Propane is different than natural gas, but yes I'm sure the power is lessThe propane engines are a little less powerful than gasoline. This may have changed with new technology. I seem to remember about a 10% drop.
Sparkplugs, the engine and the oil last much longer since propane burns cleaner.
My gramps ran it in his Soviet Ladas and Volga's since the 1970sI'm very interested in this also.
There is a C.N.G. filling station directly across from the airport I work.I have seen C.N.G . limos.
Govt auctions often have the low mileage C.N.G. Honda Civics for sale.
I would prefer dual fuel capability myself.
The Australians have a few guys running propane or C.N.G I believe.
Yupp, the tanks are totally different. CNG tanks are extremely high pressure. Propane not so high. We had two tow trucks with same engine, One propane, one gasoline. Propane was a little less expensive to buy but vehicle burned a little more propane than gasoline one. Overall it was less expensive to operate.Propane is different than natural gas, but yes I'm sure the power is less
Now that I think of it, I believe you are right it was 30%.My gramps ran it in his Soviet Ladas and Volga's since the 1970s
Had some Italian kit juryrigged in... Pretty sure that one was for carburettor cars only, though. And it took up half his trunk with the tank.
Had on - the - fly dash mounted switch between petrol-gas and gas-gas. Downside: about 30% drop in horsepower/torque on gasgas.
Heard of but never saw personally: new European kits with custom tanks that fit without eating up trunk space, slotting into the space for a full size spare tire.
It's been about twenty years since we did our decidedly unscientific comparisons. In our case it may have been like you said 10% loss, maybe I'm remembering the difference in cost per gallon at 30%. It's been a long time.About 10 years ago I did extensive research on power output differences between Gasoline and Propane and Natural Gas.
Power output is 10% less with Propane than Gasoline
Power output is 20% less with Natural Gas than Gasoline.
However, the engine will last about 15% longer with EITHER Propane or Natural Gas with all maintenance being performed per recommended intervals.
I've read that 30% figure before somewhere.Gramps Lada had either 54 or 68 bhp...maybe it just FELT like 30%?
