Installation guidelines:

Installing a Brown Gas generator system is not a difficult task, but it requires some electrical and mechanical knowledge.

First of all, You need to find the proper place where to install the cell, the reservoir and the bubler.  On cars this is usually between the bumper cover and the radiator, or behind the bumper and the splash guard of the wheel. If you don’t find space, you can install it also in the trunk of the vehicle. ( check the gallery for more details as one picture counts for 1000 words ), but you will need to run more cable and tubes.


As water is supplied to the cell by gravity, it is necessary the reservoir to be above the level of the cell with at least 10-20cm. The bubblers are positioned close to the reservoir on convenient place, not to obstruct access to dipsticks of filter b
oxes, plus avoid any hot spots.

After finding the right place for the different parts of the system you need to secure them in order to prevent any eventual movement during vehicle’s operation. The use of any metal brackets and straps is appropriate. Use your common sense to do this.

Usually this first step is the most time consuming as it sometimes needs removing of the front bumper, or other parts that hinder access. For trucks the systems come already assembled in a metal box, which should be secured tightly to the chassis or other place of convenience.

The second step is to connect the tubes and the wires.

All kits come with “push-in” connectors for the tubes which make your task easier. Follow the diagram below for the right routing of the tubes. Start plugging the tubes from the cell and measure then cut the length you need. The last element of the tubing is to make and install the connector to the intake manifold. The most appropriate place for this is after your MAF(Mass Air Flow Sensor) and before the throttle body assembly. Just take a small drill bit and make a hole in the rubber pipe conducting air from the air filter box. Then insert the connector provided  and apply some silicone if needed.

Electrical connections are easy to be done. Follow the schema below. Although the schema does not require a relay, because we use a dynamic PWM, it is your decision whether to include one or not. Controlling signal for the relay is usually taken from the fuel injection fuse or other “hot-in-run” fuse. The purpose is to make sure when the key is in “on “position, there is no production of HHO gas.


On the third place you need to fill the system with electrolyte. The kit is coming with a KOH.  Be careful as it is highly poisonous. When in contact with water it releases toxic vapor gases and heat. What you need to do is measure 1L of steam distilled water and dissolve KOH inside. The mixture should get hot from the chemical reaction.  Start with as little as 50gr of KOH in 1L of water. Depending on the outside weather temperatures you are expecting to run the vehicle, higher concentration may be needed in order to prevent the solution from freezing. For example if you are expecting temperatures of -20C or even lower, you can add about 200gr more. As a rule of thumb a solution of 25% will prevent freezing at -40C temperatures. We recommend flushing the system 500km after the installation and fill up with new solution. Before and after winter a change of electrolytes concentration should be made.

The final step is installing the Fuel saver chip or the EFIE, and adjusting the PWM to the right current.  The basic rule for current needed to produce enough HHO for you vehicle is 0.25 to 0.5L/per minute HHO Gas for each liter of engine size you have. In other word if you have 2l engine you will need from 0.5L/min to 1L/min HHO gas. The chart below will give you some guidance what AMPs are needed for your engine size in order the system to produce the necessary amount of gas. The best fuel savings though should be obtained when you try different currents and check the results you get afterwards.


If you install a dynamic PWM, it is necessary to set the minimum and the maximum currents. During vehicle operation currents automatically change according to the revolutions of the motor. This saves you headaches and also additional fuel. Above explanations what you are to expect when deciding to install a HHO system on your own. You can use the service of a specialized garage if you think it is too complicated or time consuming.We offer a complete installation and testing service in Montreal area.
