Hi all,
just a few thoughts for those considering running a generator on LPG.
There is nothing wrong with this, but, using a dual fuel petrol/LPG set-up is not as efficient as running with one or the other, exclusively.
Each fuel has it's own merits/requirements. In particular, LPG runs more efficiently on a compression ratio (CR) of around 14:1.
So, if you are running dual fuel petrol/LPG the CR will be about 9:1, thus favouring petrol.
Unless you can purchase a generator, purpose built for LPG, or, can modify an existing petrol engine, then you are not using the LPG, as efficiently as you might.
Should anyone choose to go with an LPG only set-up, installing two 47kg cylinders is, economically, the way to go.
If you can squeeze then in(!), the filling cost of 47kg cylinders is a smaller proportion of the overall gas cost, when compared with smaller cylinders.
I hope this helps.
