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.

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.
