Atkinsontsükkel

Atkinsontsükkel refers to a theoretical thermodynamic cycle proposed by John Atkinson. It is a closed thermodynamic cycle that aims to improve the efficiency of heat engines. The cycle is characterized by a specific sequence of thermodynamic processes involving heat addition, expansion, heat rejection, and compression. Unlike simpler cycles, the Atkinsontsükkel often incorporates elements such as isochoric (constant volume) or isobaric (constant pressure) processes for heat transfer, aiming to achieve higher theoretical efficiencies by prolonging the period of heat addition or rejection. The practical implementation of engines based on the Atkinsontsükkel can be complex, often requiring specialized valve timing or variable valve actuation mechanisms to achieve the desired process sequencing. While the theoretical efficiency of the Atkinsontsükkel can be attractive, its real-world advantages and disadvantages are subject to engineering challenges related to cost, complexity, and performance across a range of operating conditions. Engineers may consider the Atkinsontsükkel when seeking to optimize specific performance metrics, such as brake specific fuel consumption or power output, within the constraints of a particular application.
