Technical Paper


This paper presents an Atkinson Cycle mechanisms classification. The proposed classification is based on mechanism theory, dividing the mechanisms into two main classes and eight subclasses. The reconfigurability of Atkinson Cycle mechanisms is discussed as well as the mechanism characteristics for each class. This classification was applied to the engines found in bibliography and patent survey. Both surveys were necessary to yield a complete state of the art, regarding not only academic but also technological advances. These surveys and the Atkinson Cycle engine classification expose the wide window of opportunities for engine development. The use of reconfigurable Atkinson Cycle engines can be a powerful tool to develop more efficient vehicles.
