHO control, higher HHO cell temperature results in early deterioration of the HHO cell plate wiring terminals and discoloration of the HHO cell fluids. This was corrected by using the PMW device to control the cell amperage and converting it to “dry type cell” system which allowed more metal plates without raising the cell housing temperature. A user friendly hho cell additive like soda was added to the” wet type”  HHO cell fluid to improve HHO cell production and improve maintenance since it minimizes the cleaning time to flush dirty contaminants inside the HHO cell. These strategies have allowed a much lower operating temperature for the HHO cell and at the same time, allowed a higher HHO cell flow rate production.

The same technique was also used to control the HHO gases in the combustion chamber by using the following engine sensor enhancement devices which you probably know are already being used extensively:

EFIE enhancer which controls the oxygen gas content of the combustion gas to prevent the engine ecm from going open loop when the fuel mixture becomes lean as a result of hho gas injection.

Map/Maf sensor enhancer which control the sensor frequency output and map sensor load voltage at a level tolerable to the ecm management specs again to prevent the fuel mixture control system into going open loop.

Finally, a scan gauge is used to monitor the engine performance when oxy hydrogen gases are introduced. However, HHO control is done by adjusting the PWM, EFIE and MAP/MAF settings using the adjuster knobs that came with these enhancement devices.

As you will see in my next blog, there is no automatic HHO control in this above method. A better electronic controller is needed so that the HHO cell gas production is optimized based on the existing condition of the vehicle engine.
