COMBUSTION ENGINE

Abstract

The invention relates to an internal combustion engine (2) with at least one cylinder (1) having a combustion chamber (5) and with at least one exhaust gas flow path (9) extending from the combustion chamber (5). To detect oil entering the combustion chamber (5), the internal combustion engine (2) is provided with a device (11) for detecting and / or classifying oil-related combustion events, wherein the device (11) for detecting and / or classifying oil-related combustion events includes at least one CO2 sensor (12) communicating with the exhaust gas flow path (9), which is configured to detect a CO2 content in the exhaust gas of the exhaust gas flow path (9) of the internal combustion engine (2), and wherein the CO2 sensor is connected to a data acquisition device (13).
