Basic Studies on Stirling Engine Using Combustion Heat of Biomass (Part 2)

Output Power of Power Bellows Type Model

Abstract

Leakage of working fluid from a Stirling engine system is a serious problem. Instead of a power piston, a stainless steel bellows element was applied to a trial-made engine for its power actuator to prevent gas leakage and to decrease friction losses at sealing.
This report described output power performance of the bellows type Stirling engine model and the effects of bellows actuator were discussed. Its indicated power was more than two times as that of the piston type model producing about ten watts of net power.
