Última PERFORMANCE OF DIESEL ENGINE FUELLED WITH FOUR VEGETABLE OILS, PREHEATED AND AT ENGINE WORKING TEMPERATURE REA Delalibera,Hevandro C.; Johann,André L.; Figueiredo,Paulo R. A. de; Toledo,Anderson de; Weirich Neto,Pedro H.; Ralisch,Ricardo. ABSTRACT With the rise of restrictions imposed by law for gases emission, several technologies both for petrodiesel (PD) or diesel engines are been applied, such as the sulfur reduction and the injection electronic command, followed of gases recirculation and/or after-treatment. The utilization of biofuels is considered as an interesting option for pollutants reduction. In this study was evaluated the performance on short duration tests (minor period than the factory indication of the lubricant lifespan) of the Diesel engine fueled with four vegetable oils. With the aim to select the most interesting oils for future evaluations in long duration tests. The analyzed variables were fuel consumption, power relative loss and opacity, for oils of linseed,...

Brazil is doing a major effort to find alternatives to diesel oil as combustible. Some study lines are oriented to the development of vegetable oils used as fuel, as a source of getting cheaper and have higher energy density than the converted vegetable oils, and less risk of environmental contamination. The aim of this study was to evaluate the performance, the useful life of the lubricant and some components of a Diesel Cycle engine, with an electronic injection system, in a long-term test operating with a preheated blend (65°C) of 50% (v v-1) of soybean oil in petrodiesel. There was a reduction of the useful life of the injectors which presented failure because of high wear with 264 hours of operation and showed an increase in emissions of particulate...

The study of spatial variability of soil and plants attributes, or precision agriculture, a technique that aims the rational use of natural resources, is expanding commercially in Brazil. Nevertheless, there is a lack of mathematical analysis that supports the correlation of these independent variables and their interactions with the productivity, identifying scientific standards technologically applicable. The aim of this study was to identify patterns of soil variability according to the eleven physical and seven chemical indicators in an agricultural area. It was used two multivariate techniques: the hierarchical cluster analysis (HCA) and the principal component analysis (PCA). According to the HCA, the area was divided into five management zones: zone... Tipo: Info:eu-repo/semantics/article Palavras-chave: Multivariate analysis; Precision agriculture; Spatial variability.

In Brazil, the best results in milk production are found in the state of Paraná. Such results are reached through genetic selection of the animals and management of their diets, in which whole plant corn silage is widely used. Aiming the silage quality, it was evaluated the influence of dry matter content of the corn culture as forage and the harvester adjustments on the fragment size of whole plant corn silage. The fragment size of two corn hybrids silage (SPEED and 2B688) was evaluated using a 5x3 factorial, with 4 repetitions. The first factor was the harvest time of the plants (105, 108, 112, 118, and 123 days after sowing (DAS)), which determines the forage dry matter (DM) content. The second factor was the harvester adjustments (2, 6.5 and 11mm of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Ensilage; Whole plant silage; Harvest time.

C.; Rocha,Carlos H.. Ao exigir áreas de Preservação Permanente (APP) e Reserva Legal (RL) em todos os imóveis rurais do Brasil, o Código Florestal Brasileiro (Lei Federal 4771/1965) se reverte em um dos instrumentos mais importantes com o propósito de mitigar impactos ambientais das atividades agrícolas. Como em outros estados, no Paraná esta legislação também foi ignorada; para cumprir o disposto no Código Florestal e estipular prazo para as adequações necessárias, foi instituído o Sistema de Manutenção, Recuperação e Proteção da Reserva Legal e Áreas de Preservação Permanente - SISLEG (Decreto Estadual 387/1999). Com o objetivo de se analisar essas normativas, elaborou-se um estudo de imóvel rural típico dos Campos Gerais do Paraná e, com base em técnicas de sensoriamento...
