| Abstract: | The current valve design found in modern four-stroke internal combustion engines
employs poppet style valves for fresh air/fuel mixture admission to the combustion
chamber, as well as the relief of burnt gases away from the cylinder. These valves are
relatively simple in design and their lifetime is approximately equal to the life span of the
entire engine. Current valves, however, cause intake and exhaust obstruction, thus
reducing the overall efficiency. In addition, the excessive number of parts involved in a
typical valve-train cause friction, which lead to reduction in net power output. Our
objective is to redesign the engine intake/exhaust system in a way that we can eliminate
most of the auxiliary parts of the valve-train. In doing so, we plan to replace the poppet
style valves with a screw form that will rotate. This rotation will create forced flow to
and from the combustion chamber, thus increasing efficiency. For the purposes of this
design, we intend to modify the valve seats of an existing engine head to a design of a
rotary type valve. Through our design project, we will model a new design and create a
prototype. We will also compare our theoretical efficiencies to those of the existing
poppet valve design. |
