“…With hydrogen engines, lean mixtures can be ignited quickly due to the lower ignition energy of hydrogen fuel (Ikonnikova et al, 2022;Vichos et al, 2022). One of the most stressed parts of an internal combustion engine is its piston (Ismail et al, 2020;Mancaruso and Sequino, 2019). In addition to being subjected to an excessive amount of thermal stress, the piston in the combustion chamber is exposed to large axial and lateral loads as well as inertia forces during the power cycles (Najafi et al, 2019;Garbinčius et al, 2005).…”

“…To understand the deformed shape of the engine piston and its strength, computerized finite volume analysis techniques were used since they simulate and calculate combined thermal loads due to high gas temperatures and mechanical loads due to high gas pressures on the piston (Ismail et al, 2020;Najafi et al, 2019).…”

“…Under all operating conditions, particularly when there is a large amount of power being output, the piston of the internal combustion engine should possess high strength. Using a numerical model, Ismail et al, (2020) studied the effect on piston loading by increasing the boosting pressure until achieving the maximum engine power possible by analyzing the thermomechanical loads on the whole body of the piston. According to their results, the piston is in a safe condition and can withstand additional stress loads up to the additional power that can reach 56%.…”

Fueling internal combustion engines with hydrogen is one of the most recommended alternative fuels today in order to combat the energy crisis, pollution problems, and climate change. Despite all the advantages of hydrogen fuel, it produces a higher combustion temperature than gasoline. In an internal combustion engine, the piston is among the numerous complex and highly loaded components. Piston surfaces are directly affected by combustion flames, making them critical components of engines. To examine the stress distribution and specify the critical fracture zones in the piston for hydrogen fuel engines, a three-dimensional CFD-solid-mechanics model of the internal combustion engine piston subjected to real thermomechanical loads was analyzed numerically to investigate the distribution of the temperature on the piston body, the interrelated thermomechanical deformations map, and the pattern of the stresses when fueling the engine with hydrogen fuel. With the aid of multiphysics COMSOL software, the CFD-solid-mechanics equations were solved with high accuracy. Despite the increase in pressure on the piston and its temperature when the engine is running on hydrogen fuel, the results show that the hydrogen fuel engine piston can withstand, safely, the thermomechanical loads. In comparison to gasoline fuel, hydrogen fuel caused a deformation of 0.34 mm, an increase of 17%. This deformation is within safe limits, with an average clearance of 0.867 mm between the cylinder liner and piston.

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.
