Experimental Evaluation of Performance and Emission Characteristics of a Diesel Engine Fuelled with Neem Methyl Ester

The dwindling fossil fuel resources and the environmental degradation have spurred research interest to find better renewable alternative energy sources. Biodiesel is one such viable promising alternative fuel, which can be extracted from various renewable vegetable oils. In the present study, biodiesel extracted from neem oil is characterized for engine performance and emission analysis is done at various compression ratios (CR) and fuel blends. The brake thermal efficiency (BTE) of the blend B20 is considerably higher than that of diesel at CR 18, 20, and 22. The specific fuel consumption (SFC) increases with diesel blends due to a higher calorific value of diesel in comparison with biodiesel. All the biodiesel blends had lower carbon monoxide (CO) emissions compared with diesel, which indicates better combustion due to the presence of inherent oxygen. At lower CRs, the in-cylinder temperature is lower, which in turn reduces the nitrogen oxide (NO X ) emission. The overall

Performance, Emission and Combustion Characteristics of a Diesel Engine with Methyl Ester of Mango Seed Oil and Diesel Blends

Abstract-- Petroleum based fuels worldwide have not only resulted in the rapid depletion of conventional energy sources, but have also caused severe air pollution. The search for an alternate fuel has led to many findings due to which a wide variety of alternative fuels are available at our disposal now. The existing studies have revealed the use of vegetable oils for engines as an alternative for diesel fuel. However, there is a limitation in using straight vegetable oils in diesel engines due to their high viscosity and low volatility. In the present work, neat mango seed oil is converted into their respective methyl ester through transesterification process. Experiments are conducted using various blends of methyl ester of mango seed oil with diesel in a single cylinder, four stroke vertical and air cooled Kirloskar diesel engine. The experimental results of this study showed that the MEMSO biodiesel has similar characteristics to that of diesel. The brake thermal efficiency, unburned hydrocarbon and smoke density are observed to be lower in case of MEMSO biodiesel blends than diesel. The CO emission for B25, B50 and B75 are observed to be lower than diesel at full load, whereas for B100 it is higher at all loads. On the other hand, BSFC and NO x of

Effect of Injection Timing on Performance and Combustion Characteristics of a Diesel Engine Fuelled with Diesel and Methyl Ester of Sunflower oil

The physical properties of the biodiesel fuel such as viscosity, flash point effect the different process occurring within the diesel engine cylinder; including fuel evaporation, fuel mixing with air, fuel atomization and fuel burning and engine performance. In metering the desired amount of fuel at correct time depending on engine operating conditions plays an important role is injection timing (IT). The increase of injection timing is recorded as one of the basic parameters that tend to reduce particulate matter emissions and fuel consumption in addition to other influences; including the increase of fuel portion burned by premixed combustion, the increase of mixture homogeneity, the increase of local A/F ratio, the decrease of combustion duration, the increase of the in-cylinder peak pressure, and the increase of NOx emissions. Kumar et al. 1 studied the effect of compression ratio, fuel atomization, Injection Timing, fuel quality, combustion rate, A/F ratio, intake temperature and pressure on engine performance parameters. Authors founded that, the increase in air motion into diesel engine improves the fuel atomization, the heat release rate and reduces the levels of exhausted emissions. Sayin et al. 2 studied the effect of fuel atomization and fuel distribution through combustion chamber using a single cylinder diesel engine operated with canola oil methyl esters (COME) and its blends with diesel fuel. The experimental results showed that, fuel exhibits different combustion and performance characteristics for different IT and engine loads. From their study, Sayin et al. 2 Kannan and Udayakumar 3 studied the effect of IT on performance and emissions from diesel engine. Authors concluded that, good performance and low emissions occur at high IP of 200 bar. Canakci et al. 4 observed the decrease of engine mechanical performance parameters and the increase of most engine emissions (smoke opacity, UHC and CO) except NOx and CO 2 when the injection pressure becomes

Effect of Tetra Hydro Furan on Performance and Emission Characteristics of Ci Engine Fuelled With Methyl Ester of Jatropha

Effect of Tetra Hydro Furan on Performance and Emission Characteristics of Ci Engine Fuelled With Methyl Ester of Jatropha

252 The gas phase emissions of vegetable oil are higher due to its complex structure, composition, increased combustion duration and ignition delay with vegetable oils as compared to diesel[9]. Different methods have been considered to reduce the viscosity of vegetable oils such as dilution, micro emulsification, pyrolysis, catalytic cracking, transesterification etc. The experimental investigation on the performance of rubber seed oil fuelled diesel engine by dual fuelling with hydrogen showed that the brake thermal efficiency was improved and the emissions such as CO, HC, and smoke reduced with the induction of hydrogen in dual fuel mode [10]. The most commonly used method to reduce the viscosity of the vegetable oil is the transesterification. In India, a large variety of vegetable oils are available in huge amounts. A study on the combustion analysis of diesel engine fuelled with jatropha oil methyl esterdiesel blends reported that the ignition delay, maximum heat release rate and combustion duration were lower for Jatropha oil methyl ester and its blends compared to diesel. The emissions except nitrogen oxides were lower with Jatropha oil methylester and its blends compared to diesel[11]. In the study of effect of injection time and injection pressure on CI engine fuelled with methyl ester of thevetia peruviana seed oil it was observed that the brake thermal efficiency increased and CO, HC, and smoke emissions reduced significantly with advancing the fuel injection time and increased injection pressure [12]. A study on the mahua oil derivatives as a renewable fuel for diesel engine showed that the brake thermal efficiency of methyl and ethyl esters of Mahua oil was slightly higher than that of diesel. The emissions of HC, CO, and Bosch smoke number (BSN) comparatively lower than that of diesel[13]. In the present work, it is proposed to blend Tetra Hydro Furan in various proportions with the MEJO in this work. The performance and emission characteristics of a diesel engine are studied experimentally by blending 1%, 2%, and 3% of Tetra Hydro Furan with MEJO.

