2. PERFORMANCE OF DIESEL ENGINE FUELLED WITH FOUR VEGETABLE OILS, PREHEATED AND AT ENGINE WORKING TEMPERATURE
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 pollutant

3. REMOVAL OF WATER CONTENT FROM BIODIESEL AND DIESEL FUEL USING HYDROGEL ADSORBENTS
Abstract The removal of water content present in fuels such as biodiesel and diesel is quite important to adequate the fuel to standards for commercialization and to avoid corrosion of storage tanks and injection equipment in diesel engines. In this study, hydrophilic hydrogels were employed to remove the water content in biodiesel and diesel fuel samples. T

4. Effect of desulfurization of diesel and its blends with biodiesel on metallic contact
The current environmental scenario has required changes in fuel nature, in order to minimize the harmful effects caused by sulfur in diesel. However, reductions in sulfur content promote loss of its lubricity and consequently wear in the injection system of the diesel engine. This study aimed to investigate the influence of sulfur minimization on fuel lubric

5. Micro and nanometric wear evaluation of metal discs used on determination of biodiesel fuel lubricity
The contact of diesel fuel with engine subsystems demands a good wear resistance. Lubricity is an important feature for integrity of injection system and the sulphur composites are primarily responsible for lubrication of the injector nozzle. Biodiesel is responsible for partially restoring the lubricity of diesel fuel that presents low levels of sulphur com

6. Determinação eletroquímica de glicerol em biodiesel por amperometria de múltiplos pulsos com eletrodo de ouro
Biodiesel is the fuel obtained from vegetable oils or animal fats that can partially or totally replace diesel oil. Besides being obtained from renewable sources, biodiesel is less polluting than diesel and biodegradable. One disadvantage of biodiesel is the byproduct of transesterification reaction of raw material, glycerol, which can cause damages to combu

7. Optimization of diesel engine parameters using Taguchi method and design of evolution
The objective of this work is to optimize the control parameters of the direct injection (DI) single cylinder diesel engine with respect to NOx (Oxides of Nitrogen) and fuel emissions through experimental investigations and Taguchi method. A single cylinder 5.2 kW diesel engine was selected for this experiment. Five parameters such as clearance volume, valve

8. Análise de falhas em tubos sem costura de aço St52 utilizados em motores diesel / Failure analysis in seamless pipes of St52 steel used in Diesel Engines
The carbon steel with high manganese in accordance with Din 1.0580 (St52) seamless 8 x 3 mm diameter has been used into fuel injection system of the electronic diesel king with pressure up to 1300 bar. This tube presented short life on durability tests due to inner cracks created during rolling process. The tube produced in Brazil and used nowadays in was co

9. Remediation of soils contaminated by diesel fuel using a system of washing with microemulsion / Remediação de solos contaminados com óleo diesel utilizando um sistema de lavagem com microemulsão
The underground reservoirs of fuel retailing system represent an environmental threat, because once in bad conservation, these tanks allow fuel leakage and infiltration. For soil contaminated with fuel, such as diesel oil, the present study introduces the microemulsion systems used by the method of washing. In tests carried out in column with a sample of san

12. Performance and gaseous emissions characteristics of a natural gas/diesel dual fuel turbocharged and aftercooled engine
The aim of this paper is to investigate the performance and emissions characteristics of a turbocharged and aftercooled diesel engine operated with natural gas as primary fuel, and diesel fuel as ignition source. In such dual fuel operation, much of the energy released comes from the combustion of the gaseous fuel, while only a small amount of diesel fuel pr
