Method for detecting failure of function of charging setup positioning element of charging device for internal combustion engine in engine system, involves determining presence of mistake of function of charging setup positioning element

摘要

The method involves determining one or more indications to an internal combustion chamber pressure pattern in a cylinder (3) of an internal combustion engine (2) within a time domain, in which an exhaust valve of the cylinder is opened. The presence of a mistake of the function of a charging setup positioning element (63) is determined depending on the determined indications to the indications to the internal combustion chamber pressure pattern. The mistake of the function of the charging setup positioning element is recognized depending on an operating point of an engine system (1). An independent claim is included for a device, particularly a computing unit, for detecting a failure of the function of a charging setup positioning element of a charging device for an internal combustion engine in an engine system.
