This article aims to study the impact of camphor oil premixing with intake air on compression ignition (CI) engine characteristics powered with jatropha oil and cottonseed oil. The experiment is conducted on the direct injection compression engine attached to the premixing setup. The investigation reveals that premixing of camphor oil with cottonseed oil and jatropha oil escalates the thermal brake efficiency to 35.02% and 33.62% and brings down the brake‐specific energy consumption to 10.27 and 10.70 kJ kWh−1. At all loading conditions, the premixing of camphor oil and the rise of camphor oil in premixing proportions increase the volumetric efficiency and cut the exhaust gas temperature. 20% premixing of camphor oil with cottonseed oil and jatropha oil drops the smoke opacity emissions by 22.23% and 11.86% and NO emission by 23.27% and 14.59%, respectively, at full load conditions. Further, it shows a 27.60% and 21.14% hike in CO emissions and a 31.34% and 31.87% hike in HC emissions at full load conditions. The in‐cylinder pressure, heat release rate, and mean gas temperature increase with increasing the energy share of camphor oil in premixing. Overall, the premixing of camphor oil shows better CI engine attributes except HC and CO emissions.

“…Hence, an exergy destruction term should be added to exergy balance of a system [15] . The exergy (availability) can be described as the maximum theoretical useful work in a thermodynamic system since the system is brought to full thermodynamic equilibrium with the environment when the system only interacts with that environment [38] . The exergy balance for steady state systems is expressed using Eq.…”

The effective management of waste tires poses a critical and urgent challenge in today's environmental landscape. These discarded tires endure an astonishing degradation period of approximately 600 years, emphasizing the need to urgently adopt techniques that expedite this process in an environmentally responsible manner to protect our planet. Tackling this issue involves exploring the conversion of waste tires into diesel fuel, a promising solution to mitigate the problem. Achieving sustainable progress requires a keen focus on the energy and exergy efficiency of systems, crucial aspects in this endeavor. Therefore, this study is dedicated to a comprehensive and sustainable assessment that compares conventional petroleum-derived diesel (diesel oil) with pyrolytic oils derived from rubber waste, inoperable tires, and Eucalyptus urograndis wood. These oils are intended for use in compression ignition internal combustion engines. The methodological framework of this work involves an in-depth exploration encompassing energy, exergy, and environmental analyses in a steady-state context. Using the Diesel RK software, combustion is simulated with fuel specifications sourced from established literature. The investigation is conducted within a Scania diesel stationary engine under varying scenarios. First, blends of tire pyrolysis oil (TPO) and diesel are examined, specifically in proportions of 10% TPO and 90% diesel, followed by 20% TPO and 80% diesel. Second, mixtures of Eucalyptus urograndis pyrolytic bio-oil (EPO) at ratios of 10% EPO and 90% diesel, as well as 20% EPO and 80% diesel, are considered. Lastly, the study examines the performance of conventional commercial diesel fuel. Through meticulous analysis, discernible outcomes emerge, revealing the energy and exergy performance characteristics. Notably, the parameters studied indicate a notable resemblance between diesel and TPO10 across all cases, with TPO10 emerging as the frontrunner in these analyses, closely followed by TPO20. Moreover, the study incorporates a sustainability perspective, highlighting opportunities for improvement, ecological metrics, and the emission profile of pollutants.

“…A significant amount of exergetic studies are focused on the analysis of combustion engines where biodiesel is used as fuel to study the behavior of the engines at different mixtures of diesel-biodiesel, which allows the identification of diverse operating parameters [22][23][24]. In general, studies show that energy and exergetic efficiency is higher when using biodiesel as fuel in these engines [25]. Exergy analysis of a transesterification process provides relevant information to reduce irreversibilities and optimize the process in terms of mass and energy.…”

Thermodynamic Analysis of Waste Vegetable Oil Conversion to Biodiesel with Solar Energy

Exergy and energy analyses of two biodiesel production processes that integrate solar energy as the main energy source were developed to determine the process with the higher efficiency from an energy and exergy approach. The biodiesel production processes were simulated in ASPEN PLUS®, and the solar energy supply was studied in TRNSYS®, using EXCEL® simultaneously for the exergetic analysis. The solar thermal energy collection system can supply 81% of the energy required by the alkali process in the Flash separation equipment. For the supercritical process, solar thermal energy can supply 74.5% of the energy in the preheating and separation stages. The energy efficiency of the supercritical process is higher; nevertheless, the exergetic efficiency of the alkaline process is higher than the supercritical one. Solar collection systems contribute from 85% to 93% of the exergy destroyed by the global process for both cases. The alkaline biodiesel production process has the highest advantages when using solar energy as the main source of energy, compared to a process in supercritical conditions that presents greater irreversibilities and requires more infrastructure to collect the solar resource. However, using solar energy as the foremost energy source offers an alternative to fossil fuels, and it provides an environmental benefit concurrently with the use of biodiesel.
