A few months ago i saw a new Volvo tractor making a delivery at a store and saw some stuff hanging on the frame rails I didn't recognize. I took a closer look and started seeing stickers that stated it was powered by compressed natural gas. There were plastic panels hiding the oval saddle tanks and upon closer look I could see the fill ports. There wasn't much else to see. I waited until it pulled out, it didn't sound like a diesel yet didn't sound like the gas engines I used to hear either. I do believe it was a 6 though from the sound.
I've been curious about this truck ever since I saw it. I wonder about the ignition, spark or compression? Displacement? Power specs? Has anyone else seen one?
