Sampling Flow Channel Design in Automobile Engine Intake Manifold

Abstract:

As a result of turbulence and wide flow velocity range, flow velocity in engine intake manifold cannot be tested directly by using a thermal flow sensor. In this study, a sampling flow channel is designed according to the testing conditions and range of the thermal flow sensor. The flow velocity in the whole intake manifold was simulated by the finite element method software program. was found proportional to , and slope K was constant. ranged from 0 m/s to 4.8 m/s at the suitable outlet position of the sampling flow channel, which could be tested for the thermal flow sensor. The mass flow intake manifold was obtained by testing the mean flow velocity in the test section of the sampling flow channel .
