experimental study of the Performance and Emissions characteristics of fusel oil gasoline blends in spark ignited engine using response surface methodology
Fuel, 2020Co-Authors: Suleyman Simsek, Samet UsluAbstract:Abstract The principal aim of this study is to use fusel oil which is a waste product obtaining as by-product from the ethanol production processes of sugar factories as an alternative energy source to gasoline in a spark ignition (SI) engine. The secondary purpose of this research is to define the optimum operating parameters such as compression ratio (CR), load and fusel oil percentage concerning the Performance and Emissions of SI engine by Response Surface Methodology (RSM). The tests of this research have been performed by several fusel oil–gasoline blends (0% and 30%), various CR (8.00, 8.50 and 9.12) and different engine load (1000, 2000, 3000, 4000, 5000 and 6000-W). According to obtained data from experiments, the RSM optimization is employed to maximize brake thermal efficiency (BTE) and minimize the brake specific fuel consumption (BSFC), nitrogen oxides (NOx), hydrocarbon emission (HC), carbon monoxide (CO) and carbon dioxide (CO2). RSM study showed that, fusel oil percentage of 30% at 8.39 CR and 3777-Watt engine load are the optimum engine operating parameters. Moreover, the optimum responses with a high desirability of 0.7685 were 22.47%, 391.43 g/kWh, 188.86 ppm, 12.46%, 1.78% and 131.91 ppm for BTE, BSFC, NOx, CO2, CO and HC Emissions respectively. The results show that, RSM can help to estimate and optimize the optimum engine working parameters for improved the Performance and Emissions of engine with fewer tests. The outcomes stated future focus of similar research into optimization of fusel oil/gasoline fuel blends.

Comparison of engine Performance and Emissions for petroleum diesel fuel, yellow grease biodiesel, and soybean oil biodiesel
Transactions of the ASAE, 2003Co-Authors: Mustafa Canakci, Jh Van GerpenAbstract:Biodiesel is a non-toxic, biodegradable and renewable alternative fuel\nthat can be used with little or no engine modifications. Biodiesel is\ncurrently expensive but would be more cost effective if it could be\nproduced from low-cost oils (restaurant waste, frying oils, animal\nfats). These low-cost feedstocks are more challenging to process because\nthey contain high levels of free fatty acids. A process for converting\nthese feedstocks to fuel-grade biodiesel has been developed and\ndescribed previously. The objective of this study was to investigate the\neffect of the biodiesel produced from high free fatty acid feedstocks on\nengine Performance and Emissions. Two different biodiesels were prepared\nfrom animal fat-based yellow grease with 9% free fatty acids and from\nsoybean oil. The neat fuels and their 20% blends with No. 2 diesel fuel\nwere studied at steady-state engine operating conditions in a\nfour-cylinder turbocharged diesel engine. Although both biodiesel fuels\nprovided significant reductions in particulates, carbon monoxide, and\nunburned hydrocarbons, the oxides of nitrogen increased by 11% and 13%\nfor the yellow grease methyl ester and soybean oil methyl ester,\nrespectively. The conversion of the biodiesel fuel's energy to work was\nequal to that from diesel fuel.

The neat fuels and their 20% blends with No. 2 diesel fuel were studied at steady-state engine operating conditions in a four-cylinder turbocharged diesel engine. Although both biodiesel fuels provided significant reductions in particulates, carbon monoxide, and unburned hydrocarbons, the oxides of nitrogen increased by 11% and 13% for the yellow grease methyl ester and soybean oil methyl ester, respectively.

Performance and Emissions characteristics of biodiesel from soybean oil
Proceedings of the Institution of Mechanical Engineers Part D: Journal of Automobile Engineering, 2005Co-Authors: Mustafa CanakciAbstract: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.

An extended mean value model (EMVM) for control-oriented modeling of diesel engines transient Performance and Emissions
Fuel, 2015Co-Authors: Kamyar Nikzadfar, Amir H. ShamekhiAbstract:Abstract Utilizing model-based controller design in automotive and powertrain industry is recently attracting more attention due to its benefits in reducing controller development time and cost. Recent automotive emission legislations put more limits on engine Emissions in transients. Hence, the models, which are capable of predicting engine Performance and Emissions in transient, are of the utmost importance. On the other hand, the model-based controller design requires accurate meanwhile fast to run models to be employed in both controller development and subsequent hardware in loop processes. In this paper, a new quasi-static control oriented diesel engine modeling approach is investigated based on the block oriented modeling method to predict the engine behavior in sense of both Performance and Emissions in transient and steady state operation. The accuracy and speed of model execution are two important attributes of models, which are in mutuality. In the proposed modeling a tradeoff between these two factors are made and some solutions are employed to increase both model accuracy and speed. The diesel engines are nonlinear dynamic systems. In the proposed modeling approach, this behavior is assumed to be composed of a semi-static combustion process surrounded by peripheral dynamic processes. This static in cylinder process model is responsible for the Performance and Emissions of the engine. Thermodynamic modeling coupled with chemical reaction model altogether with 1D gas dynamic model is employed to predict the Performance and emission of in-cylinder process based on some boundary conditions which are derived from peripheral systems. Usually an iterative time consuming method is employed to solve the thermodynamic models. In order to decrease the run-time of model, a neural network is trained to mimic the thermodynamic model. On the other hand ordinary time differential equations are used to model the peripheral dynamic systems such as induction and exhaust systems. In order to validate the model for both steady and transient regimes, real step responses as well as experimental frequency response are compared with model results. The comparison of experimental data with model results shows tight agreement in both Performance and emission prediction capabilities.

alternative fuel and gasoline in an si engine a comparative study of Performance and Emissions characteristics
Fuel, 2010Co-Authors: Ali Mohammad Pourkhesalian, Amir H. Shamekhi, Farhad SalimiAbstract:The strict regulation of environmental laws, the price of oil and its restricted resources, has made engine manufacturers use other energy resources instead of oil and its products. Despite the fact that nowadays alternative fuels are not currently widely used in vehicular applications, using these kinds of fuels will be definitely inevitable in the future. In this paper, a computer code is developed in Matlab environment and then its results are validated with experimental data. This simulated engine model could be used as an powerful tool to investigate the Performance and emission of a given SI engine fueled by alternative fuels including hydrogen, propane, methane, ethanol and methanol. Also, the superior of alternative fuels is shown by comparing the Performance and Emissions of alternative fueled engines to those in conventional fueled engines. Eventually, it is concluded that volumetric efficiency of the engine working on hydrogen is the lowest (28% less that gasoline fueled engine), gasoline produce more power than the all being tested alternative fuels and BSFC of methanol is 91% higher than that of gasoline while BSFC of hydrogen is 63% less than gasoline.
