Thermal fatigue test stand for combustion engine cylinder heads

摘要

Test stand comprises a support (14) for a cylinder head (C) having one or more cylinder head areas exposed to combustion under normal engine operating conditions, a burner (11) that is arranged to direct a flame at said area and a thermal flux sensor (171) placed in the cylinder head at the same level as the heated zone to check that the heat flux is as predetermined. Independent claims are made for a calibration and test procedure for using the cylinder head test bank.
