Abstract

This studies proposes the effect of variations concentration of cajupuut oil and magnetic field of attraction on internal combustion engine performance and flue gas emissions. The increasing demand for petroleum energy is increasing, in line with the rising levels of flue gas emissions produced using transportation and the industrial world. Therefore, environmentally friendly alternative fuels are needed. Because the availability of fossil fuels cannot be renewed and their existence is increasingly depleting. This problems can overcome by saving fuels consumption. One way to save fuels are by adding bio-additives from cajupuut oil and a magnetic field to the fuel line. This research uses a direct test method using tools like a chassis dynamometer and gas analyzer. Pertalite fuel is mixed with various concentrations of cajupuut oil, six cc, eight cc, and ten cc and with addition of a magnetic fields strength of 10,000 Gauss of the genio motorcycle fuel line. This research has found that influence of variation of concentration in cajupuut oil and the magnetic field of attraction significantly impact engine performance and flue gas emissions. A mixture of eucalyptus ten ml with a magnetic field of attraction produces the highest maximum power and torque of 8.35 Hp and 11.77 Nm, respectively. Meanwhile, CO emissions have a level of 0.1%, but the highest CO2 level is 9.6% compared to other concentrations.

Abstract

Many researchers have introduced nanolubricants in the field of refrigeration systems to improve performance. Nevertheless, academic literature lacks comprehensive explanations of the impact of nanoparticles on the physical phenomena that influence the refrigeration system. Several factors such as stability, agglomeration, and distribution can significantly affect the sustainability of performance. Hence, this work provides an analysis of the methods using nanolubricants to improve the performance of refrigeration systems. This study provides a comprehensive analysis of the performance parameters of the refrigeration system, including compressor work and coefficient of performance (COP), when utilizing nanolubricants. The study findings suggest that including nanolubricants in the refrigeration system can enhance the heat transfer coefficient. Hence, nanolubricants are identified as the most promising contenders for enhancing the efficiency of the refrigeration system.
