Numerical investigation and experimental analysis of nanoparticles modified unique waste cooking oil biodiesel fueled C. I. Engine using single zone thermodynamic model for sustainable development

Abstract

This study investigates the experimental and theoretical impact of biodiesel obtained from hydrodynamic cavitation based waste cooking oil on the performance parameters while testing compression ignition engines. Due to the alarming energy security concerns and inadequacy of fossil fuels, biodiesel is seeking importance globally. Many countries have put forth different subsidies, incentives, and mechanisms, urging the usage of biodiesel. In the current research, nanotechnology is effectively used for enhancement of the blend properties of biodiesel, making them more suitable for compression ignition diesel engines. This investigation includes a comparative analysis of diesel to biodiesel blends with and without the addition of nanoparticles CuO and ZnO. To understand the performance characteristics of a four-stroke diesel engine, a single zone thermodynamic model is developed in it. Comparative readings are taken for the test blends with varying compression ratios of 16, 17, and 18. For each ratio, a variation in the cylinder volume is noted with reference to the rotation in the crank angle. The investigated parameters include net heat release, the rate of pressure rise, brake thermal efficiency, and the heat transfer coefficient. This study concluded that the theoretical results are in close consonance with the experimental results of the comparative analysis of diesel and biodiesel blends. Results obtained from this research paper can contribute to predict combustion process analysis and recommend the effectiveness of nano-additives in biodiesel enhancement.

Four-Dimensional Printing of Multifunctional Photocurable Resin Based on Waste Cooking Oil

“…The resource utilization of waste cooking oil (WCO) can effectively alleviate the lack of petroleum resources, reduce environmental pollution, and protect people’s health. , Now, there are varying strategies available to achieve the reutilization of WCO that can provide products such as biofuels (biodiesel, − bioethanol, , and biogas − ), biolubricants, − biosurfactants, alkyd resins, washing products, , and so forth. Among these, the production of biodiesel from WCO has become the mainstream way for WCO utilization because it is more cost-effective than biodiesels made from other natural oil sources, such as palm, soybean, peanut, or olive oil, while its production requires lower energy consumption and emits minimum greenhouse gas. , However, traditional products based on WCO exhibit quite a low-profit margin (often <20%), necessitating a large-scale production line with a sustainable and massive resource supply, which is easily affected by the prices of the raw materials. ,, Thus, the traditional utilization strategy for WCO, such as biodiesel production, is only suitable for large-scale production and requires huge spending on capital, equipment, land, and the workforce in economically strong areas, while a simple, convenient, and low-cost method that could produce WCO-based materials with high technology and added value may be a better choice for WCO utilization in economically underdeveloped areas. , …”

Investigation Of Waste Cooking Oil-Diesel Blend With Copper Oxide Additives As Fuel For Diesel Engine Under Variations In Fuel Injection Pressure

“…The frequent rise in fuel prices leads to higher inflation rates which create a hard time for the common man to face day-to-day economic challenges [1,2]. The primary fuel for the transportation sector is diesel and with a high number of diesel engines running today, researchers have been tasked to find alternate fuel for CI engines [3,4].…”

“…To address this issue, Esterified oils or Biodiesel are blended with diesel fuel and by doing so, the properties of the Esterified oil-diesel blend have in-line fuel properties [13,14]. When these blends are combusted in regular diesel engines, the thermal performance is good and emissions like CO and HC are limited [15,16,[1][2][3]. But the real problem which restricts the use of Blended Diesel-Oil esters is the fuel consumption rate and levels of NOx [17,18].…”
