The effect of methanol-diesel blended ratio on CI engine performance

found to be improved under high-load operating conditions. However, total unburned hydrocarbon THC and CO emissions for dual-fuel operation increased when methanol was added. In another study by Sayin et al. (2009), it was found that increasing the methanol ratio in the fuel blend caused an increase in the BSFC and decrease in BTE by about 38% and 42%, respectively. This was related to the lower heating value (LHV) of the methanol fuel, which is lower than that of the diesel fuel. It has been reported worldwide that alcohols such as methanol and ethanol have the potential to become an alternative fuel for IC engines (Yuksel & Yuksel, 2004; (Mat Yasin, Mamat, Sharma, & Yusop, 2012). Pure methanol cannot be used directly in unmodified diesel engines because it will require spark or ignition assistance or a fuel additive. However, use of diesel blended with up to 20% of methanol by volume requires only minor engine modifications (Lin & Chao, 2002). It has been reported that using blended fuel will always result in better performance than conventional fuel (Liu et al., 2007). Table 1 summarizes some of the chemical and physical properties of engine fuels that are commonly in use (Lu & Liu, 2006; Liu & Li, 2006; Liao et al., 2005). From Table 1, the exhaust gas components produced from methanol engines are found to be generally low and less toxic than other fuels. Methanol-fueled trucks and buses emit almost no particulate matter (which causes smoke, and can also be carcinogenic), and much less nitrogen oxide (NOx) than using diesel-fueled alone. Methanol extracts much more heat as it vaporizes because it has a higher latent heat of vaporization than diesel. This can lead to a cooling effect on the cylinder charge and lower NOx emissions (Bayraktar, 2008). Also, methanol is less flammable than gasoline. Methanol has a higher laminar flame propagation speed, which may contribute to the combustion process being completed earlier, which in turn leads to improved combustion efficiency. Also, the fuel blends have a longer ignition delay time than diesel fuel. The ignition delay period increases with increasing methanol (Özaktas et al., 2000). Furthermore, methanol is a high-octane fuel that offers excellent acceleration and vehicle power. Though the latent heat of methanol is high, this may increase the engine volumetric efficiency and thus increase engine power. Economically, methanol can be produced, distributed, and sold to consumers at prices that are competitive with gasoline and diesel (Warring, 1993; Yusaf, 2009; Ghobadian et al., 2009; Ghobadian, Najafi, & Nayebi, 2013; Yao et al., 2008).

Effect Of Methanol Fumigation On Performance And Emission Characteristics In A Jatropha Bio-Diesel Fueled Single Cylinder Constant Speed CI Engine

Effect Of Methanol Fumigation On Performance And Emission Characteristics In A Jatropha Bio-Diesel Fueled Single Cylinder Constant Speed CI Engine

1 INTRODUCTION Diesel engine was invented by Rudolf diesel in the year of 1858. Diesel engine could run on a various fuels that includes vegetable oils, bio-alcohol and animal fats. At the Paris exhibition, a new diesel engine powered by peanut oil as fuel, was exhibited in the year of 1900. In 1930s, there was an interest in splitting the fatty acids to obtain glycerin, which is a product of the transesterification process of vegetable oil to create a thinner product similar to petroleum and diesel. During Second World War vegetable oil was used as fuel by several countries, including Brazil, Argentina, China, India and Japan. Biodiesel derived from various vegetable oils and animal fats could be an alternative option to fossil fuels. At present, biodiesel is mainly produced from oils such as soybean oil, sunflower oil, palm oil, olive oil, corn oil, pine oil, mustard oil, peanut oil, almond oil, castor oil, coconut oil, sesame oil, fish oil etc. From these oils, biodiesel can be made and can be made, it purify to use as fuel blended with diesel. In India, oils from rape/mustard, soya, groundnut, rice bran, cottonseed, sunflowers, coconut, sesame, niger, safflower, linseed, palm oil, minor oil seeds, jatropha oils etc., Can be utilized for production of bio-diesel. There are continuously researches going on, these oil about the suitability to engine for using as alternative fuels. Each oil contains different calorific value but the jatropha calorific value is suitable as fuel and non-edible in nature. In diesel engines, use of jatropha bio-diesel emits pollutants like Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Particular matter (PM).

