Title:
TEST STAND FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO2001069195
Kind Code:
A9
Abstract:
The invention concerns a test stand for elements of an internal combustion engine cylinder head comprising at least a combustion or pressure chamber (29), means supplying (10) a hydraulic fluid into the combustion or pressure chamber, and means controlling said fluid pressure so as to simulate pressure cycles in the combustion or pressure chamber. The control means comprise at least a high pressure source (6) of hydraulic fluid, at least one solenoid valve (7) per combustion or pressure chamber to supply said combustion or pressure chamber with hydraulic fluid from the high pressure source, at least a pressure sensor (8) for measuring the pressure in each combustion or pressure chamber, and control means (9) for controlling each solenoid valve on the basis of the pressure measured in said combustion or pressure chamber and a setpoint pressure.
