Abstract:
The present work proposes to execute bench test swirl number measurements using a modular
device and cylinder head intake ports from a diesel engine manufactured via additive
manufacturing (AM). Swirl number measurements with intake ports produced by AM, bring
the following advantages: Tests reproducibility, since having the geometric model (CAD) of
tested models is enough to re-build the geometry analyzed in the bench test. Easy to measure
the swirl number variances in consequence of potential manufacturing process deviations and
time reduction to the development of new intake ports geometry. The research is
experimental, one sample of the investigated cylinder head was sent to the Polytechnic School
of Sao Paulo (EPUSP) laboratory, and the swirl number was measured and recorded for later
results comparison with proposed method. This cylinder head sample was then sectioned and
digitalized as to know to have the same internal geometry in the intake ports produced via
AM. All tests were performed in the same rig and with the same control system aiming to
reduce the external variables during data acquisition. When the swirl number results between
the complete cylinder head and modular device using AM were compared, no statistically
significant changes were found. (p. 235-251 . In: . São Paulo: Blucher, 2017. - ISSN 2357-7592, DOI 10.5151/engpro-simea2017-18)