AN EXPERIMENTAL INVESTIGATION ON THE PERFORMANCE, COMBUSTION AND EMISSION CHARACTERISTICS OF CI DIESEL ENGINE AT VARIOUS COMPRESSION RATIO WITH DIFFERENT ETHANOL-BIODIESEL BLENDS

AN EXPERIMENTAL INVESTIGATION ON THE PERFORMANCE, COMBUSTION AND EMISSION CHARACTERISTICS OF CI DIESEL ENGINE AT VARIOUS COMPRESSION RATIO WITH DIFFERENT ETHANOL-BIODIESEL BLENDS

Adding solvents like 2% emulsifier agent prevents the separation and ensure the similarity. The increased compression ratio has a similar effect as raising the inlet air temperature which results in gradual increase in the intake pressure. The compression ratio modifications effects ignition timing, final temperature and pressure at the end of the compression process [2]. Compression ratio is raised up to 19.5:1 with the help of higher latent heat of vaporization, higher auto ignition temperature which improves of the efficiency of the engine [3]. The mean BTE of engine is increased more than 33%, when the compression ratio is raised gradually from 18 to 20. By increasing the CR up to the maximum value which results in improvement of the effective pressure by using hydrous ethanol, while reduction of Mean Effective Pressure (MEP) and Break Thermal Efficiency (BTE) occurs by increasing compression ratio [4]. Increased CR leads to high cylinder temperature which causes faster evaporation of ethanol blends resulting in improvement of the combustion [5].

The effect of compression ratio and alternative fuels on performance and exhaust emission in a diesel engine by modelling engine

ABSTRACT: This study investigates the effect of compression ratio and different fuels on engine performance and exhaust emissions in a 6.8L turbocharged industrial diesel engine. For carried out this work, a 6 cylinder four stroke engine with gamma technologies power software is modelled and the effect of compression ratio (15:1 - 19:1) and alternative fuels (Diesel, Ethanol, Methanol, Decane, Soybean biodiesel, Diesel- Ethanol) at wide open throttle and various speeds from 800-2400 rpm are presented. The results indicate that the brake specific fuel consumptions of decane fuel at a compression ratio of 17:1 is lower than those of other fuels and also the maximum brake torque obtained with decane fuel at 1400 rpm. At this engine observed that decane fuel has higher brake power as compared to other fuels used due to higher heating value content. The emission results show that diesel fuel emitted more Carbon monoxide and Carbon dioxide emissions but soybean biodiesel (B100) has less Carbon monoxide, whereas highest oxides of nitrogen is founded with soybean biodiesel. Carbon monoxide and Carbon dioxide emissions are very close to each other when used decane and diesel fuel. In general decane fuel has higher performance and soybean biodiesel had fewer emissions at a compression ratio of 17:1.

Effect of Ethanol Blended with Cottonseed Oil Methyl Ester on Engine Performance and Emission in a DI Diesel Engine by Varying Injection Pressure

sodium hydroxide (NaOH) are thoroughly mixed until it is properly dissolved. The solution obtained is mixed with Cottonseed Oil in three-way flask and it is stirred properly. The methoxide solution with Cottonseed Oil is heated to 60°C and it is continuously stirred at constant rate for 1 hour by stirrer. The solution is poured down to the separating beaker and is allowed to settle for 5 hours. The glycerine settles at the bottom and the methyl ester floats at the top (coarse biodiesel). Methyl ester is separated from the glycerine. This coarse biodiesel is heated above 100°C and maintained for 10-15 minutes to remove the untreated methanol. Certain impurities like sodium hydroxide (NaOH) are still dissolved in the obtained coarse biodiesel. These impurities are cleaned up by washing with 300 ml of water for 1000 ml of coarse biodiesel.

