HHO Control

This is part 2 HHO control blog for those gas saving driver enthusiasts.

When automatic HHO control was introduced early last year by Hydroxy Technologies Corporation (HTC), it caught everybody by surprise including myself. Up to that time a year ago, almost everybody was using a remote scan gauge and manually adjusting the sensor enhancer settings using their sensor enhancer adjusting knobs. This means, if you happened to forget to set your PMW properly and it happens that your HHO cell is overheating then you can say goodbye to your HHO cell. The same case can occur if the oxygen sensor is allowed to run in an open loop because the HHO EFIE setting is not set up accurately. This is true if the fuel mixture is lean and there is a big chance that you might damage your engine.

The main advantage of this automatic HHO control is the ability of the HHO cell to produce the right amount of oxyhydrogen gases for your engine. This is done by automatically adjusting all the sensor parameters at HHO cell start ups and set according to the vehicle driving conditions. Example: if the engine is idling, the HHO cell production is not needed and the PWM is set to limit hho gas entry to the combustion chamber. On the other hand, if the engine is revving high and running under load, the HHO cell gas production must be set high by the PWM device at a higher rate.

How does automatic HHO control works?

Instead of using a scan gage to monitor engine performance, a remote engine controller is mounted in your dash for you to monitor. Using transistors and electronic circuit board, all the sensor enhancer devices are hooked up into this controller including the engine rpm, hho unit temperature and OBD2 engine configuration of the ecm thru a wiring harness plugin. Using this system, one can set the HHO enhancer parameter reading/s at one sitting and there is no need to do any adjustment anymore unless the controller gives a signal for you to do otherwise. This means, a trouble free operation that will not damaged your engine including less HHO cell maintenance.

Note:

Sine the HHO cell hho gas production is controlled, less contaminants are produced inside the hho cell unit.

This HHO control device is called Vehicle Management Unit or VMU by HTC and shown below is a UTube video on how it works:

Feel free to ask ATS for wiring diagram for your engine if it is applicable to use this HHO control system for your vehicle.

Thanks!
