System for testing barrel of housing of combustion engine cylinder in commercial vehicle, has device displacing housing of cylinder with respect to heating and cooling elements to expose barrel of housing to heating/cooling element

摘要

The system (21) has an interior surface covered with a coating. A heating element (28) comprises a deviation device (34) or stopper for deviating the heat output from the heating element towards the interior surface of a barrel (25). A cooling element (29) comprises a tube (42) to eject coolant. A relative displacement device (32) displaces a housing (22) of a combustion engine cylinder with respect to the heating and cooling elements alternatively to expose the barrel of the housing to the heating element or to the cooling element. An independent claim is also included for a method for testing a barrel of a housing of a combustion engine cylinder.
