So you have a CNG powered car. Where are you going to refuel it when you travel and are you willing to invest in the expensive equipment to fuel it at home ? City bus will work well because A, it returns to the garage where expensive tax payer equipment can refuel it quickly and B, it doesn’t travel too far away from the garage.
In essence you have a single use vehicle. No long trips and lots of refueling time. Sounds like an EV to me and a Prius sounds like a better “investment” if that’s what you want to call it.
@MikeInNH…“Years ago there were conversion kits for Carburated cars.”
Mike, my Yamaha generator has a conversion kit to LP or CNG. You drill a hole down through the carb and thread a tube in with a regulator on the end. I doubt that a fuel injection system replacement would lend itself to such easy procedures. Granted, this generator is is a single cylinder but the same comparison can be made for cars too. Wouldn’t all those emission control sensors have somkething to say about it too ?..And don’t forget HAL, the car’s computer.
