Analysis of emission gas and fuel consumption on SI engine fueled with low-grade bioethanol and oxygenated cycloheptanol additive

Abstract

Abstract. The use of alternative energy source is expected to reduce fossil energy consumption and exhaust emissions. One of the non-fossil energy alternatives introduced for vehicles is bioethanol, it can produce in a simple way and cheap. Low-grade bioethanol has characteristics that depend on exhaust emissions generated. Low-grade bioethanol can be used as a substitute or mixture of fuel. The mixture of bioethanol and gasoline gives an effect to the increase of octane number and reduces the emission of CO2 produces. To get a more optimum effect on fuel consumption and emission, the oxygenated additive can be added to the fuel mixture. In this study, the effect of fuel consumption and emission was carried out by comparison of E5, E10, E15 without additive and with additive oxygenated cycloheptanol. The test will be performed by the method of calculating the amount of fuel consumption against the time to get specific fuel consumption. Emission test will be performed in single cylinder spark-ignition (SI) engine 150cc premix fuel with 100% opening throttle position connected to the gas analyzer in variation speed engine to see the emission gas. This study aims to obtain reduce the emission gas (CO2 and CO) and fuel consumption with the addition of the oxygenated additive. IntroductionThe limited resources of fossil energy and the increasing need for fuel causes the necessity to finding another renewable energy source [1]. In addition, the increased fuel consumption that occurs today will cause the amount of exhaust emission generated increased and this will have an adverse impact on the environmental. Because of that problem, the use of regenerative fuels has been developed lately [2, 3]. By utilizing alternative energy that is environmentally friendly and widely available in nature is expected to be a solution that addresses current problems. One of the alternative energy developed today is biofuel. Biofuel can be used as a substitute for fuel or mixture on fuel [4]. Biofuel consists of several types including bioethanol, biodiesel, biobutanol, bio-methanol, biogas, biohydrogen, and vegetable oil. Currently, bioethanol and biodiesel are being developed to be used as fuel for the future.Bioethanol is one of the renewable fuel sources derived from biomass product. Bioethanol is widely produced from agricultural residue (such as bagasse, rice straw, corn straw, and wheat straw), industrial waste starch processing and lignocellulosic biomass (such as agricultural residues, woody biomass, algae, and industrial solid waste). Indonesia is a country that has abundant raw materials in the manufacture of bioethanol. Looking for the raw material is widely available, bioethanol can be produced on a large scale [5,6].

Utilization Analysis of Bioethanol (Low Grade) and Oxygenated Additive to COV and Gas Emissions on SI Engine

“…In the previous research, the distillation of low-grade bioethanol with compact distillator was experimented 6) up to the analysis of emission gas and fuel consumption on the SI engine fueled with low-grade bioethanol and oxygenated additive was discussed 13) . In this research, the authors checked further to analyze the characteristic of ethanol blend and oxygenated additive for COV IMEP and exhaust gas emissions of various fuel mixture as well as COV IMEP correlation with exhaust gas emissions at variable engine speed were investigated.…”

Liquid biofuel powering the sustainable transport with a low-carbon emission: a review

“…Compared to conventional ethanol-gasoline blends, the introduction of additives arises concerns about their lack-of studied emission profiles and impacts on health and the environment. Studies have shown that oxygenated additives are expected to have reduced toxicity from the emissions [107]. Due to the engine fuel change, the car starting performance, dynamic performance, fuel economic performance, emissions performance, material compatibility performance, and the whole system has changed, which can be enhanced by optimizing the structure of the fuel injector to the fuel and air atomization and mixing, improve engine starting performance [108].…”
