my.unimap-221862012-12-09T08:31:19Z Design and manufacturing process of rotary valve for internal combustion engine Meera, Vajaindran Prof. Dr. Ryspek Usubamatov Rotary-valve Internal combustion engine Automotive industry Access is limited to UniMAP community. A rotary valve system is capable of controlling intake and exhaust gases, which will eliminate the need of well known complex mechanism with camshafts, poppet valves, etc, and reduces the number of moving intricate parts in a cylinder head. The cost of material and production, component wear rate, and noise level of the system can be further reduced. The new mechanism enables the elimination of the overlapping of valves work like earlier opening of valves and late closing that reduces gas leakage. This project examines theoretically the gas flow through the holes of a rotary valve design in an internal combustion engine. Initial findings from fluid dynamics calculations indicate that the new system leads to increasing the efficiency and reliability of the gas intake and exhaust mechanism performance. Results from the gas flow calculations show that the speed of gas flow in the new system has many differences than conventional camshaftpoppet- valve system. Calculations indicate that the change of the volumetric efficiency of an engine, discharge flow coefficient, and dependence on the gas speed enable the finding of better solutions for the geometry of a rotary valve. These positive attributes of the new rotary valve system will result in a higher efficiency of an internal combustion engine and the mechanism will find wide application in the automotive industry. 2012-12-09T08:31:19Z 2012-12-09T08:31:19Z 2009-05 Learning Object http://hdl.handle.net/123456789/22186 en Universiti Malaysia Perlis School of Manufacturing Engineering |