Performance, Emissions and Combustion Characteristics of a Single Cylinder Diesel Engine Fuelled with Blends of Jatropha Methyl Ester and Diesel

ABSTRACT: In order to meet the energy requirements, there has been growing interest in alternative fuels like biodiesels, ethyl alcohol, biogas, hydrogen and producer gas to provide a suitable diesel substitute for internal combustion engines. An experimental investigation was performed to study the performance, emissions and combustion characteristics of diesel engine fuelled with blends of Jatropha methyl ester and diesel. In the present work three different fuel blends of Jatropha methyl ester (B10, B20, B40 and B100) were used. The increments in load on the engine increase the brake thermal efficiency, exhaust gas temperature and lowered the brake specific fuel consumption. The biodiesel blends produce lower carbon monoxide & unburned hydrocarbon emission and higher carbon dioxide & oxides of nitrogen than neat diesel fuel. From the results it was observed that the ignition delays decreased with increase in concentration of biodiesel in biodiesel blends with diesel. The combustion characteristics of single-fuel for biodiesel and diesel have similar combustion pressure and HRR patterns at different engine loads but it was observed that the peak cylinder pressure and heat release rate were lower for biodiesel blends compared to those of diesel fuel combustion.

Performance and Emission Testing of Neem Oil Methyl Ester (Biodiesel) in Internal Combustion Engine

Performance and Emission Testing of Neem Oil Methyl Ester (Biodiesel) in Internal Combustion Engine

Agarwal et al. [2012] evaluated the performance, emission and combustion characteristics of Neem Oil Methyl Ester (Biodiesel) and found that Brake specific fuel consumption for biodiesel and its blends were higher than mineral diesel however brake thermal efficiency of all biodiesel blends was also higher than mineral diesel. BSCO and BSHC emissions for biodiesel fuelled engine operation were lower than mineral diesel however BSNOx emissions were higher for biodiesel blends. Combustion started earlier for higher biodiesel blends however start of combustion was slightly delayed for lower biodiesel blends in comparison to mineral diesel. Rate of heat release trends for all the biodiesel blends were almost identical to mineral diesel. Combustion duration for biodiesel blends was shorter than mineral diesel. This indicates that lower blends of biodiesel (upto B20) can be used in unmodified CI engines without any compromise in engine performance and emission characteristics.

Emissions and Performance Evaluation of DI CI - VCR Engine Fuelled with Honne oil Methyl Ester /Diesel Blends

Emissions and Performance Evaluation of DI CI - VCR Engine Fuelled with Honne oil Methyl Ester /Diesel Blends

At higher compression ratios (16 to 18), combustion of fuel is efficient due to high temperature of compressed air. Due to which, the exhaust emissions are found to reduce at higher CRs. Also at higher CRs, smoke is less due to complete combustion of fuel. However, the NOx emissions are found to increase at higher CRs with Honne biodiesel as compared to Diesel. There is need to trade off between NOx and smoke emission. So the selection of CR can be based on the combined effect on thermal performance and emission characteristics. It is preferable to operate the engine at CR of 18 for optimum thermal performance. If NOx is considered then it is better to operate at CR 16.But it causes decrease in BTE of about 13% and increase of BSFC of about 13% which are not recommendable just to reduce NOx emissions.

The Combustion and Emission Characteristics of a Diesel Engine Fuelled with Used Cooking Oil Methyl Ester and its Diesel Blends

Transesterified vegetable oils (biodiesel) are promising alternative fuel for diesel engines. Used vegetable oils are disposed from restaurants in large quantities. But higher viscosity restricts their direct use in diesel engines. In this study, used cooking oil was dehydrated and then transesterified using an alkaline catalyst. The combustion, performance and emission characteristics of Used Cooking oil Methyl Ester (UCME) and its blends with diesel oil are analysed in a direct injection C.I. engine. The fuel properties and the combustion characteristics of UCME are found to be similar to those of diesel. A minor decrease in thermal efficiency with significant improvement in reduction of particulates, carbon monoxide and unburnt hydrocarbons is observed compared to diesel. The use of transesterified used cooking oil and its blends as fuel for diesel engines will reduce dependence on fossil fuels and also decrease considerably the environmental pollution.
