Abstract

Biofuels include energy-enriched chemicals produced directly through biological processes or derived from the chemical conversion of the biomass of previously living organisms. Biofuels can be classified into two categories: primary and secondary biofuels. The main biofuels are produced directly from burning woody plant material or cellulose and dry animal dung. Secondary biofuels can be classified into three generations, and each is produced indirectly from plant and animal materials. The first-generation biofuel is ethanol derived from starch-rich food crops or biodiesel, extracted from animal fat wastes such as cooking oil. The second generation is bioethanol derived from non-food cellulosic biomass and biodiesel derived from oil-rich plant seeds such as soybean or jatropha. The third generation is a biofuel produced from cyanobacteria, microalgae, and other microbes, which is the most promising approach to meet global energy demand. This community service aims to explain innovation and provide knowledge to technology players, namely technicians, operators, supervisors, and workshop supervisors, about the use of alternative fuels of sesame oil for small-capacity automatic gasoline engines. The counseling results show that the performance and exhaust gas results are optimal so that the technology actors know the quality and quantity of the alternative energy.

Abstract

Alternative fuels such as Methanol-Butanol-Etanol (MBE) are worthy of development because of their optimal characteristics in SI engines. Selective government regulations on vehicle emissions require a shift to environmentally friendly innovative energy. Fuel-containing alcohol has been proven to reduce pollution levels in vehicles optimally. This research has explored MBE fuel mixtures with three variants through experimental methods. Variations MBE1, MBE2 and MBE3 were mixed with gasoline (RON-90) with capacities (5:2:1, 8:4:1, and 10:6:1)v/v when tested using a dyno test on an SI engine automatic type compression ratio 10:1 with a speed gap of 4000-9000rpm. During testing, torque and Mep experienced an optimal increase in MBE3 fuel of 10.78% and 10.55% compared to commercial fuel (RON-90). Engine power and thermal efficiency increased respectively by 10.03% and 10.69%. This condition is inversely proportional to SFC, which decreased by 21.05%. Furthermore, CO and HC exhaust emissions decreased by 12.12% and 4.60% respectively. This phenomenon shows that MBE fuel shows environmentally friendly performance and exhaust emissions for SI engines in daily activities.

Abstract

Injection molding has become a significant manufacturing technique in producing complex polymer components. Its molding efficiency depends on various process and machine parameters, which determine the quality of the final product in terms of various output responses. It is important to state that proper optimization of different input parameters is essential to achieve the desired quality index. This article presents a review of various techniques used so far to optimize various injection molding parameters, along with their advantages and limitations. It is found in the review that a brilliant technique that can be operated without human intervention has not been developed. The design of the injection machine uses a small scale between 75 gr to 150 gr with a heating variation ranging from 200 0C to 250 0C. When testing the tool, it showed that to achieve the optimal final result of a product, it takes 228 seconds at a hot temperature of 200 0C; if the temperature is increased to 225 0C, it takes 217 seconds, and if it is increased to 250 0C, it takes a shorter time of 208 seconds.

Abstract

Butanol as a fuel has a high oxygen content, so the combustion process will be more friendly to the environment. In this study, butanol will be mixed with RON-90 gasoline with a capacity of 5% (B5); 7%(B7); 10%(B10); 12%(B12); 15%(B15) and 18%(B18). The engine used is an automatic transmission with a capacity of 109.5cc with a compression ratio of 9.5:1. The test equipment for engine performance and exhaust emissions is the 50L BRT Super-Dyno and EPSG4 Gas Analyzer. The results showed that using B18 fuel for CO exhaust emissions decreased by 44% at an engine speed of 6000rpm. CO2 exhaust emissions have decreased by 47% at 8000rpm engine speed. HC exhaust emissions have decreased by 28% at 9000rpm engine speed. In contrast to NOx emissions, which increased by 22% at 9000rpm engine speed, this was due to the increasing temperature in the combustion chamber.
