Abstract
Since fossil fuels such as petroleum, coal, and natural gas are limited resources, renewable energy such as solar, wind, and biomass will be needed as substitute fuels. A new type of engine system that uses biomass fuel such as sawdust and rice husk was proposed in this report. A Stirling engine, an external combustion engine, is introduced. The pistons are moved by heating and cooling air in the cylinder. A burner using the biomass fuel heats the air in the expansion room to about 650℃ and a cooling system cools the air in the compression room to about 60℃. The cylinder motion revolves the crankshaft at a rate of 650rpm. The new engine features a traction force of 5HP and a power generation efficiency of 3kW.
