WVo should work.Ok, if converting a diesel to cng, could you also include a wvo system to ignite the cng? Also, since there are hp gains with cng, could you manually shutoff injectors to a few cylinders, to further decrease fuel consumption? Ie...variable displacement diesel that burns cleaner than prius lol, with maybe water/methanol injection to keep egt's low...:idea:
My cars use a simple aspirated system that feeds CNG in just before the turbo, so shutting off injectors would just be wasting CNG. If you went with a more expensive CNG system that used individual CNG injectors it might be possible.
I may pursue water injection on CNG in the future for fun. Not at all needed, but could allow for higher ratios of CNG in pulling or racing situations. ( neither of which apply to my daily drivers).
