11Th International Scientific Conference Engineering For Rural Development Jelgava Latvia 24 25 May 2012, 2012

Due to global warming during the recent years the average temperature of the world has essentially increased. The main reason for the global warming is carbon dioxide, and motor vehicles are one of the main emitters of CO 2. Considering different arguments on adaptation of engines of transport vehicles for operation with different fuels it can be concluded that it would be more rational to create cheap fuel that could be used in the already existing transport vehicles with minor modifications. Rapeseed oil in the conditions of Latvia is the most economically efficient; it belongs to the fuel group of the first generation and it is certified by law in Latvia. It is allowed to be used in diesel engines having regard to the determined emission requirements. One of the branches where rapeseed oil can be used as fuel is agriculture. In land cultivation high power machinery is used and it is operated for a long time with high load so creating a considerable amount of exhaust gasses. Usually such machinery has no catalytic converters that help decrease the amount of the toxic emissions. Using rapeseed oil as fuel in motor vehicles for land cultivation that is mainly done in summer there is no need to worry about the rapeseed oil viscosity, but as the number of investigations is rather small, additional research is needed in the content of the rapeseed oil fuel emissions. Therefore, an experiment was made on the changes of the composition of the exhaust gases using rapeseed oil as fuel and its blends with fossil diesel fuel. In the research it was stated that rapeseed oil 50 % blend with fossil diesel fuel was the most optimal as at average revolutions the emission of CO 2 is comparatively the smallest, the amount of NO x and SO 2 is decreased using all blends but the amount of CO, mechanical particles and unburned hydrocarbons is approximately the same in the emissions for all fuel samples.

The idea that has conditioning this paper was the use of biofuel based on rapeseed oil on a medium-power diesel engine, alternative power supply being used, both as with diesel fuel and with rapeseed oil mixed with diesel in various proportions. This paper presents experimental results on a diesel engine effective power and torque performance of fueled with fuels based on rapeseed oil compared with diesel fuel. Fuels used in experimental research were mixtures of rapeseed oil, rapeseed methyl ester and diesel in different proportions: 80% diesel fuel -20% rapeseed oil, 50% diesel fuel -50% rapeseed oil, 25%diesel fuel -75 % rapeseed oil, 100% rapeseed oil, 100% rapeseed methyl ester (RME) and 100% diesel fuel as (reference fuel). Because the researches were focused on the use of fuels derived from rapeseed oil on the existing Romanian engines, the work initially focused on those factors that do not involve changes or adjustments to diesel engine. International researches conducted s...

In the recent past, intensive studies on internal combustion engines has emerged with a view to obtaining higher rate of production of fuels from alternative sources. The increase in alternative fuel investigations is caused by two main factors; a rapid decrease in world petroleum reserves and important environmental concerns originating from exhaust emissions. Fast depletion of the viable alternative fuels. Diesel fuel is largely consumed by the transportation sector. Thermodynamic tests based on the engine performance evaluations have established the feasibility of using vegetable oils. It has been found that vegetable oils hold special promise in this regard, because they can be produced from the plants grown in rural areas. Vegetable oils from crops such as soya bean, peanut, sunflower, rape, palm, coconut, karanja, neem, cotton, mustard, jatropha, linseed and caster have been evaluated in many parts of the world in comparison with other non-edible oils. To solve energy and envi...

Publication Impact Factor (PIF):1.026 www.sretechjournal.org Abstract In view of increasing pressure on crude oil reserves and environmental degradation as an outcome, fuels like Ethanol blended with Rape seed oil may present a sustainable solution as it can be produced from a wide range of carbon based feedstock. The present investigation evaluates Ethanol blended with Rape seed oil as a diesel engine fuel. The objectives of this paper is to analyze the fuel consumption and the emission characteristic of a twin cylinder diesel engine that are using Ethanol blended with Rape seed oil& compared to usage of ordinary diesel that are available in the market. A four stroke Twin cylinder diesel engine was adopted to study the brake thermal efficiency, brake specific energy consumption, and emissions at zero load & full load with the fuel of methanol. In this study, the diesel engine was tested using Ethanol blended with Rape seed oil. By the end of the experiment, the successful of the experiment have been started which is Diesel engine is able to run with Ethanol blended with Rape seed oil but the engine needs to run by using diesel fuel first, then followed by Ethanol blended with Rape seed oil and finished with diesel fuel as the last fuel usage before the engine turned off. The performance of the engine using Ethanol blended with Rape seed oil fuel compared to the performance of engine with diesel fuel. Experimental results ofEthanol blended with Rape seed oiland Diesel fuel are also compared.

To solve energy and environmental concerns, the renewable energy with lower environmental pollution impact should be necessary. Hence, it is imperative to look for alternative fuels, which can be produced from the resources that are available within the country. Today, most of the energy demand in India is met by fossil fuels. As India is an agricultural country, there is a wide scope for the production of vegetable oils (both edible and non-edible) from different sources.

The article discusses the possibility of using blended biofuels from rapeseed oil (RO) as fuel for a diesel engine. RO blended diesel fuel (DF) and emulsified multicomponent biofuels have been investigated. Fuel physicochemical properties have been analyzed. Experimental tests of a diesel engine D-245 in the operating conditions of the external characteristic curve and the 13-mode test cycle have been conducted to investigate the effect of these fuels on engine performances. CFD simulations of the nozzle inner flow were performed for DF and ethanol-emulsified RO. The possibility of a significant improvement in brake thermal efficiency of the engine has been noted. The efficiency of using blended biofuels from RO as a motor fuel for diesel engines has been evaluated based on the experimental test results. It was shown that in comparison with the presence of RO in emulsified multicomponent biofuel, the presence of water has a more significant effect on NOx emission reduction. The cont...

The EU energy strategy for 2020 forces scientists and industries to develop new generation of bio-fuels and increase the use of the ones available nowadays. Straight vegetable oils (SVO) and waste cooking oils (WCO) could represent an interesting alternative fuel for Diesel engines, representing a good solution in some niches sectors (i.e., public transportation, hybrid or marine propulsion, etc.). As a matter of fact the use of SVO as fuel do not requires large production plants as in the case of biodiesel, thus it can be used in a large number of countries without requiring new costs. On the other hand SVO has some shortcomings due to the different characteristics comparing with the gasoil fuel. Main differences are related to its smaller heating value, a different density, and a larger viscosity, and this may provoke some problems to the injection system and power loss in a Diesel engine. Aim of this work is to analyse the behaviour of a Diesel engine in automotive configuration ...
