Yeah appologies it got a bit confusing considering gas and atomised liquid petrol. I'm trying to explain how much HHO gas by volume, would be required to run an engine.

I went on to write.

That 2 litres of fuel or 2 litres of LPG is then atomised to represent 15% of the air fuel mixure - petrol and LPG are both stored as liquids. 2 litres of gas from the HHO cell, then mixed into the volume of air passing through the engine would be vastly underpowering the car. If your supplying gas then you need to constantly supply 15% of the volume of air fuel. As it can be seen above - this is way more than 2 litres per min.

My 2.2 litre car has a fuel pump delivery rate of about 2 litres per min of petrol. Thats required at maximum load. That petrol is then atomised to 15% of the air fuel in a 1 Litre cylinder.

Powering a car on HHO would require similar volumes of HHO gas to atomised petrol.

I'm trying to compare 15% volume of HHO gas in 1 litre of air fuel mixture to 2 litres per min of petrol, then atomised. ( I use atomised to describe the carburetion process)

I've also got a 2.6 litre car running on LPG, it has a 90 Litre tank which gives me about 250 miles (Rough guesstimate) The LPG is stored as liquid and then heated before entering the engine.

So how many litres of gas, does 90 litres of LPG make when its heated? Thats how much HHO has to be produced for the engine.

Any help appreciated.
