Intake manifold system is one of the important component in the engine system which functions to evenly distribute the air flows into every cylinder of the engine. With the restricted air intake rule regulation, the intake air system for a car must be properly design in order to minimize the performance dropped caused by the restrictor. The paper presents the study on the effects of intake design parameter towards the performance of the engine and then improves the performance of previous intake manifold system. This study starts with the development of Honda CBR 600RR engine model and intake manifold system model using GT-Power engine simulation software to be used for the simulation purposes. After developing the reference engine model, the parametric study was carried out to study the effect of the intake manifold parameter design on the engine performance. The optimization process was then performed to achieve the target of improvement which has already been set prior to performing the optimization. The final results show an increase up to 4.83% and 4.45% of torque and air flow rate respectively at the desired operating range of engine speed.

Intake manifold determines the charge flowing or the mass flow rate of the fuel and air mixture, which greatly influenced the volumetric efficiency of an engine. It has a great impact on engine power and torque. They are greatly affected by degree to which cylinders are charged & geometrical parameters of intake manifold. Every specified engine has its specific engine speed and it can be optimized with the help of the intake manifold geometry. Current work aims to study the effects of various designs of Intake manifolds for a naturally aspirated Royal Enfield EFI500 engine and to increase volumetric efficiency for FSAE related competitions, by doing CFD simulations and tuning of runner length. The objective is to increase the volumetric efficiency of the engine assuming a standard restriction of 20mm diameter to limit the overall power output. After CFD on intake manifold, results obtained in the least pressure drop and hence maximum volumetric efficiency.

In the work, the suitable volumetric efficiency is very important for the gasoline engine to achieve the aim of energy-saving and emission reduction. Thus, the intake system characteristics, such as intake manifold length, diameter, volumetric efficiency, and valve phase, should be investigated in detail. In order to investigate the performance optimization of the engine intake system, an optimization model of the engine intake system is developed by the GT-Power coupled with Matlab-Simulink and validated by the experimental results under the different conditions at full load. The engine power-, torque-, and brake-specific fuel consumption are defined as the result variables of the optimization model, and the length and diameter of the intake manifold are defined as the independent variables of the model. The results show that the length of intake manifold has little influence on the engine power and BSFC, and the length of intake manifold has a great impact on the performance index at high speed. In addition, the engine volumetric efficiency is the highest when the length of intake manifold is in the range of 240 and 250 mm. The engine BSFC improved by variable valve timing is significant compared with the original result. Finally, the improvement suggestions for the performance enhancement of the gasoline engine are proposed.

Air intake system of an internal combustion engine plays main role in delivering fresh air from the environment to the engine and dampening the sound of the engine combustion process coming from the engine combustion process. In this study, a simulation was conducted to improve the existing air intake system design in terms of acoustic study to have better sound quality by modifying the resonators, air duct and airbox volume of the air intake module.

High Influence

Fuel price crisis has caused people to demand a car that is having a low fuel consumption without compromising the engine performance. Designing a naturally aspirated engine which can enhance engine performance and fuel efficiency requires optimisation processes on air intake system components. Hence, this study intends to carry out the optimisation process on the air intake system and airbox geometry. The parameters that have high influence on the design of an airbox geometry was determined by using AVL Boost software which simulated the automobile engine. The optimisation of the parameters was done by using Design Expert which adopted the Box-Behnken analysis technique. The result that was obtained from the study are optimised diameter of inlet/snorkel, volume of airbox, diameter of throttle body and length of intake runner are 81.07 mm, 1.04 L, 44.63 mm and 425 mm, respectively. By using these parameters values, the maximum engine performance and minimum fuel consumption are 93.3732 Nm and 21.3695×10-4 kg/s, respectively. This study has fully accomplished its aim to determine the significant parameters that influenced the performance of airbox and optimised the parameters so that a high engine performance and fuel efficiency can be produced. The success of this study can contribute to a better design of an airbox.
