Abstract:
An air intake system must satisfy three main functions: air filtration, air delivery to the engine and the minimization of orifice noise emission. At the same time, however, the intake system must satisfy the packaging conditions in the engine compartment. The same applies to the exhaust system, with the exception of the filtration function.By determining the noise emission of the source compressor through computer simulation, we were able to optimize the intake and exhaust system. The result was a noise reduction of 25dB[A]. This is sufficient for a passenger car application. As opposed to the intake system, however, the exhaust system has the problem of a high accumulation of water, which requires a drain system.Plastic is an ideal material for the mass production of air and exhaust systems in fuel cell engines for passenger car applications.
