Cogeração de energia com motores de combustão interna

The tertiary sector is largely responsible for the growth of electricity consumption in Brazil. The large commercial and public buildings, hypermarkets and shopping centers stand out as major consumers of electricity for lighting, power and thermal energy. Brazil presents significant potential for the deployment of small cogeneration plants, especially in the tertiary sector. Allied to this, the possibility of natural gas supply and the growing demands in favor of maintaining and preserving the environment favor the implementation of cogeneration plants. In this context, this paper presents a technical and economic analysis of installing a cogeneration plant using internal combustion engine with natural gas in a mall

Proteção de motores elétricos de grande porte

Large electric motors require greater care when driving, especially during continuous operation since they are part of day-to-day manufacturing sector, acting essentially to ensure that no damage occurs to the production process and equipment that are part of the same system. This work includes the analysis of electrical protection in a system comprised of a three phase induction motor driven by a frequency converter as well as an analysis of the functions of a multifunction electronic relay. It is presented a comparison between the existing functions in a converter and a relay and a real case is described in order to exemplify the use of an electric motor and features that are aimed at their protection, and the system in which it is inserted. Based on the results, it is of great importance in this field of performance studies, generating relevant results, which may be exposed in order to unify into a single document, different sources of information that are arranged randomly, improve utilization motor and extend the life of equipment forming part of the electrical installation

Estudo da modificação do ângulo do conjunto cilindro-pistão em motores de combustão interna

The aim of this study is to present those who are interested in mechanical engineering, specifically automotive engineering some ideas for improvements to the current concept of internal combustion engines. It is not intenden to change totally the design of the engine known today, but to exame the feasibility of reducing a small waste generated with the current positioning of the cylinder-piston assembly. The proposal solution consists in modifying the tilt cylinder-piston assembly in the angle between the rod and the cylinder axis. This inclination causes all the force generated in the combustion process within the cylinder is delivered to the rod.Delivery force is the made in the rod longitudinal direction and not on the axis of the cylinder, preventing the occurrence of a breakdown of the force generated in the combustion process. After analyzing the idea of repositioning the piston-cylinder assemble, it is concluded that the change has a positive result in the process of harnessing the power generated in the com bustion, but its not feasible due implementation to low gain presented in this study

Análise do gerenciamento de projetos de produtos na área de desenvolvimento de motores em uma indústria automotiva

L'un des facteurs nécessaires pour qu’une entreprise reste compétitive sur le marché est la création ou l'amélioration d'un produit afin qu’il réponde aux besoins et aux attentes des clients, ainsi, le Processus de Développement de Produits (PDP) est essentiel. Pour la réussite du PDP, il est souhaitable de suivre un système standard de gestion de projet. L'objectif de cette étude est d'analyser la gestion de projets dans le processus de développement de produits dans l'industrie automobile afin d'identifier les possibilités d’amélioration. Par conséquent, nous avons procédé à une revue de littérature sur le sujet, analysé les lignes directrices et les pratiques du processus de développement de produit dans l’entreprise. Comme résultat, il a été obtenu que le système de développement de produits créé par l’entreprise requiert la clarification des outils utiles à la gestion de projet. Un problème de communication et de gestion des coûts a également été constaté dans le domaine du développement du moteur lourd

Analise de defeitos em motores através de vibração mecânica: estudo de caso

Revolving machines are among the most used equipment in general industry and therefore expenditures on this equipment class are a significant portion of the total amount spent by the company. If there is an unscheduled stop of some of this equipment, industrial plants can lose huge amounts of money caused by interrupted production and parts delay. Others may increase significantly maintenance costs due to consequences elsewhere not affected before. Even plant and people safety can be in danger if there is an operation interruption without a backup system start. This work is focused on a rotating system case study which is monitored by vibration analysis that shows that is possible to determine when is the most appropriate time for equipment intervention without any reliability loss just by using a simple and cheap system which is not much used because professionals are not aware to its utility. Industrial facilities were evaluated by fail detection and historical analysis in some equipment in order to show feasibility of vibration analysis through a before-during-after process. The plant evaluated is part of a chemical multinational located in Guaratinguetá-SP. At this time, that plant had around 650 critical equipment monthly monitored and no unscheduled shutdown was registered in one year period due to equipment monitoring

Letramentos acadêmicos e multimodalidade em contexto de EaD semipresencial

From a theorethical enunciative-discursive perspective, this article aims at discussing the process of the text consistency in digital context, in a particular manner, by means of problematic semiotic modes and resources updated in the academic production of the student who uses internet access computers in the semi-present Distant Learning (DL) process. It’s of interest to investigate how the academic literacies model may be linked to the multimodality study, considering, in theory, that in an electronic environment, the student has “unlimited” access to every and any kind of text, not just the “verbal” (name generally attributed to the graphic component) one. The collected material contains texts which were produced by the semi-present Pedagogy Course students from the Virtual University of São Paulo (UNIVESP), in 2010.

Letramentos acadêmicos no ensino superior: aspectos verbo-visuais no processo de textualização em contexto semipresencial

Este trabalho situa-se na discussão sobre escrita na universidade e investiga o processo de textualização verbo-visual e extraverbal em contexto de Educação a Distância (EaD) semipresencial. Com base no conceito de letramentos acadêmicos, advindo dos Novos Estudos de Letramento, busca problematizar relação entre cor escolhida e imagem, no processo de produção do texto realizado por universitários (professores em formação), num Curso de Pedagogia semipresencial de uma universidade pública do Estado de São Paulo. Procura, assim, contribuir com os estudos da linguagem no que se refere ao estabelecimento de critérios para investigação da integração entre semioses diversas na constituição de conceito de “texto” não restrito ao reconhecimento de sua base gráfica.
