The design of the cylinder head significantly influences the engine’s performance and efficiency,
according to the study by (Johnson et al., 2019), optimizing the combustion chamber shape, valve
geometry, and port design can enhance airflow, increase volumetric efficiency, and improve power
output.
Piston design plays a vital role in engine performance, combustion efficiency, and durability.
Research by (Chen and Liu., 2017) emphasizes the importance of optimizing piston geometry, such
as crown shape, skirt design, and piston ring configuration, to minimize friction, maximize power
transfer, and enhance engine efficiency.
The design of the connecting rod is critical in transmitting power from the piston to the
crankshaft. (Zhang et al., 2018) emphasizes the significance of optimizing the connecting rod’s
geometry and material selection to ensure sufficient strength, stiffness, and fatigue resistance.
The crankshaft design significantly impacts the engine’s rotational balance, stiffness, and overall
performance. Research by Wang and Li (2016) discusses the optimization of crankshaft parameters,
including journal diameter, fillet radius, and counterweight design, to reduce stress concentrations
and improve dynamic balance.
Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) simulations have
become invaluable tools for analysing and optimizing race car engine components. (Patel et al.,
2019) demonstrates the application of FEA in evaluating stress distribution, deformation, and failure
modes of engine components under various operating conditions.
