“…The increase in the engine efficiency was also shown to be a function of the valve timing and valve lift profiles in addition to optimisation of intake geometry to eliminate excessive backflow. A important aspect for engine intake geometry was highlighted by S.A. Sulaiman et al on the experimental research on intake geometry of a Go-kart engine [6]. According to their results, the variation in the intake manifold did not produce a significant impact on the engine performance at low valve lifts.…”

“…Generally, when a velocity stack is used on an engine, an air filter is not used. To minimise flow resistance, the outlet pipe, which is the inlet to the intake manifold should have no sharp bends and the interior wall surface should be smooth [14]. Giannakopoulos, Frouzakis [15] studied the incompressible flow in the intake pipe of an internal combustion engine.…”

Induction system or also known as the breathing system is a sub-component of the internal combustion system that supplies clean air for the combustion process. A good design of the induction system would be able to supply the air with adequate pressure, temperature and density for the combustion process to optimizing the engine performance. The induction system has an internal flow problem with a geometry that has rapid expansion or diverging and converging sections that may lead to sudden acceleration and deceleration of flow, flow separation and cause excessive turbulent fluctuation in the system. The aerodynamic performance of these induction systems influences the pressure drop effect and thus the engine performance. Therefore, in this work, the aerodynamics of motorcycle induction systems is to be investigated for a range of Cubic Feet per Minute (CFM). A three-dimensional simulation of the flow inside a generic 4-stroke motorcycle airbox were done using Reynolds-Averaged Navier Stokes (RANS) Computational Fluid Dynamics (CFD) solver in ANSYS Fluent version 11. The simulation results are validated by an experimental study performed using a flow bench. The study shows that the difference of the validation is 1.54% in average at the total pressure outlet. A potential improvement to the system have been observed and can be done to suit motorsports applications.

In the recent era, energy is more preferred to be produced from renewable energy resources rather than from non-renewable resources. Both non-renewable and renewable energy resources have their own limitations such as the set up cost for renewable is high whereas pollution from non-renewable is high. Based on the limitations, researchers focused on the emission control in automobiles rather than using non-renewable sources. This forms the major objective for the engine designers to achieve lowest possible emission level with efficient combustion. Studies on emission level reduction shows that the flow harnessing in the intake manifold of IC engine can yield improvement in engine torque up to 10% along with a nominal decrease in emission level. The researches reveal that the optimization of an intake manifold plays an important role in manifold design to maximize the mass of air inducted into the cylinder for efficient combustion. Traditional manufacturing of intake manifolds and the trial and error method to select an optimized manifold is time-consuming and cost-effective. This work focuses on the design of an intake manifold withthe different configuration such as normal, convergent and venture types and the study of the airflow through each designed manifolds has been performed using CFD. On comparison of the analysis results, an optimized intake manifold which allows maximum air flow inside the cylinder has been selected for efficient combustion.
