Thermoshock testing method for automobile engine exhaust manifold using simulated cylinder head for supplying exhaust manifold with heated pressurized air

摘要

The thermoshock testing method has a simulated cylinder head (10) used for supplying the exhaust manifold (1) with heated pressurized air, provided at a constant pressure from a pressurized air source (2) and divided into a number of partial streams, corresponding to the number of exhaust manifold inputs, for heating via respective burners (5), with individual control of the mass flow of the pressurized air for each burner. Also included are Independent claims for the following: (a) a device for thermoshock testing of an engine exhaust manifold; (b) a simulated cylinder head for a device for thermoshock testing of an engine exhaust manifold.
