Following an intensive 2 day gasification workshop at All Power Labs, an Indian 6hp Listeroid has run successfully at full power on woodgas as the result of a simple spark ignition conversion.

Mike Anthony, Ken Boak, Jay Hasty, Jim Mason and William Steele, aided by GEK workshop attendees and the staff of All Power Labs, got the engine running on 100% woodgas after an 8 hour conversion process.

The conversion uses a Hall effect sensor detecting a magnet fitted to the flywheel. An Arduino microcontroller board detects the output of the Hall sensor as the magnet passes just before TDC. The Arduino initiates the firing of a spark plug with multiple spark burst and variable ignition timing.

The woodgas conversion utilised a custom manufactured woodgas carburettor made by Andy Schofield.

The woodgas was supplied by the newly launched V4 GEK, put together by Jay Hasty aided by Opalyn Brenger and Walt Patrick from the Windward Foundation.

The standard 6hp Listeroid engine was belt driving a 5kW ST alternator head. Electrical load tests revealed that 2.75kW power was easily obtainable from the alternator, suggesting very little de-rating of the engine output when run on woodgas.

The plans for this spark ignition conversion will be available soon as an open source resource through All Power Labs. A kit for the woodgas carburettor and spark conversion may be released independently. This will allow existing Listeroid users to benefit from wood gasification directly without the need to run a dual fuel system.

More video of the conversion process will be released shortly from All Power Labs via YouTube. .
