The In-Wheel Motor represents a non-conventional propulsion architecture in which the electric motor is integrated into the wheel, offering advantages such as improved energy efficiency, individual torque control, and drivetrain simplification. In this study, two architectures, inboard and outboard, were developed using an original three-dimensional motor–brake–suspension–steering assembly model, in which disk brake position and In-Wheel Motor integration act as primary design drivers influencing vehicle dynamics. Both architectures were developed in CATIA V5 and exported to Altair Motion 2025 for multibody dynamics simulations. The study evaluates the impact of inboard versus outboard disk brake positioning on vehicle dynamics and provides a qualitative assessment of the associated architectures in terms of mechanical complexity, serviceability, sealing requirements, bearing load asymmetry, and packaging constraints. The results indicate that the inboard architecture exhibits more linear and stable kinematics and compliance (K&C) behavior compared to the outboard configuration, at the expense of increased mechanical complexity and reduced serviceability. By contrast, the outboard architecture preserves a simpler, more conventional MacPherson-like layout with a lower component count and improved service access but is dynamically outperformed under the imposed geometric constraints of the present study.

The transformation of chemical energy of the fuel into mechanical energy, through the heat emitted during its burning is accompanied by losses. These losses are manifested, in general, as the amount of heat. They are mainly found in combustion gases and in the cooling fluid.

The air-fuel mixture inlet during the admission stroke and also the discharge of the exhaust gas through the exhaustion, in the process of gas change, influences directly the power and the engine efficiency. During this study, we will analysis the conditions of the intake deployment, especially from a thermal point of view, highlights influences with various implications. Thereby, influence of the thermal regime of the engine concerning the filling highlights how the heating of the air-fuel mixture affects negatively the filling by reducing the filling coefficient values, η_v. Based on the aspects of the analysis in the model developed by the authors, expressed as a distinct function of the degree of filling depending on the temperature of the charge air at the end of the intake process and further increase the temperature of the charge air during the intake process, due to the contact with the warm surfaces of the engine. The model ensures significant results that can be used to improve the performance of the spark ignition engine.

In this paper, it is in focus an analysis and a theoretical study which will develop a mathematical model that will highlight the influences of the thermal regime of a spark plug engine regarding the engine performance improvement.

The continuous rush for development has led the world of automotive engineering to progress that seemed unimaginable just a few years ago. This research paper examined the impact of a topological optimisation of an internal combustion engine block. Starting with the initial conditions, a constraint and load case scenario was established, after which a FEA simulation was conducted to set the reference values. In the last part of the research paper, test results are head-to-head compared to determine and quantify the improvements. This study aims to reduce the volume of the optimised part and increase its overall rigidity. The topology optimisation process represents a good solution for “what if” scenarios. By varying optimisation constraints, the designers can quickly check if the mass reduction of the analysed part is worth the changes.
