Abstract
A method of assessing the functioning of an EGR cooler of an EGR system in an internal combustion engine, wherein the EGR cooler can be selectively operated in a first and a second operating condition; and wherein the engine comprises at least one cylinder equipped with a pressure sensor. The assessment of the functioning of the EGR cooler is based on the variation of a combustion characteristic value depending on cylinder pressure (CA50), upon switching of the EGR cooler from a first to a second operating condition.
