Estudo e modelagem 3D de um cabeçote para um motor monocilíndrico, 400cc, 4 T

The cylinder head contains the combustion chamber for the air-fuel mixture and the intake and exhaust valves, the valve guide and the valve seat. The cylinder head also is a support for the camshaft and valve rocker. The holes where the spark plugs are connected are designed to fit the better place in the combustion chamber. The cylinder heads often are manufactured using materials such as aluminum and cast iron. The cooling fins located in the outside of the cylinder head are designed for a good heat transfer and therefore their dimensions and positioning are important. This work aims the calculation for a cylinder head to be installed in a 400 cc displacement, gasoline powered, four stroke, single cylinder engine. According to the displacement it will be analyzed the combustion chamber, the intake and exhaust valves, as well as the camshaft and rocker arms. This also a work to help to accomplish the design of a single cylinder engine, where the alternatives parts, cylinder block and crankcase are all already machined and assembled in this campus

Modelagem de motor de combustão internae simulação do processo de queima de combustível

The internal combustion engine is a heat engine widely used in the automotive industry. In order to better understand its behavior many models in the literature have been proposed in the last years. The 0-D thermodynamic model is a fairly simple tool but it is very useful to understand the phenomenon of combustion inside the chamber of internal combustion engines. In the first phase of this work, an extensive literature review was made in order to get information about this kind of analysis and, after this, apply them in a model able to calculate the instantaneous temperature and pressure in one zone of the combustion chamber of a diesel engine. Therefore some considerations were made with the aim of increasing the accuracy of the model in predicting the correct behavior of the engine, adding the combined effects of heat transfer, leakage and injection. In the second phase, the goal was to study the internal flow of a three-dimensional model of an internal combustion engine. In order to achieve this goal the software Solidworks was used to create the geometries of an engine and the suite of softwares Ansys was used to create the moving mesh (ICEM CFD and CFX-Pre) and to solve the CFD problem (Ansys CFX code). The model was able to perform the air flow simulation during the four-stroke cycle of an engine: admission, compression, expansion and exhaust. The results obtained from both models were suitable and they open a new range of possibilities for future researches on the field

Obtenção de compósitos nanoestruturados PSU/nanotubos de carbono pela técnica de eletrofiação

The nanostructured materials over the last decade have been increasing the variety of studies and research applications in many industries. From the understanding and manipulation of nanoscale is possible to obtain high-performance materials. One method, which has been very effective in obtaining of nanostructured composites, is the electrospinning, a technique that uses electrostatic forces to produce fibers from a polymer solution. By understanding and controlling of process conditions, such as solution viscosity, working distance, the velocity of the collector, applied voltage and others conditions, it is possible to obtain fibers in many different morphologies. This work aims to obtain nanostructured composites from polysulfone (PSU) a thermoplastic polymer with high oxidation resistance and good mechanical strength at high temperatures and carbon nanotubes (CNTs) that are excellent reinforcements for polymer materials, their mechanical resistance is greater than that of all known materials; using the electrospinning process via polymer solution. Were used polysulfone solutions, n,n-ndimetil acetamide (PSU / DMAc) and this same solution added of CNTs in order to obtain the nanofibers. In both cases were analyzed the effectiveness of the process from the analysis of fiber diameters, rheological behavior and infrared spectroscopy. The results obtained confirmed the efficiency of the electrospinning process to obtain polymeric fibers
