I did not try to run it on 100% natural gas as i am sure it will not ignite the natural gas only. That is why i run a small amount of diesel for ignition purpurposes. You would not want to add a glow plug as this would iginite the mixture in the intake tract when the intake valve is open. you could add spark ignition and some have but i like using the diesel for pilot ignition and when additional fuel is needed. in my setup the original governor is not changed or modified in any way
I understand the compression will not ignite the natural gas alone. Have you found this to be true when attempting to run 100% natural gas? Would a glow plug allow the engine to function with NG? Or just add a spark plug. I still has the high compression and thus efficiency!
Thanks for the quick reply. I only have small cylinder of methane and cannot do long trials before making decision spark or no! after that its connect to our digester. Can you tell me diesel usage with and without gas. i need to find what % of diesel can be minimum used to give spark. Trying to balance cost of diesel against hassle of trying to get a spark. Any long term effects running this way?
This is exactly what i have been trying to do with a listeroid 8/1 but using methane .
I havent got as far as you just established that when you add methane govenor soon shuts down. If you published results could you point me to them please. our original intention was spark ignition but it would be much easier to stay with some diesel , i am trying to do some measurements but i have not got setup as good as yours yet. Thanks
I use a small needle valve to control the amount of natural gas that is feed into the engine. Trying to open the valve too wide will cause the governor to close the fuel rack completely and the engine will shut off because it needs a small amount of diesel to stay running. I marked the injector plunger with a scribe with the engine at an idle under no load. I then put the engine under a 2,000 load and started to slowly introduce the natural gas as i watched the fuel close.
I stop adding natural gas when the rack/plunger is back to the point where i scribed the line at a no load idle. While this is not an ideal situation most of my needs are in the 2,000 watt area. For me this is a simple setup and the engine has not been altered in any way. You may need to make a slight adjustment to the governor spring but that is no big deal.
Hi. Can you please tell me why the gas does not flow up and out of the Air filter? It seems like it would.
Is it because there is constant suction from the engine? If it is, then the pressure regulation of gas would be critical. Am I right or is there something else?
Since this engine does not have a spark plug it would have to be modified with an ignition system to burn either fuel straight. I only use a very small amount of diesel to start the combustion process which is metered by the governor. This is the simplest way to do it and still retain the ability to run on straight diesel should I so chose.
I am extremely interested in getting these test results, as I am about to repeat the same tests, for my own use. I do have a lister for heat and additional electric. I am burning diesel fuel currently and plan to use WVO. The natural gas data is needed to avoid some coking problems that I anticipate having with the alternative fuel.
Thank you for sharing your efforts, research, and information. I have been thinking how to implement NG and the standard Combination Gas Valve is a great solution.

@gpety
when running natural gas the ratio is about 75% gas 25% diesel. Under 2,000 watt load it uses about 1 liter an hour when on Diesel only.

@hotrod3737
very cool setup. What was your diesel consumption/hr when using 75% natural gas?
I like your safety solenoid setup too. very clever.

Like the air start, could you give me some idea what this engine alone cost? Did you buy it direct from India? Great job, btw

$500 bucks sitting on a the dock in Mumbia.....
Shipped to you??????
More....
Expect as much as 1500 in handling costs.
Been there done that.
Talk to an import broker before you pay any money out.

I was curious if you have the data with how much fuel your lister takes per hour?

what about straight natural gas or woodgas
