ABSTRACT:
This invention relates to a test stand for simulation of the exhaust flow of an internal combustion engine, comprisinga cylinder (36) and a base body (39) which is designed as a cylinder head and in which at least one exhaust port (41, 42) which is monitored by a charge cycle valve (43, 44) is provided for simulation, and/or, mapping, of a combustion chamber and a trough and/or cup (40) is also provided, whereby the charge cycle valve (43, 44) can be operated with the help of a valve lift switching [device],a control device for the valve lift shifting anda device for filling the cylinder (36) with compressed air.
