Convert your Honda Accord to run on trash

Step 4 History, Theory and Overview

See here for basic information on wood gas and biomass gasification.

The GEK gasifier design is based on a nozzle and constriction (Imbert type) downdraft reactor. This was the typical gasifier reactor type of WWII, and still the usual starting point for generating low tar wood gas to power internal combustion engines. The GEK design combines all common Imbert type variations into a single configurable reactor, with easy adjustability of all critical dimensions. Gasifier geeks will swoon to know that it supports:

• variable combustion / reduction zone size and shape (tube, bell, inverted V, hourglass)
• variable air nozzle position and size
• air preheating (or lack there of)
• active tar recycling into incoming air
• variable air injection architecture (air from top, bottom, or side annular ring)
• "monorator" type condensing hopper
• rotary grates/stirrer additions

The GEK Imbert reactor standard sizing and configuration is known to produce clean syngas when operated by a knowledgeable enthusiast. This default configuration will run 5-20hp engines. We've expanded the internal sizes for the Honda Accord project so it can support the 70HP or so Honda engine.
