You can run a diesel engine on woodgas. But... you must either use about 15% diesel (adding the woodgas like you would propane) or add a spark plug instead of an injector. It's much like running a diesel on methane or landfill gas.
The challenge is filtration. Like kerrynzl said, there is a real tendency to gunk up your engine with soot. However, I've worked with over half a dozen different gasifiers and all but a couple of them have been downdraft style, not updraft and downdraft at the same time or using two together. And, the overall process is not endothermic. There are a bunch of chemical reactions going on within a gasifier... like a thermochemical symphony. Overall, a gasifier will generate more heat than it consumes. We're talking about a process that runs at about 1650 degrees F.
Ultimately, I want to use gasification to run a generator and congenerate heat for process applications.
I just bought a '95 F-150 with a 300 six as a test mule. First, I want to see what it takes to run 100% ethanol (no gasoline at all) and later to run it on woodgas. No question of "if" but more about "how well". Bump the compression, change the timing and most important of all... filtration!
To put it into perspective, woodgas typically has about 10% of the BTU as propane.
