Had it been the case of running on CNG, it would be easier to adapt a gasser to that old Vitara instead of a Diesel.

What's a bug engine? Or do you mean Bug engine as in VW Bug?

I guess it was Bug as in a VW Bug.

CR: nowhere you indicated it was a normally aspirated diesel but I assumed by 1600 cc you were saying pancake aircooled. But I have seen fuel injectors drilled and tapped into the main fuel plenum with a single large delivery nozzle and aftermarket injected throttle bodies.

I thought the D on 1.6D gave a clue of what I was refering to.

That's what I usually see on CNG conversions anyway. But converting a Diesel engine to dedicated-CNG is uncommon here, even though I remember seeing trucks fitted with a dual-fuel setup allowing them to use simultaneously Diesel fuel and CNG. IIRC there were some conversions from Diesel to dedicated-CNG in Argentina, but even the Argentinian vehicles running on CNG were based on an originally spark-ignited gasser.

CNG can tolerate higher compression than gasoline. So if you were to try to make a diesel quieter this fuel might be it's only chance without a whole lot more machining. Then again the 1.6L VW diesels had something like a 23:1 CR; way too much for even naturally aspirated CNG. The same goes for wood gas.

I have heard of "diesel ignited" CNG and wood gas. Basically the diesel system is left idling constantly for that little squirt to start the flame and power is regulated by adjusting how much CNG or wood gas is dumped into the intake. But you can't have too high of a CR or working turbo charger for it to work.

It might be the case for most stationary applications, but what I have seen is resorting to CNG to replace part of the charge air, thus leading to a richer AFR which decreases the likelihood of knock. Then, even though the Diesel system won't be really idling, as it may have the same amount of injection cycles, the Diesel fuel flow is decreased accordingly to get the AFR closer to the usual.

Update: did a kilotank on 7.75 gallons

I like how this made the ecomodder newsletter.

Formula for avg of 180mpg to and from work: run battery in the morning and until range hits X on way home, then kick on hold mode, then drop back to electric at a certain point on my way home.
