[CNGBiFuel]

Differences between LPG & CNG with respect to Necam.

After the high-pressure regulator these systems are much the same. It's only the minor ignition and burn characteristics of the two fuels that makes for minor cahnges. Save for ECU differnces to account for this, with the aforementioned exception, mechanically they are identical.

There is an earlier type of vaporiser. I've put the later vapouriser on an early car simply because I had it to hand. To further comfuse, early vapourisers in CNG have Red stickerage.
