Studies on alternative fuels have been active in Myanmar because the rapid mechanization of the agricultural sector demands higher diesel consumption. Jatropha oil-based biodiesel is one of the potential alternatives because of the relative ease of growing and producing this plant. In this study, both the experimental and theoretical analyses of Jatropha oil-based B20 biodiesel wereperformed and compared with conventional diesel. First, B20 was prepared by the base-catalyzed transesterification of the oil and its properties were measured. Second, separate performance tests were conducted on diesel and the biodiesel fuel using a LEYER-16 diesel engine. The speed range of interest was between 1000 r.p.m and 2000 r.p.m. Third, performance simulations were done in MATLAB using an algorithm written based on the theory of the engine operating cycle and air/ fuel compositions. Both experimental and simulation results show that there were no significant differences in the brake power and thermal efficiency of the engine between using diesel and the B20 diesel. However, fuel consumption when using B20 was slightly higher than that of diesel. This difference was marginal and it can be concluded that engine performance characteristics are the same for both diesel and B20 suggesting that B20 has great potential to be used as a substitute for diesel.

Fossil fuel crisis and depletion, environmental pollution and ever-increase in vehicle and transportation means have renewed the scientist’s interest in the world in order to look for potential alternative fuels, which are attractive such as biodiesel, bioethanol, DME and vegetable oils. Inedible vegetable oils such as coconut oil, Jatropha oil, linseed oil or animal fat are full of potential for using directly or manufacturing biodiesel. This work is carried out in order to study the four stroke diesel engine D240 performance characteristics fueled with preheated pure coconut oil (PCO), Jatropha oil methyl ester (JOME) and compare with diesel oil (DO). The test diesel engine performance such as power (Ne), torque (Me), specific fuel consumption (ge) and thermal efficiency (ηe) is determined, calculated and evaluated while using JOME, preheated PCO and compared to DO. The results show that, power (Ne), torque (Me) and thermal efficiency (ηe) while engine is fueled with JOME and PCO are lower, otherwise specific fuel consumption (ge) is higher than those of diesel fuel, the test engine performance are gained the best for JOME and PCO100.Article History: Received Dec 9, 2016; Received in revised form January 28, 2017; Accepted February 4, 2017; Available onlineHow to Cite This Article: Hoang, T.A and Le,V.

The use of fossil fuel is increasing drastically due to its consumption in all consumer activities. The utility of fossil fuel depleted its existence, degraded the environment and led to reduction in underground carbon resources. Hence the search for alternative fuels is paying attention for making sustainable development, energy conservation, efficiency and environmental preservation. The worldwide reduction of underground carbon resources can be substituted by the bio-fuels. The researchers around the world are finding the alternate fuel that should have the least impact on the environment degradation. This paper aims at finding an alternative for diesel and reducing the pressure on its existing demand. This study aimed at using two types of oil mixtures namely cashew nut shell oil and camphor oil mixed with diesel, turpentine oil mixed with diesel in different proportions as fuel in twin cylinder four stroke diesel engine. Performance and emission analysis have been performed by using exhaust gas analyzer in the oil samples. It was observed that 40% cashew nut shell oil and 10%camphor oil mixed with 50% diesel, 50% turpentine oil mixed with 50% diesel shows the better engine performance and also less emissions.

World at present is confronted with the twin crisis of fossil fuel depletion and environmental pollution. Rapid escalation in prices and hydrocarbon resources depletion has led us to look for alternative fuels, which can satisfy ever increasing demands of energy as well as protect the environment from noxious pollutants. In this direction an attempt has been made to study a biodiesel, namely Moringa Oil Methyl Esters [MOME]. All the experiments were carried out on a 4.4 kW naturally aspirated stationary direct injection diesel engine coupled with a dynamometer to determine the engine performance and emission analysis for MOME. It was observed that there was a reduction in HC, CO and PM emissions along with a substantial increase in NOx. MOME and its blends had slightly lower thermal efficiency than diesel oil.

Elastomer is one of the important material for the hoses, sealants and tubes in the components of fuel delivery system in diesel engine vehicles due to the factor of compatibility with diesel fuel. However, concern were arise that presence of alcohol, fatty acid component and other factors such as water content in the alternative fuels which is blended biodiesel fuel and different chemical composition from the diesel fuel may increase further uncertainty to the consumer of diesel engine or diesel engine manufacturers in terms of compatibility issue. Thus this paper intends to assess current and typical test standards on their efficacy of representing the fuel system of diesel engine vehicles. Respectively, ASTM D471 are based on laboratory immersion studies and the experimental conditions are differ from the real service conditions in the fuel system of diesel engine vehicles. Even though number of previous studies regarding to the compatibility of elastomer components has been reported, there is a need to set up the exact material that present in the fuel system of diesel engine vehicles. This is especially right for elastomers since their resistance is mainly depends on their elemental compositions. As such, introduction of the dynamic testing approach that may be applied when assessing the compatibility study between blended biodiesel fuel that simulate the actual fuel system of a diesel engine vehicles before carrying out in the field trials.

Production of alternative diesel fuel has been increasing drastically in many Asian countries. Since the reduction of petroleum production by Organization of Petroleum Exporting Countries (OPEC), the research on alternative fuel for diesel engine has gain interest. The target of this project is to substitute some percentage usage of conventional diesel fuel with waste substance without compromising on engine performance and exhaust emissions. This study has produced two type of alternative fuels. A test fuel consisting 30% of water into diesel fuel with the existence of additive or emulsifier (span 80) is called as DW Emul. Another test fuel which is named as DHW Emul produced by blending 30% of water into a mixture consisting of 20% of waste hydraulic oil and 80% of diesel fuel with the existence of span 80. The engine performance and exhaust emissions of DW Emul and DHW Emul are measured and has been compared with the conventional diesel fuel. A 600cc single cylinder direct injection diesel engine was used. The experiment was conducted at 1500 rpm with variable engine loads. Results show that DHW Emul and DW Emul has higher brake specific fuel consumption (BSFC). However, by considering the total use of diesel fuel contained in DW Emul, the quantity was lower at all loads. The same goes for DHW Emul at low load but deteriorate at high load which show slightly higher compared with of using 100% conventional diesel fuel. DHW Emul has suppressed CO emission that is usually high of using emulsion fuel to the level similar to conventional diesel fuel. NOx and Smoke emissions for DHW Emul are lower than conventional diesel. The use of DHW Emul can give significant reduction of NOx and Smoke emissions without deterioration of CO emission.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.

The purpose of this research is to perform comparative analysis of the effect of fuel additive SO‐2E on the economical and ecological parameters of a direct‐injection Diesel engine, operating on Diesel fuel and shale oil alternately. It was proved that multifunctional fuel additive SO‐2E applied in proportion 0,2 vol % is more effective for improving combustion of shale oil than Diesel fuel. At light operation range the treated shale oil savings based upon fuel energy content throughout wide speed range 1400–2000 min−1 reduce from 14,6–12,3MJ/kWh to 11,6–11,8 MJ/kWh or by 20,5–4,1 %. Maximum NO emission for treated Diesel fuel was reduced by 7,8–11,8 %, whereas NO2 simultaneously increased by 3,8–7,4 %. In the case of treated shale oil both harmful pollutants were reduced by 22,9–28,6 % and by 41,6–13,4 %, respectively. The exhaust gas opacity and CO emissions at the rated performance regime for both fuels were obtained a bit higher, whereas HC emission for treated shale oil increases 1,9 times and for Diesel fuel remains on the same level.
