Background: It is a product-oriented breakthrough in technological research carried out for the following reasons: Each year, India imports more than Five lakh crore rupees (INR) worth of fuel, with commercial vehicles roughly using 4 lakh crore rupees worth of diesel. The engines of these vehicles are water-cooled, which keeps the temperature of the engine materials below 100 o C. The temperature of the material must remain below 100 o C for the reasons listed below. If the temperature in the cylinder surpasses 100 • C, the water in the radiator will boil. When the temperature rises over 140 o C, the liquid lubricant becomes charred and sticky and seizes the engine. Hence, if liquid oil is used, a radiator has to be utilised, and in that case, heat loss to the surroundings through the radiator is between 30 and 40% of the diesel equivalent. Objectives: To draw performance curves for the proposed modified single cylinder and to do thermal and design calculations. An engine of the single-cylinder category and diesel run by diesel in the design stage of conversion to drastically improve efficiency. Methods: In a stainless steel cylinder, a stainless steel piston is installed over a conventional piston, and the firing is transferred to the stainless steel piston, which lacks piston rings. Only a close gap is maintained between the stainless steel cylinder and the stainless steel piston, as no liquid lubricant is used, and the radiator can be eliminated. Fabrication drawings for the proposed modification of the singlecylinder diesel engine are made using AutoCAD to improve efficiency by adding two attachments. Thermal calculations are performed using fundamental equations, and performance curves are then generated and analysed. 3D modelling is carried out for the piston and cylinder independently using Autodesk Inventor. ANSYS software is used to get temperatures in selected regions and calculate heat loss from the hot piston bottom. A rigorous theoretical analysis was conducted on the proposed modification planned for optimum performance. Findings: The thermal performance calculations were made for various load conditions, viz.,

“…Researchers and engineers have recently paid more attention to modular buildings' IMCs. Extensive state-of-the-art literature studies on the structural performance of IMCs were conducted in [8,11,14,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. While the internal area between the adjacent modules is still the most prone, various (internal) inter-module connection techniques have been proposed in the available literature that aim for easy and fast installations using bolted shear keys, plates, grouts, etc.…”

Interlocking Inter-Module Connections (IMCs) in Modular Steel Buildings (MSBs) have garnered significant interest from researchers. Despite this, the optimisation of plate thicknesses in such structures has yet to be extensively explored in the existing literature. Therefore, this paper focuses on optimising the thickness of interlocking IMCs in MSBs by leveraging established experimental and numerical simulation methodologies. The study developed various numerical models for IMCs with plate thicknesses of 4 mm, 6 mm, 10 mm, and 12 mm, all subjected to compression loading conditions. The novelty of this study lies in its comprehensive parametric analysis, which evaluates the slip prediction model. A random forest regression model, trained using the ‘TreeBagger’ function, was also implemented to predict slip values based on applied force. Sensitivity analysis and comparisons with alternative methods underscored the reliability and applicability of the findings. The results indicate that a plate thickness of 11.03 mm is optimal for interlocking IMCs in MSBs, achieving up to 8.08% in material cost reductions while increasing deformation resistance by up to 50.75%. The ‘TreeBagger’ random forest regression significantly enhanced slip prediction accuracy by up to 7% at higher force levels.
