Abstract

This involves a project which went through a long initial phase of development as proof of concept, in which two engineering models were studied which demonstrated excellent qualitative results. The engine is a technological innovation, presenting a low weight/power relationship associated with a high torque. It possesses four combustion chambers in the form of cylindrical sectors delimited by four juxtaposed and rotating pistons which execute a non uniform movement between them, permitting admission, compression and escape. Each rotation of the set of 4 chambers/4 pistons, permits a sequence of four explosions. The present phase of the project proposes to develop and manufacture a working prototype in order to obtain quantitative results with a view to its qualification, industrialization and commercialization. The work will be divided in four stages: design, manufacture and assembly, tests in bench trials and verification of performance. (AU)
