摘要: A Brownian microscopic heat engine with a particle hopping on one-dimensional lattice driven by discrete and periodic temperature field in sawtooth potential is investigated. In order to clarify the underlying physical pictures of engine, flow via energy kinetic particles are considered simultaneously. Based describing jumps among three states, expressions efficiency power output derived analytically. The general performance characteristic curves plotted numerical calculation. It found that output-efficiency curve loop-shaped one, which similar one for real irreversible engine. influence ratio hot cold reservoirs maximum analyzed some given parameters. When flows neglected, an open-shaped endroeversible
