ANALYSIS OF GENERATOR EMISSION FUELLED WITH PETROL -KEROSENE MIXTURE (original) (raw)

INVESTIGATION OF EMISSION CHARACTERISTICS OF SI ENGINE GENSET FUELLED WITH PETROL-KEROSENE BLENDS

Due to the continuous consumption of energy resources, the price of conventional fossil fuel is increasing too fast and lead to additional burden on the economy of the importing nations. The scarcity and depletion of conventional petrol sources are cause of great concern worldwide and has promoted research into alternate energy sources for IC engine Spark Ignition Engine is widely used prime mover due to its smooth operation & low maintenance. The Blending of alternative fuel with the conventional fuel may be the solution of scarcity of conventional fuel for the spark ignition engine. The present work is mainly concerned with an experimental investigation to study the petrol engine performance, combustion, noise and emission characteristics using blends of petrol & kerosene. The performance characteristics for different blends are evolved in running the engine under steady state conditions. It is observed that 80 % Petrol and 20 % Kerosene provides the lesser NOX and emission of HC compared to other blends. 20 % and 40 % petrol give higher value of CO at lower load but as the load increases, the concentration of CO by volume decreases, and the 20 % kerosene can be preferred at higher load as it will give less CO emission. With the overall results of engine performance and emission characteristics the optimum percentage of blend of petrol and kerosene is found out to be 80:20 (80% petrol and 20% kerosene).

Comparison of Spark Ignition Engine Performance and Emission Analysis Using Gasoline, LPG and Mixture Fuels

IJMTST, 2020

Emissions of higher amount of pollutants are a major concern in the use of conventional fuels such gasoline and diesel. Exhaust emissions such as nitrogen oxides (NOx), carbon monoxides (CO) and sulphur dioxides (SO2) affect the human body adversely. The problem of emission of higher amount of harmful pollutants can be diluted by use of alternate fuels such as liquefied petroleum gas (LPG), gasoline and their mixtures. The emission level can be brought down to safer level set by international agencies. In this work the engine was tested using LPG, gasoline and with gasoline and LPG-air mixture; so that comparative study of the emissions of pollutants gases and engine performance can be made. The results of the experiments have shown improvement in efficiency of LPG mode engine in comparison to gasoline and mixture fuel engine. Simultaneously, there was a reduction in HC and CO emissions of LPG and mixture fuel engines with reference to gasoline mode engines. On the other hand, the pure LPG fuel system showed a tremendous reduction in emissions, delivered a comparable torque as compared to gasoline and mixture fuel engine. The fuel consumption rate of LPG fuel mode is slightly higher than the gasoline mode. LPG mode is more economical but in most of the cases it results in about 10-15% power loss.

Effect of Compression Ratio on Performance and Emission Characteristics of a Spark Ignition Engine for Alternative Fuels

This paper deals theanalysis of performance and emissions of a single cylinder, four stroke, spark ignition engine for gasoline, kerosene and ethanol blended gasoline (E15) fuels. The effect of different compression ratios (4.5 and 9.5) on performance and emission characteristics of engine were studied at constant speed (3000 rpm), with different loads. In addition to this, the mixture formation process for these fuels was also studied using Computational Fluid Dynamic software. The results indicate the engine with kerosene at all compression ratios gives the highest combustion and thermal efficiency as compared to other fuels. The combustion efficiency with kerosene increased further from 74 % (CR: 4.5) to 81 % (CR: 9.5) at 50 % load. CO and HC emission of the engine fuelled with kerosene is least as compared to other fuels. However NOX emission increased significantly. It is also confirmed through CFD study that the mixture formation rate increased with kerosene.It is emerged from...

Experimental assessment of various fuel additives on the performance and emission characteristics of the spark ignition engine

International Journal of Ambient Energy, 2019

The aim of this experimental investigation is to analyse the performance and emission characteristics of spark ignition engine running on petrol doped with various additives. Additives used in this research work are toluene, benzene and ethanol at 20% concentrations on volume basis. The engine test setup consists of single cylinder, four stroke and stationary petrol engine. The engine performance with petrol doped with ethanol was found to be better than pure petrol while the performance with toluene as additive was found to be slightly poorer than petrol at low loads. However, at higher loads, engine performance with toluene doped petrol was better than that with pure petrol. For all values of loads, the engine performance with benzene was found to be poor. The short-term experimental results had shown that petrol containing 20% toluene and 20% benzene as additives can be successfully substituted without any alteration in engine design.

Influence of the ignition system parameters on the ecological indicators of the automobile gas-fueled engine

