Abstract: (524 Views)
The task of the intake air manifold of gasoline engines is to transfer air, crankcase vapors, blow-by flow, fuel tank vapors, and fuel injected into the passages of the engine cylinder head. This part must be designed in such a way that it can supply the air needed by the car engine in different conditions of its operation with the lowest pressure drop and speed and distribute it equally between the engine cylinders in terms of flow rate and air-fuel ratio. Also, the mixing of oil vapors, blow-by flow and gasoline vapors of the engine is done in it and distributed equally between different cylinders. To achieve this goal, the air manifold needs to be designed in the most optimal way. In this research, the EC5 engine has been examined. The intended engine is designed and simulated in GT-SUITE software and the desired information for this modeling is practically extracted. The model designed in the software has been validated using experimental results. Then, using the desired model, the resonance volume in the air manifold has been investigated. Two engine models have been designed and compared using resonant volume and without using resonant volume in the inlet air manifold. The results of this comparison show that the engine with resonance volume had an increase in power of about 10 kW at engine speed of 6000 rpm
