    摘要: A test stand for cylinder head components of an internal combustion engine includes at least one combustion or pressure chamber. The test stand supplies a hydraulic fluid to the chamber, and controls the pressure of the hydraulic fluid to simulate pressure cycles in the chamber. The test stand controls the pressure with at least one source of high-pressure hydraulic fluid, the high-pressure being at an adjustable and constant level, at least one solenoid valve per chamber, receiving hydraulic fluid from the high-pressure source, and automatically drives each solenoid valve as a function of the pressure in the chamber and a set-point pressure, so that each solenoid valve feeds this chamber with hydraulic fluid the pressure of which is controlled at any time by the solenoid valve and simulates predetermined pressure cycles as a function of time.

    摘要: A thermal fatigue test stand for combustion engine cylinder heads. A cylinder head support having at least a cylinder head zone capable of being exposed to the engine combustion. At least one burner for directing a flame on the entire head zone. At least one heat flux sensor located in the cylinder head thickness at the zone to verify whether the heat flux produced by the flame is at least approximately in conformity with a predetermined value. The invention also concerns a method for calibrating such a test stand, and a method for testing cylinder heads. The invention is particularly useful for developing, both from a metallurgical and geometrical viewpoints, aluminum alloy cylinder heads.