Ukrainian journal of mechanical engineering and materials science

The structure of the automobile service, since the beginning of the independence of Ukraine, has changed acutely. The number of private vehicles, the quality of service of which depends on the owner only, has increased. In addition to already existing automobile transport enterprises which has at least some existing production facilities with available cars of post-Soviet production and Russian cars of the middle time of Ukraine's independence, a large number of private small motor vehicles companies without any production base have appeared (in the best occasion with the available storage area), technical condition of the movable composition of which does not meet the requirements of European countries and the main transporting direction of these enterprises was concentrated in the directions of post-Soviet countries. In order to maximize efficiency, the owners of such vehicles carry out the transformation of power supplies to the system supplied with gas fuel. Despite the sufficient number of advantages, such refurbishment requires the introduction of constructive modifications and adjustments also in the ignition system of motor vehicles. And here, in the absence of systematic state control, many of the car owners in pursuit of maximum economy, trying not to make changes, causing violations in the work of car systems, which leads not only to the growth of fuel consumption and reducing of the effective performance of the engine, but also to increasing of emission of toxic components with the exhaust gas flow of the car engines. In conditions of Ukrainian cities, where emissions of toxic components by transport sources are up to 90% of all harmful effects [11], the search for ways to improve the system of technical service of vehicles is relevant in order to control and reduce the level of environmental hazards from the operation of vehicles. Therefore, researches that focus on determining the influence of regulation of the ignition system of engines powered by gas fuel, on the example of the spark plug gap influence on the indicators of the content of the components of the exhaust gases, are relevant. The method of research on the influence of the spark plug gap on the change in the composition of exhaust gases was developed in the paper, the research was carried out on ZAZ Lanos 1.4 engine MeMZ 317, on which is an assembly of gas equipment of the 4th generation Stag 200 GoFast. All experiments were carried out on the equipment of the Training Center for Computer Diagnostics of Vehicles "Lviv Polytechnic-Bosch Academy". A set of new Champion RN9YC spark plugs was used, the gap of which was changed from 0.6 to 1.4 mm with a pitch of 0.1 mm. According to the values of the gap between the electrodes of the spark plug, with the use of Bosch BEA 460 gas analyzer, the content of the following components of the exhaust gases CO, HC, O2 and CO2 is determined for two engine's crankshaft frequencies.

Performance and Emissions of a Spark Ignition Engine Running on Gasoline Adulterated with Kerosene

SAE Technical Paper Series, 2009

The aim of this study, which is the first of its kind, is to compare experimentally the effects of different ternary blended fuels, e.g., ethanol-methanol-gasoline (EM), n-butanol-iso-butanol-gasoline (niB) and iso-butanol-ethanol-gasoline (iBE), on engine performance, combustion and pollutant emission characteristics to demonstrate the best potential one from these ternary fuel blends as alternative to fossil fuel. The experiments were performed at similar operating conditions and low content rates of fuel blends (3-10 vol% in gasoline) with varying engine speeds between 2600 and 3400 r/min at half throttle opening position of spark ignition engine. The results showed that the engine performance (volumetric efficiency, torque and brake power) increased, while pollutant emissions (carbon monoxide (CO) and unburnt hydrocarbons (UHC)) decreased at using EM fuel blends, compared to other blended fuels. It was also found that the highest emissions and the lowest performance among the blended fuels are introduced by niB, while iBE presented a moderate level of performance and emissions between niB and EM. On the other hand, the performance of niB and iBE is lower than the base fuel (neat gasoline) but EM showed a higher performance than the base fuel. The emissions of EM, niB and iBE are all lower than the base fuel.

Investigation on Performance Characteristics of Petrol Engine Using Alternate Fuel

In the present scenario the S.I. engines being used in automotives by various manufactures are not properly suitable to out climatic condition. As our country is among tropical countries where the variation in the temperature is having very vast range i. e. from 0ºC to 48ºC in various regions of the country. Looking in to this vast varying temperature range it is very difficult to say that which temperature is most suited to operating condition of engines and gives us best performance level as for as SFC and brake power is concerned. In my work I have tried to investigate the best option to run the S.I. engine and simultaneously to maintain the emission norms. Petrol reserves are getting exhausted and it is recommended to find the alternate solution to it. In the present work the potential of methanol is being explored to serve as alternate fuel. This work is carried out with the use of petrol and methanol on a three cylinder, four stroke, petrol Maruti 800 engine connected to eddy current type dynamometer for loading was adopted to study engine power, fuel economy, engine exhaust emissions of hydrocarbon, oxides of nitrogen in the exhaust. The performance results that are reported include brake power and specific fuel consumption (SFC) as a function of engine coolant temperature; i.e. 50ºC, 60ºC, 70ºC and 80ºC with varying engine speed of 1500, 2000, 2500, rpm. Today research and development in the field of gasoline engines have to face a double challenge: on the one hand, fuel consumption has to be reduced, while on the other hand, ever more stringent emission standards have to be fulfilled. The development of engines with its complexity of in-cylinder processes requires modern development tools to exploit the full potential in order to reduce fuel consumption. There are many strategies for improving fuel economy and reducing exhaust emission. Hydrocarbon emission (HC) and carbon monoxide (CO). And finally it is concluded that no remarkable difference is recorded. With use of methanol instead of petrol the variation is marginal and can be attributed to the cycle temp and combustion efficiency. Thus methano l is recommended for use as an alternative fuel for petrol engine in coming future.

Experimental study on the effects of kerosene-doped gasoline on gasoline-powered engine performance characteristics

Journal of Petroleum and Gas Engineering, 2010

This investigation was carried out to study the engine-out emissions from a four-stroke, four-cylinder, water-cooled spark ignition (SI) engine with kerosene blended gasoline with different proportions of kerosene ranging from 0-50% by volume in step of 10%. Gaseous exhaust emissions were measured with the aid of pocket gas TM-portable gas analyzer. The experimental results showed that the engine-out emissions increase with increase concentration of kerosene in the blend. The analyses gave increase ranging from 21.7-53% for carbon monoxide (CO), 23.4-57.1% for unburnt hydrocarbon (HC) and 2.4-8.2% for particulate matter (PM). The experiment also showed increase in specific fuel consumption (SFC) for all load conditions ranging form 34-36%. Measures needed to reduce fuel adulteration were suggested. The measures encompass effective monitoring mechanism and enforcement of heavy penalty on sale of adulterated fuels.
