Performance And Emissions

Biodiesel is an alternative diesel fuel that can be produced from renewable feedstocks such as vegetable oils, waste frying oils, and animal fats. It is an oxygenated, non-toxic, sulphur-free, biodegradable, and renewable fuel. Many engine manufacturers have included this fuel in their warranties since it can be used in diesel engines without significant modification. However, the fuel properties such as cetane number, heat of combustion, specific gravity, and kinematic viscosity affect the combustion, engine performance and emission characteristics. In this study, the engine performance and emissions characteristics of two different petroleum diesel fuels (No. 1 and No. 2 diesel fuels) and biodiesel from soybean oil and its 20 per cent blends with No. 2 diesel fuel were compared. The results showed that the engine performance of the neat biodiesel and its blend was similar to that of No. 2 diesel fuel with nearly the same brake fuel conversion efficiency, and slightly higher fuel consumption. CO2 emission for the biodiesel was slightly higher than for the No. 2 diesel fuel. Compared with diesel fuels, biodiesel produced lower exhaust emissions, except NO x.

In the present work on unheated Corn oil methyl ester and Preheated Corn oil methyl ester is used to prepare different concentration blends with diesel, B20, B40 and B60 were used as alternative fuels in a compression ignition engine. The properties like calorific value, flash point, fire point and viscosity of these oils were determined. The viscosity of corn oils has been reduced through transterification process. The waste heat energy from the exhaust gas was reused to preheat the corn oil around 80°C by adjusting the flow rate of exhaust gas.  The performance and emission characteristics of a single cylinder, direct injection diesel engine were determined using unheated corn oil, Preheated Corn oil and diesel. Brake thermal efficiency of preheated B20 was more than other blends and unheated fuels but equal to diesel fuel. Brake specific fuel consumption, CO2 and HC of preheated B20 were less than unheated fuels and diesel. However, the NOx emission of preheated B20 was little higher than unheated fuels and diesel due to high combustion temperature. By considering the result of all the factors, preheated B20 blend was found to be a suitable alternative for diesel fuel.

In the present experimental investigation, the performance and emission characteristics of four stroke single cylinder water-cooled DI diesel engine using dual hybrid biodiesel is evaluated. Dual hybrid biodiesel produced from Simarouba Oil Methyl Ester (SuOME) and Jatropha Oil Methyl Ester (JOME) is used as a fuel to run the engine. Both the methyl esters are mixed in equal % and blended with diesel (B20 to B100). The fuel properties such as kinematic viscosity, calorific value, flash point, carbon residue and specific gravity were found for the prepared biodiesel. The results showed that B20 has almost closer brake thermal efficiency compared to that of the conventional diesel fuel. Except NOx, B100 has recorded very less emission of CO, CO2 and HC compared to that of diesel fuel.

Palm oil methyl ester (POME) produced from crude palm oil have some excellent properties which makes it a feasible alternative to diesel fuel. However, its higher oxygen content makes it nitrogen oxide emission prone when burned in diesel engines. This problem can be resolved by emulsifying POME with distilled water in the presence of suitable surfactant. Two phase water in oil emulsion is prepared by using ultrasonic bath sonication. SPAN 80, a lipophilic surfactant is used for 1% by volume to prepare the emulsion. Water quantity in the emulsion is varied by 5% and 10% by volume and stability study is performed. It is found that emulsion with 5% water is more stable. Thereafter, POME emulsion samples are prepared with 5% water and tested in a variable compression ratio diesel engine. The performance and emission characteristics are investigated for a set of loads and compression ratios (CR). The experimental observations show that 5% water in POME produce 3.5% lower brake thermal efficiency and 11% higher brake specific fuel consumption as compared to baseline diesel. Furthermore, the exhaust gas temperature and other emissions like oxides of carbon, oxides of nitrogen and hydrocarbon for the emulsified POME are found to be lower than the baseline diesel.

Performance and exhaust emission studies of Waste Chicken Oil Methyl Ester (WCOME)-diesel fuel blends has been presented in this paper. The production of biodiesel from waste chicken oil was carried out via transesterification method. Blending ratios were preferred as 5% (B5), 10% (B10), 25% (B25) and 50% (B50) respectively. Performance and emission studies were carried out in a commercial diesel engine. The performance results reveal that blends of WCOME with diesel fuel provide increase on the brake specific fuel consumption (bsfc) and decrease on the brake power output proportional to the reduction in the heating value of blends. As a result, while the carbon monoxide (CO) and the carbon dioxide (CO2) emissions were reduced, nitrogen oxides (NOx) emissions were stated higher compared with the diesel fuel emission characteristics.
