[Gasification] Lister on Gasoline, ingition control device?

[Pete & Sheri]

Hello, Ken.

  Did you ever publish the circuit for your ignition control device?  I seem
to remember seeing a video that showed it in action.  Looked like maybe
there was an Arduino in there somewhere.

Alex,

 

We* found that the Lister had to be significantly advanced when running on
woodgas in spark ignition mode.

 

It was anticipated that we might have to be 20 degrees BTDC, but when the
engine was finally running well, it was found to be around 57 degrees BTDC.


 

The Lister has a 24" diameter flywheel, thus a 75.4" circumference. Our
optimum ignition point was found to be 12" on the rim ahead of the TDC
position.

 

The Lister rpm was limited to 600rpm because of an undesirable resonance
around 610rpm - a quirk of the specific engine we were using at APL.
Normally the 6hp Lister should rev to 650rpm without vibration.

 

Marcus Hardwick and I wrote up most of the technical detail here

We* - the Lister team at the April APL workshop consisted of Ron Ohler, Andy
Schofield, Marcus Hardwick, myself and contributions from other workshop
delegates.
