“…On the other side, many scholars attributed that downsize engine still have many areas to research and develop which not only improve the thermal and mechanical efficiency but also pace to the better mechanical and thermal stresses generated inside the combustion chamber when only geometric dimensions reduced in downsized engine. As [1] research results show the increment by 41.7% in the translation vector displacement in downsized engine piston then the normal one. The values of Huber-Mises stresses increased by 35.9% and the highest stress values were recorded near the second sealing ring.…”

This work is highlighting the previous research work on the mechanical and thermal issues in the Downsize Engine. By using downsize engine technology, the consumption of fuel and emission decreased by reducing geometrical dimensions of combustion chamber parts and thermal and mechanical efficiencies increased by increasing the power output bywith the help pg using turbochargers. Using turbochargers, a super knock could result from the pre-ignition and induces severe oscillation and leads to the thermal and mechanical stresses on account of diminished mass and geometrical aspects of the various parts employed in the combustion chamber (CC). The increment in thermal and mechanical stresses may damage the main part(s) (piston) of the combustion chamber. In focusing the above facts; the shape design and the best material is the right choice for the better combustion and long life of the CC parts (piston) in downsizing engine respectively.

The piston material choice is a major factor in the design stages of internal combustion engines for its importance to improving the durability and the operation reliability during the piston life cycle. Indeed, even as many researches have been conducted for a long time to improve the piston performances in the diesel engine, considerable numbers of piston damages still significantly occur. This research work is an assessment by the finite element method (FEM) of a set of piston materials for the purpose of being used in a direct injection diesel engine. The main objective is to predict stresses concentrations and the clearance between the piston and the cylinder (to avoid metal-metal adhesion) from thermomechanical solicitations. The stresses and deformations are evaluated in a 3D piston model by using ABAQUS software. A first assessment step is performed in heat convection/conduction modes to determine the temperature distribution. Then, this last one is coupled to the pressure field resulting from the gas combustion in order to compute stresses and the magnitude displacement. The obtained results show that the austenitic steel AS12UNG with fibre-reinforced possess low thermomechanical stress values compared to other material types. This material allows a minimum failure risk and therefore contributes to the enhancement of the piston design.

This research introduces a method to model the operation of internal combustion engines in order to analyze the forces on the rod, crankshaft, and piston of the test engine. To complete this research, an experiment was conducted to measure the in-cylinder pressure profile. In addition, this research also modelled the friction forces caused by the piston and piston-ring movements inside the cylinder for calculating the net forces experienced by the test engine. The results showed that the net forces change according to the crank angle and reach a maximum value near the top dead center. Consequently, we needed to concentrate on analyzing the stress of the crankshaft, rod, and piston at these positions. The research results are the foundation for optimizing the design of these components and provide a method for extending the operating lifetime of internal combustion engines in real operating experiments.
