2 more interesting articles, when you decide to modify things:
and for the die hards: about the squish action from your pistons

That is a very interesting writeup on coal gas. I find the blue gas process they discribed most interesting. Here is the water gas entry.
The thing I wounder about after reading this is getting a bottle of oxygen and use that as the air supply for the gasificer? It looks to me in the coal gas write up this would result in a much more power dense fuel and maybe get some of the lost power back when running wood gas. Seems like it would be relatively easy to test. The setup would be a little tricky because you wouldn’t want the oxygen to leak onto anything that might burn. That would be way more excitement then any of us would want.
Just something to think about. It is really way over my head but I found it interesting.

Hi Dan,
use a oxygen separator would help a lot to produce “better” gas but still, the gain is not as big as if you would increase the intake efficiency from your engine ( Valve timing, valve lift, larger intake , the works ) and increasing the CR from your set.
The bottle of oxygen does however give fun moments in experimenting… Allows to induce more exhaust gasses or waterdrip…

Now, this guy’s are going to receive some product orders from me if i can… 
Nice article and nice products on their website…

That is a well written and very clear explanation of the spark ignited combustion process
Thank you for posting it

Been on the road for about 3000 miles now…
Its a beast, not a pussy…
driving on pure charcoal gas:
Doing some long hills climbing (8%) average 12,6 Kg Charcoal per 100 Km, with the flats ofcourse…
The engines bites itself @ 3000 RPM and the gearing is superb in the range 2500 to 3500
Revving up to 3300 without hesitation Torquing from 2300 do able
The steeper the hill, the wiser to choose the correct gear, but still … thinking and feeling more power from Charcoal gas then from CNG
Its all about the correct fuel trim i guess
The car loves long stretches on charcoal, no need for hybrid driving.
Short start stops, more consumption average from CNG, it looks that the engine is build for long steady instead of city traffic.
Everybody happy… the beast not tamed yet…
Oh yeah, guess what… the wife found the “knock sensor”
my old eyes i guess…

Hi Koen, can you post a driving video? I think several folks would like to see this truck in action.

Uploading some clips now, here is two… coming more but taking ages… don’t mind the timestamp, i forgot to adjust before making the clips…

Thanks for the ride Koen. Was that on charcoal or petrol? Hard to tell because it ran so good. You sure have a lot of fences and walls around property over there on the second video!

Hi Don,
No petrol on board… startup on CNG with autoignition, switchover in less then 2 minutes ( cold state) to Charcoal and in less then 20 seconds when warm.
Engine run’s great and compared with CNG it feels equal.
Still tweeking around with the mapping, but getting at the point that it does not need improvement…
I sized nozzle and performance of the gasifier to the average energy consumption for the Tata , not for max HP, so i need to adjust my driving. ( Actually i adjusted the gasifier to my driving style )
Torque in lower RPM could be better but it runs great…
I can adjust the ECU settings “on the fly” with the Tablet left side ( not really on the fly but you get the point )
Edit: being this a testing unit… i start every drive / day with a cleaned gasifier…/ fresh charcoal…

uploading some clips from my phone to, shaking but more detail of the dashboard…
one more actioncam…

Looking good Koen! I don’t see you fiddling with controls or checking gauges. Do you monitor temp or vacuum on the gasifier?
Like Don said, you hardly would know it’s on charcoal gas!

Hi Chris,
1: Automatic air-gas mix valve, base adjusted, AFR compensated
2: No temperature controls / vacuum-gauges yet
ECU retuned and remapped
Auto CNG reduction with AFR, adjustable in programming 0% to 100% in both directions
Knock sensor adjusted ignition mapping
and the high CFR…
also slightly modified cam timing / cam lift
On video it looks “perfect” but its still tuning tuning tuning… ( lovin it )
You’l need to come over and “feel” it, but then you probably would build a charcoal set when you return ?
I am pretty sure that when i try a WK in USA i would start building one here…

Good morning Koen.
Thanks very much for the videos 
I enjoyed watching but I would probably kill myself driving on the wrong side of the road …
The little truck does great!!

No no Wayne he is driving on the correct side of the road !
Nice one Koen , looks and sounds pretty good , do you have any pictures of your nozzle set up and what size nozzle did you go with .

Hi Wayne,
Yeah, wrong side of the road… still wearing the collar from last time
It does look little, but the bed is 8ft long 6 ft wide…
compared with the TukTuk daihatsu, its huge

Hi Dave,
Still using the similar nozzle setup ( horizontal with elbow pointing up nozzle tip )
Sizing at this moment 32 mm
Still trying to find time to do / to test many modifications
Will post pictures soon…
