    The effect of the modified intake port with various inclined nozzle angles such as 30 degrees, 60 degrees, and 90 degrees on the diesel engine characteristics when operated with pine oil-diesel blends is investigated. Prior to the engine experimental study, a computational analysis was performed to investigate the impact produced on the flow field parameters of an engine due to modified intake port design. The numerical study revealed increased swirl velocity and turbulence for intake port with a 60 degrees single-pass configuration compared to other design configurations. With evidence of improved swirl velocity and the proposed modified intake port design from the numerical study, an experimental investigation was performed using pine oil blends in the diesel engine with modified intake port configurations. The preliminary engine test findings with standard intake port design indicated that P50 (50% pine oil + 50% diesel) has higher peak engine cylinder pressure and heat release rates than P10 (10% pine oil + 90% diesel). Additionally, the 60 degrees single-pass configuration showed further increase in peak pressure and peak heat release followed by standard and other intake port design configurations. At high load, the P50 blend showed a 12.3% increase in BTE for 60 degrees intake port design configuration in comparison to the standard design configuration. While for the same blend, the engine out emissions like hydrocarbon (HC) and smoke were reduced by about 6.6% and 17.6%, respectively, and nitrogen oxide (NOX) emission was increased by 29% for the 60 degrees single-pass configuration when compared to the standard design configuration. Overall, the intended intake port design modification strategy increased the swirl velocity and turbulence, which improved the air/fuel mixing and combustion. This study identifies 60 degrees single-pass configuration as an optimum design on account of the aforementioned improved engine combustion, performance, and emissions.

    Production of Raphanus Sativus Biodiesel and Its Performance Assessment in a Thermal Barrier-Coated Agriculture Sector Diesel Engine
    (Wiley-V C H Verlag Gmbh, 2023) Ravikumar, Venkatachalam; Senthilkumar, Duraisamy; Vellaiyan, Suresh; Saravanan, Chidambaram Ganapathy; Vikneswaran, Malaiperumal; Bai, Femilda Josephin Joseph Shobana; Varuvel, Edwin Geo
    Herein, in order to estimate the optimized process specifications, an empirical study is done for biodiesel production, performance of standard and coated engine, combustion, and discharge aspects of Raphanus sativus (radish) biodiesel. Optimization process parameters of biodiesel production are done using the response surface method. The importance of this study is that optimized biodiesel production is used to improve the biodiesel properties and fatty acid content to find suitable vegetable oil as well as a new coating material for sustainable development of the country in the field of agriculture and ecological conditions. The mechanism used in this research work is a coating for internal combustion engine components done with partially stabilized zirconia, aluminum-20% silicon carbide (Al-20%SiC), and titanium dioxide that acts as a ceramic composite settled above the coating that has a thickness of 450 mu m by the technique called air plasma spray for test purpose. To increase the performance of an engine and reduce the emission particles like smoke density, carbon monoxide, and hydrocarbon except NOx, the partially stabilized zirconia, aluminum-20% silicon carbide (Al-20%SiC) coated engine is used under various compositions of radish biodiesel and clean diesel. To reduce NOx, the engine operation is carried out along with the TiO2 coated combustion chamber steam, and water injection technique is added to overcome the NOx formation. From this study, the resulting factor shows that adding 25% radish biodiesel (B25) and 75% clean diesel shows a reasonable reduction in emissions with comparatively better performance and combustion in the engine under consideration.
