How do we use HHO with diesel engines?
Recently we tried to add HHO to a 12 HP single cylinder diesel engine. The engine appears to use more fuel with HHO than without? We are adding the HHO to the air intake of the engine.
We currently build cells using KOH as electrolyte that generate over a liter a minute at 30 amps and 12 volts. But we have not had any luck with diesel engines. We would like to learn how to make HHO work with small and large diesel engines. Applications are diesel generator sets, fork lifts, earth moving machines, diggers, and trucks.
Appreciate any and all comments that will help us use HHO properly with diesel engines. Regards THM

We fed it over two liters per minute. The only load on the engine was a 30 amp alternator which was belt driven and not connected to anything. We didn't notice any change in engine tone or RPM.
The same amount of HHO was fed into the air intake of a gasoline engine, and the RPM's as well as the running tone changed. We are using KOH as an electrolyte, about 7 tablespoons per liter, it works a lot cleaner than NaOH, plus we get more HHO out of the cells.
The dry cells we use have 6 stainless 316L eight inch square electrodes, 1.5 mm thick. Spacing is 1mm polypropylene gasket. We are using a hydrogen boost PWM which controls current well.
This may be of some help to you
I was also puzzled over why more isn't better but the guy right above me probably knows a lot more than I do. I learned a lot from the link below this message, they've been doing HHO for a long time and have done a lot of research with it. Probably one of the giants in the industry.

Very interesting Mr myoldyourgold. Many thanks. I have a 2005 passat TDI ...

Here are three options but with out a load none might work:
1. Lower the amount of HHO so it draws about 5 to 7 amps. 1% electrolyte mixture and try again. It is difficult with the small diesels if you can not change the amount of diesel being used. You will need very little HHO. To measure if it is doing any good with out a load will be impossible.
2. Run some of the exhaust back into the intake and use the same amount of HHO you are putting in now. Keep adding more and more exhaust until it starts to run bad and then reduce the exhaust going into the engine until it is smooth. You still might need to reduce the HHO too but maybe not. Again you need a load on the engine to do this right.
3. The last option is spray a little water into the intake with the same 30 amps of HHO with a spray bottle or use a paint spray gun and a separate compressor. Be careful not to get to much water because it needs just a little to make it work. I prefer exhaust and water together but will be hard to control on a small engine like this.
What is happening with the exhaust/water is you are slowing down the burn of HHO and increasing HP with steam yielding more torque and HP. When done right you get more power over a larger crank angle. Depending on what the governor does will determine the amount of fuel saving if any. The governor is most likely controlled by rpm, centrifugal weights, and you will need to put a load on the engine to see any gain.
To measure fuel savings on a governed diesel you need to put a load on it. Other wise you will not be able to tell if you are saving or not.
Larger diesels that have much more torque are easier to get reasonable savings. The hardest ones to do though are generating sets because of the governor and the fact that they need to run at a given rpm range. You have no control over the throttle which complicates it even more or makes it impossible. Because HHO/water/exhaust gas increases torque and HP in diesels the engine can run at lower rpms and make the same HP but this can not be done on a generating setup because the generator needs to run within a certain rpm range set by the manufacture, so unless you can lower the amount of fuel some way and keep the rpm in the right range you will see no gains. Diesels are very efficient engines and just a better burn will yield no measurable gain.
Hello. I have a vw passat tdi in running order with no mods yet. I would like to have a check list of everything that need to be done to get it to work and what should be the expected increase in performance. The production of the HHO is not to be discussed other than specifying the amount required at various mass airflow settings. Thanks and regards.