Effect of Silver Nano-Particle Blended Biodiesel and Swirl on the Performance of Diesel Engine Combustion

Effect of Silver Nano-Particle Blended Biodiesel and Swirl on the Performance of Diesel Engine Combustion

Addition of some metal and metal oxide in the form of nano-powder to the base fuel may enhance the properties of the fuels. This is due to the interesting properties of nano- particles like higher specific surface area, thermal conductivity, catalytic activity and chemical properties as compared to their bulk form. Many researchers have used nano-particles as additives in diesel as well as biodiesel as new hybrid fuel blends (Williams & Van den Wildenberg 2005)1. They reported properties of nano-particles such as size, thermal conductivity and chemical properties affect the performance and emission characteristics of engine. Reduced size of the nano-particles increased specific surface, surface to volume ratio, and surface area improving catalytic reactivity and magnetic properties as compared to their bulk form. Hence metal and metal oxide nano-particles addition to biofuel will improve the performance as well as reduce the harmful gases from engine exhaust (Jones et al. 2011)2. Adding aluminium nano-particles to ethanol and diesel as well as to biodiesel may enhance the ignition properties, faster burning, reduced incomplete combustion and ignition delay with heat built up in the fuel due to reactive nature of aluminium nano-particles added (Kao et al. 2008; Allen et al. 2011; Tagi et al. 2008; Basha and Anand 2010)3,4,5,6. Addition of cerium oxide nano-particles to biodiesel may also be effective as they enhanced surface area to volume ratio. Flash point of biodiesel, which is an indication of the volatility, was found to increase with the inclusion of such additives making them safer fuels. The viscosity of biodiesel was found to increase with the addition of cerium oxide nano-particles to biodiesel. The viscosity and the volatility were found to hold direct relations with the dosing level of the nano-particles (Sajith et al. 2010; Selvan et al. 2009)7,8. Performance and emission characteristics of a diesel engine operated on CNT- diesel blends have been experimentally investigated. Substantial enhancement in the brake thermal efficiency and reduced harmful pollutants were reported for such nano-additive-biodiesel blends compared to jatropha biodiesel and diesel. This could be due to better combustion associated with such novel hybrid nano-liquid fuel blends when used in diesel engines (Sabourin et al. 2009)9. Therefore, nano-particles can function as both catalyst and an energy carrier when used in base fuels in diesel engines. In addition, small scale of nano-particles, also facilitate stability of fuel suspensions when used with base fuels (Basha and Anand 2011)10.

MODELING AND ANALYSIS OF PERFORMANCE, COMBUSTION AND EMMISSION CHARACTERISTICS OF JATROPHA METHYL ESTER BLEND DIESEL FOR CI ENGINE WITH VARIABLE COMPRESSION RATIO

MODELING AND ANALYSIS OF PERFORMANCE, COMBUSTION AND EMMISSION CHARACTERISTICS OF JATROPHA METHYL ESTER BLEND DIESEL FOR CI ENGINE WITH VARIABLE COMPRESSION RATIO

An experimental study was conducted on a four stroke single cylinder compression ignition engine to determine the performance, combustion and exhaust emission characteristics under different compression ratio using an alternate fuel. The raw oil from the jatropha seed was subjected to transesterification process and is supplied to the engine as jatropha methyl ester (JME) blended with diesel. The blends used in our paper are 10%, 20% and 30%. We found that the performance of the engine under VCR is maximum at 20% blend for CR18. The fuel consumption is also found to be increased with, a higher proportion of jatropha curcas oil in the blend. But BSFC is low at 20% JME-D. Emission was found to be optimum at CR18 for all blends of the methyl ester. At high engine load, the peak cylinder pressure was found to be higher for 20% JME-D under compression ratio 18. Using STAR CD software, three dimensional simulations are deployed and the results generated are compared against the experimental output.

