Converting gasoline engines for use with biogas[edit source]
Regular gasoline engines can be converted for use with biogas, as these have spark plugs (diesel engines do not). Liquid-cooled engines are preferably since these allow to reuse the waste heat easily (considerable power herein -65% of power in the fuel-). To convert the gasoline engines, you could use the "Type 3 kits" of US Carburation, Inc (see http://www.propane-generators.com ). There are a lot of engines that can be converted using kits from there. I'm not sure whether you still need the T-joint and butterfly valve (see All Power Labs/GEK forums).
Note that the greenpower.cn biogas engine for example, and some others like the Honda GX160 are cheap engines which appearantly can immediatelly run on biogas yet are air-cooled engines. It may be possible however to use liquid-cooling on these aswell, by attaching a liquid circulation system on the plates conveying the heat to the air. It's similar to the water-cooling on motherboards/other boards in computers.
