Comprehensive Study on the Effect of CuO Nano Fluids Prepared Using One-Step Chemical Synthesis Method on the Behavior of Waste Cooking Oil Biodiesel in Compression Ignition Engine

Abstract

Vegetable oil is considered as one among the promising alternatives for diesel fuel as it holds properties very close to diesel fuel. However, straight usage of vegetable oil in compression ignition (CI) engine resulted in inferior performance and emission behavior. This can be improved by modifying the straight vegetable oil into its esters, emulsion, and using them as a fuel in CI engine showcased an improved engine behavior. Waste cooking oil (WCO) is one such kind of vegetable oil gained a lot of attraction globally as it is generated in a large quantity locally. The present investigation aims at analyzing various parameters of single cylinder four stroke CI engine fueled with waste cooking oil biodiesel (WCOB), waste cooking oil biodiesel water emulsion (WCOBE) while the engine is operated with a constant speed of 1500 rpm. Furthermore, an attempt is made to study the impact of nanofluids in the behavior of the engine fueled with WCOB blended with nanofluids (WCOBN50). This work also explored a novel method of producing nanofluids using one-step chemical synthesis method. Copper oxide (CuO) nanofluids were prepared by the above mentioned method and blended with waste cooking oil biodiesel (WCOBN50) using ethylene glycol as a suitable emulsifier. Results revealed that brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) of WCOBN50 are significantly improved when compared to WCOB and WCOBE. Furthermore, a higher reduction in oxides of nitrogen (NOx), carbon monoxide (CO), hydrocarbon (HC), and smoke emissions were observed with WCOBN50 on comparison with all other tested fuels at different power outputs. It is also identified that one-step chemical synthesis method is a promising technique for preparing nanofluids with a high range of stability.

Alternativas De Melhoria Da Qualidade Nos Processos De Um Restaurante Sob a Ótica Das Práticas Sustentáveis

“…Como sugestão para estudos futuros, cita-se a utilização de modelos de simulação para verificar o impacto gerado com a aplicação da alternativa priorizada e ainda um estudo que verse a respeito da destinação dos resíduos gerados pela organização. Pois estudos recentes têm demonstrado que muitos resíduos advindos até mesmo de restaurantes podem ser potenciais alternativas, como no caso do óleo de cozinha usado, que pode ser matéria prima para fabricação de biodiesel (Bechet et al, 2010;Demirbas, 2009;Zhang & Kong, 2010;Mendes, 2015;Aboelazayem, Gadalla & Saha, 2019;Aghel et al, 2019;Ahmad et al, 2019;Nabi et al, 2019;Velmurugan et al, 2019;Tan et al, 2019;Mohadesi et al, 2019;Dimitriou, Tsujimura & Suzuki, 2019).…”

Computational simulation and evaluation of the use of cooking oil for biodiesel generation in municipalities of southern Brazil

“…According to Mendes (2015), biodiesel production is mainly carried out by vegetable oils available internally in producing countries, most of which are in excess of the food industry. Several studies have analyzed the use of cooking oil in biodiesel production (Bechetet al, 2010;Demirbas, 2009;Mendes, 2015;Zang and Kong, 2010;KANNENGIESSER et al, 2016;ABOELAZAYEM;GADALLA;SAHA, 2019;AGHEL et al, 2019;AHMAD et al, 2019;NABI et al, 2019;VELMURUGAN et al, 2019;TAN et al, 2019;MOHADESI et al, 2019). More details on this production mode will be explained in the following session.…”

“…30 A modied common rail direct injection (CRDI) diesel engine's performance and emission characteristics when running on Ricinus communis biodiesel (RCME20), diesel (80%), and their mixes with strontium-zinc oxide (Sr@ZnO) nanoparticle additions have been tested. 31 A thorough analysis of the literature reveals that most alternative fuels such as biooil, natural gas, waste cooking oils, vegetable oils, and producer gas have been researched in CI engines with different fuel modes, illustrating engine combustion, performance, and emission characteristics as well as usage of numerous optimization techniques toward improvement in overall performance. Bioethanol is another widely used alternative fuel produced from large renewable energy sources such as starch, sugarcane, corn, cellulose, beet, and molasses.…”
