Pope's design included an ingenious way to add variable amounts of steam 
into the reactions zone to control temperature. Here's a link to a page 
that describes his design

You also have choices of either wood or charcoal gasifiers the preferred choice for mobile use in Australia and New Zealand from the early days of engine powered machinery until the end of WW2.

You can cut it green, but bounce an axe off it when dry. It make absolutely the best quality charcoal money can buy or make yourself, that is if you can find a place not protected from native tree removal. Don't become an environmental terrorist, or arsonist to make your fuel.

If there were a compact gasifer design which could be mounted on a tow bar or a bracket on a caravan, it could be real money spinner if the transport authorities allowed its use.  But how small can a gasifer be made that while being able to supply enough gas to run a 3 litre engine?