Dual fuel combustion in a CI engine powered by blended diesel biodiesel fuel and simulated gasification gas

Internal combustion engines (ICE) has had significant impact on the human life as a lightweight source for useful generation of power and heat and combined power/heat cycle. There has been continuous research and development both on the engine hardware and on the fuel the ICEs consume for better performance and lower emissions. The main concept of ICE is the conversion of fuel energy into thermal energy and thereby into useful mechanical power using either spark or compression ignition systems. The need for reducing fossil fuel dependence and the emissions from (ICE) has drawn attention to the necessity of research for suitable renewable energy source. There are many alternatives that can be used as energy source replacements to fossil fuel, including renewable fuel and nuclear energy resources [1]. When searching for choices of embracing the utilization of what sort of alternative sources to use in ICE, the effect on the environment and economic implications is very important. Alternative gaseous fuels are the most effective sources to replace fossil diesel fuel, because it produces very much lower emissions of nitrogen oxides (NO X ),

PERFORMANCE AND EMISSIONS ANALYSIS OF DIESEL BLENDED WITH NAHAR BIODIESEL BY VARYING COMPRESSION RATIO OF CI ENGINE

The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The rapid extraction and consumption of fossil fuels have led to a reduction in petroleum reserves [1]. Biodiesel is an alternative fuel for diesel engines that is produced by chemically combining vegetable oils and animal fats with an alcohol to form alkyl esters. Extensive research and demonstration projects have shown that it can be used pure or in blends with conventional diesel fuel in unmodified diesel engines [3]. Interest in biodiesel has been expanding recently due to government incentives and high petroleum prices. While the current availability of vegetable oil limits the extent to which biodiesel can replace petroleum to a few precent, new oil crops could allow biodiesel to make a major contribution in the future.[2][5]

Experimental Investigation of Performance, Emission and Combustion Characteristic of CI Engine using Methanol Blended with Kusum Biodiesel and Diesel

Experimental Investigation of Performance, Emission and Combustion Characteristic of CI Engine using Methanol Blended with Kusum Biodiesel and Diesel

The use of alcohol additives include methanol and ethanol are very practical in the biodiesel blends due to its miscibility with the pure biodiesel [1] . Alcohol additives are very helpful to reduce the viscosity and density of the biodiesel which is higher compared to standard mineral diesel. The alcohol additives improve the combustion efficiency and produce lower exhaust emission when fuelled the diesel engines. Ethanol and methanol has approximately 35% and 30% higher oxygen in basis as compared to mineral diesel that help diesel engine to achieve higher complete combustion [2]. For the developing countries of the world, fuels of bio-origin can provide a feasible solution to the crisis. The fuels of bio-origin may be alcohol, vegetable oils, biomass, and biogas. Biodiesel is a nonpetroleum-based fuel defined as fatty acid methyl or ethyl esters derived from vegetable oils or animal fats and it is used in diesel engines and heating systems. Thus, this fuel could be regarded as mineral diesel substitute with the advantage of reducing greenhouse emissions because it is a renewable resource. However, the high cost of biodiesel is the major obstacle for its commercialization, the biodiesel produced from vegetable oil or animal fat is usually more expensive than petroleum- based diesel fuel from 10 to 40%. Moreover, during 2009, the prices of virgin vegetable oils have nearly doubled in relation to the early 2000. This is of great concern to

Performance Test on Diesel Biodiesel – Propanol Blended Fuels in CI Engine

The palm oil available in the south region of India. Another reason for selecting palm is that it contain high free fatty acid content which increases the yield of biodiesel. Palm oil based biodiesel do not cause any ignition delay. The ignition delay decreased as the palm oil content increased. This is due to the higher oxygen content in the palm oil based biodiesel. The production capacity of palm oil is more when compared to other vegetable oils. at an average production capacity of 5000 kg oil/napalm tree oil is the most efficient energy crop,and about 2.5 times more efficient as its next closest plant/oil seed, coconut oil.Palm oil is carbon neutral, therefore harmful gases like carbon dioxide, carbon monoxide are not released, and since these are greenhouse gases their harmful impacts are prevented. it also eliminates harmful emissions. palm oil is to achieve energy independence and to protect the environment care. Methanol used in the reaction had more than 99.25% purity, sodium hydroxide used as catalyst Transesterification occur at a faster rate in the presence of an alkaline catalyst than in the presence of the same amount of acid catalyst.

