The main objective of this study is to investigate the effects of blends containing sunflower fuel and diesel fuel on the performance and emissions of a diesel engine. The considered parameters are brake power, specific fuel consumption and thermal efficiency as well as carbon monoxide, hydrocarbon and nitrogen oxide emissions. Blends of biodiesel, ethanol, methanol and sunflower oil with diesel fuel, each containing 15% alternative fuel in volume, were prepared. Then, these blends were tested in a direct injection diesel engine. Results obtained with these blends were compared with diesel fuel. That blends yielded usually different performance and emission characteristics compared to diesel fuel. The biodiesel blend resulted in performance parameters very close to those obtained in the use of diesel fuel. Ethanol and methanol blends yielded lower brake power, while they resulted in higher specific fuel consumption and lower carbon monoxide emissions. On the other hand, the sunflower oil blend yielded lower carbon monoxide emissions, while it caused only slight changes in the performance parameters.

PERFORMANCE EVALUATION OF GASOLINE AND E50 FOR INTER COMBUSTION ENGINE
IJRAME PUBLICATIONS, 2021
The present work represents the performance evaluation of Gasoline and E50 for the internal combustion (IC) engine. There is a lot of scope for performance evaluation to understand and adopt the various fuels for the internal combustion engine. In this work the various performance characteristics are analyzed for both the fuels. Then a comparison is made among both the fuels to understand the adoptability of these fuels. The first fuel used is 100% gasoline and the later one is 50% gasoline and 50% ethanol. In order to the performance of the engine with these fuels the emphasis is also made on compression ratio for these fuels. After the investigation it is observed that from gasoline to E50 the compression ratio is enhanced without any trouble of knocking. The investigation has resulted in two important results. First, E50 has shown a rise in power generation, engine torque and fuel consumption. Second a fall in emissions of nitrogen oxide, carbon monoxide and hydro carbon. Particularly at high compression ratio for the spark ignition engines E50 fuel gave a better performance than gasoline alone. The blending of gasoline with ethanol is a better choice for the IC engines.
A Review Paper on "Performance of Different Fuels in Internal Combustion Engine"
IRJET, 2022
This review is focused on performance of various fuels used in internal combustion engine. The Conventional fuels used are Petrol, CNG and Diesel, while new alternative fuels for petrol, CNG and diesel are Biodiesel, ethanol, hydrogen, ethanol blended with petrol and diesel. Each of these alternative have different effect on performance on internal combustion engine. The use of these alternatives is due to limited amount of petroleum available. These alternative fuels can help petroleum last longer, because fuels like hydrogen are very much in abundant quantity, while fuels like ethanol can be produced as per needs and requirements. Effectiveness of petrol machine is substantially related to contraction rate of the machine. Typically contraction rate of petrol machine ranges around 6 to 9 when contraction rate is increased beyond 9.3 possibility of eruption will be increased. Applying the affair value from the trials and with the help of fine formulas brake power, specific energy consumption, energy mass inflow rate, and brake thermal effectiveness were measured.

In countries like India, transportation by a two wheeled motorcycle is very common owing to affordable cost, easy handling and traffic congestion. Most of these bikes use single cylinder air cooled four-stroke spark ignition (SI) engines of displacement volume ranging from 100 cm3 to 250 cm3. CO and HC emissions from such engines when started after a minimum stop-time of 12 hours or more (cold-start emissions) are higher than warmed-up emissions. In the present study, a 150 cm3 single cylinder air cooled SI engine was tested for cold start emissions and exhaust gas temperature. Different gasoline-ethanol blends (E0 to E20) were used as fuel expecting better oxidation of HC and CO emissions with additional oxygen present in ethanol. The effect of glow plug assisted exhaust gas ignition (EGI) and use of catalytic converter on cold start emissions were studied separately using the same blends. Results show that with gasoline-ethanol blends, cold start CO and HC emissions were less than...
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.
Performance and Emissions Analysis of BE85-Gasoline Blends on Spark Ignition Engine
Automotive Experiences
This study aims to reveal the performance and exhaust emissions of a spark ignition (SI) engine fueled by a gasoline-bioethanol mixture. The main performance characteristics of the SI engine tested are torque, power output; thermal efficiency, brake specific fuel consumption, and brake mean effective pressure. Meanwhile, the exhaust emissions seen are carbon monoxide and hydrocarbons. The test is carried out by comparing the performance of the SI engine under standard conditions without modification with gasoline fuel, with the SI engine with modification with 85% bioethanol fuel. The mass flow of fuel is regulated by modifying the carburetor choke at 3/4 and 7/8. The results show that although slightly lower than gasoline, in general, it can be seen that bioethanol can improve SI engine performance and produce environmentally friendly exhaust emissions.

The atmospheric temperature in different regions of India is varying between 0℃ and 50℃, and because of this huge variation, it is not easy for the engine to operate under these adverse conditions. Therefore, it is very important to investigate the most suitable operating temperature for the engine to obtain the better performance and emission results. The purpose of this investigation is to analyze the problem experimentally to find the better engine performance and emissions levels by using threecylinder four-stroke SI engine computerized test rig used ethanol-gasoline different blends as engine fuel i.e. blended rates 0%, 5%, 10%, 15%, and investigate the engine operating temperature levels at which performance emission level is better with different ethanol gasoline blended fuels. In this analysis, the operational parameters of a three cylinder, four-stroke gasoline engine such as brake power (bp), brake thermal efficiency (η th) and brake specific fuel consumption (bsfc) have been experimentally investigated for different ethanol-gasoline blended fuels also examined emission characteristics such as hydrocarbons (HC) and nitric oxide (NO x). These characteristics (bsfc) are measured with constant engine speed, different engine operating temperatures i.e., coolant temperatures and constant loads of dynamometer. The results obtained on performance and emissions of engine parameters at 3000 rpm with 12 Kg of dynamometer load, i.e., brake thermal efficiency (η th), brake power (bp) and brake specific fuel consumption hydrocarbons (HC) also nitric oxide (NO x) have presented graphically with respect to the coolant temperature of the engine. The present study showed that it is suitable to operate the engine at temperature 65°C-75°C for obtaining better performance and emissions indications for gasoline and ethanol gasoline blends.
