dc.description.abstract The internal combustion engine, performing mechanical work by harnessing combustion, has proved to be a convenient, efficient and reliable path in the last decades. However, the complexity of the inner structures and mechanisms act as the essential barrier which limits the further improvement of the internal combustion engine. The valve train, the structure that operates the combination gas exchange, contributes its friction to the internal mechanism loss which consumes power and confines the thermal efficiency. Based on the shape and operation of conventional poppet valves, a manufacturer has to sacrifice the piston top design and compression ratio to prevent valve-piston interference.
dc.description.abstract This innovational research focuses on not only the valve train structure and driving method but also the shape and operating condition of the valve itself. As a new valve design, a unique Erect Located Cone Rotary Valve will be spinning inside of the combustion chamber to operate combination gas exchange.
dc.description.abstract The thesis introduces the history of the internal combustion engine and the classification of the valve configuration. The research exposes the problems of the conventional poppet valve and discusses the advantages and limitations of previous rotary valve designs. The thesis presents detailed analysis, calculation and parameters of the erect rotary valve and also describes the limitation and the compromise of the current erect rotary valve design. In the end, the research provides the feasibility and direction of future development. M.S.
