6/1 Listeroid Natural Gas / Diesel

This is my 6/1 setup for use with both natural gas & Diesel or diesel only.

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

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?

thanks again

@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.

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.

@hotrod3737

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.

very cool setup. What was your diesel consumption/hr when using 75% natural gas?

I like your safety solenoid setup too. very clever.

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!

nice job I have a Lister as well would like to try this.

nice job

Cheers .  Will try and get Methane Listeroid posted in due course.