Effect of Blend Ratio of Plastic Pyrolysis Oil and Diesel Fuel on the Performance of Single Cylinder CI Engine

Pritinika Behera et al. [2] [2013] in their research paper have stated their experiments on DI diesel engine with transformer oil. The experiments were done for single cylinder CI engine fuelled with used transformer oil (UTO) and Diesel Blends on varying concentration of UTO from 10% to 60%, out of which UTO40 was found to be optimum blend. In this research, ignition delay of UTO – Diesel blend was found to be shorter by 1 – 3 °CA than the same of Diesel Fuel, while HC, CO and NO emissions were found to be higher with 5.9% lower smoke value than those of Diesel Fuel. S. Murugan et al. [3] [September 2012], in their research paper of Diesel engine fuelled with Tyre Pyrolysis Oil (TPO), have stated that the engine performs better with lower emissions when DEE was admitted at the rate of 170 g/h with TPO and the peak pressure for TPO – DEE with 130 g/h flow rate is higher by about 3 bar than DF at full load. The thermal efficiency and NOx emissions were found to be reduced by 2.5% & 5% respectively for TPO – DEE than the diesel fuel, while HC, CO and smoke emissions were found to be higher for TPO–DEE operation by 2%, 4.5% and 38% respectively than diesel mode. Ignition delay was increased by 2.8 °CA for TPO – DEE than diesel fuel. Abhishek Sharma et al. [4] [March 2013], in their Investigation on the behaviour of a DI diesel engine fuelled with Jatropha Methyl Ester (JME) and Tyre Pyrolysis Oil (TPO) blends, had used five different blends of varying TPO of concentration from 10% to 50%. There was a reduction in the efficiency with 30%, 40% and 50% TPO in the blend at full load. It was found that JMETPO blend could be directly used as a fuel without any engine modification. Among all the blends, JMETPO20 was found to deliver the optimum results. For JMETPO20 CO, HC, Smoke emissions, cylinder peak pressure and combustion duration were found to be reduced by 9.09%, 8.6%, 26%, 1 bar and 0.54 °CA respectively at full load, while BSEC and NO X emissions were found to be increased by 7.8% and 24% respectively.

Experimental Evaluation Of A CI Engine Running On Blends Of Diesel And Methanol Fuel With Copper Oxide Nano Particles

Experimental Evaluation Of A CI Engine Running On Blends Of Diesel And Methanol Fuel With Copper Oxide Nano Particles

Biofuel is the better alternative for the increased number of pollution and the decrease in fossil fuels. It has more oxygen content which leads to more emissions. And also, it has less calorific value with increased fuel consumption. So trans esterification process was done to obtain biofuel from the oil which has the specified properties as per the diesel engines. The biofuel obtained was used as a blend with diesel fuels in order to increase the performances of the fuel. But also, the nitrous oxide emissions and the soot particle emissions were increased when biodiesel was used in the diesel engines. To avoid this copper oxide additives were used in the blends. It was mixed with the biodiesel with the help of a magnetic stirrer. This improved the efficiency of the additives. It reduced the specific fuel consumption, increased brake thermal efficiency and leads to complete combustion. And also, the brake power increases with the increase in load when additive is added with the biodiesel. These additives increased the thermal efficiency and also increased the heat transfer capacity of the fuel. This is due to the main properties of the additives such as higher specific surface area, thermal conductivity, catalytic activity and chemical properties. And also, it increases the surface area to volume ratio that enables oxidation capacity.
