What? Very few vehicles run LPG in the US. The difference in cost between LPG and regular unleaded does not make it worthwhile. I know because I bought a 75 Jaguar XJ12C with an LPG conversion and the first thing I did was convert it back. It took some effort to go back as I had to source a fuel rail, injectors, wiring harness, computer and fuel tanks. Why? because if I ever run out of fuel, I would like to have the option of walking off and finding the nearest gas station and coming back with a jerry can.Mitsuru wrote: ↑Tue May 30, 2017 1:20 amConsidering the title and enquiry is about 'cleaner emissions'.
If the car is standard petrol or diesel, the surely you need to be looking at adding LPG. As in the USA they run LPG in with the diesel to give a cleaner burn & makes it more efficient. But unlike diesel powered vehicles, petrol powered vehicles can run soley on LPG.
For anyone considering LPG in the US would be better off going with E85 as it's a cheaper option and makes more sense. Most petrol powered pickup and SUV's already run flex fuel so there is no changes required to the cars or special handling. You just pour it in the petrol tank and that's it.
Converting a diesel to LPG makes even less sense. Where are you going to drill the spark plug holes?
CNG is used in the US mostly by government, running buses or city fleet vehicles. Characteristics are different and while LPG can be dual fuel (LPG and petrol), I've only CNG vehicles that run only CNG. In my 17 years of living in the US, I have not seen any commercial filling stations that sell CNG.Mitsuru wrote: ↑Tue May 30, 2017 1:20 am
If I remember correctly vehicles which run on LPG have greatly reduced emissions compared to that of petrol. And the efficiency depends on the kit used. Added bonus LPG is half the price of petrol. The LPG kit is also very similar to CNG and both I think are if the vehicle runs on the supposed to be exempt aren't they?
