Embodiment Construction

[0031] figure 1 The internal combustion engine 10 according to the invention in the form of a vehicle engine is shown and has a crankcase 12 with a crankcase ventilation device 20 for ventilating engine lubricating oil contained in an oil guide area 30 of the crankcase 12.

[0032] The crankcase ventilation device KGE 20 is designed as a closed crankcase ventilation device, in which the oil guide area 30 (power chamber) of the crankcase 12 is connected to the engine suction pipe 40 through the ventilation pipe 22. The blow-by gas containing fuel vapor (which enters the power chamber through the piston ring) can be led back to the suction pipe 40 through the ventilation pipe 22, so that the pressure in the power chamber 30 can be kept constant and the frequent occurrence of cold start of the engine can be eliminated Pollution of the engine oil.

[0033] A measuring sensor 50 is arranged in the ventilation duct 22 for measuring at least one characteristic value of the ventilation air...

Abstract

The invention relates to an internal combustion engine having a crankcase ventilation with a vent line for venting a fuel-carrying portion of the crankcase, in which a measuring sensor for measuring is disposed in the venting line at least one information via an oil quality containing characteristic size of the vent gas. The invention further relates to a hybrid drive with such an internal combustion engine and a method for measuring the oil quality with such internal combustion engine.

Description

Technical field [0001] The present invention relates to an internal combustion engine with a crankcase ventilation device, which has a ventilation pipeline for ventilating a power room or other oil-conducting areas of the crankcase. In addition, the present invention also relates to a hybrid drive having such an internal combustion engine. According to a further point of view, the present invention relates to a method of evaluating the quality of engine oil in an internal combustion engine. Background technique [0002] For internal combustion engines, Blowby-Gase often occurs in the crankcase. Blowby-Gase enters the oil-conducting power chamber from the cylinder combustion chamber through the piston ring. The blow-by gas includes fuel vapor, combustion gas, etc., which cause pollution to the oil and increase the pressure in the crankcase, and therefore must be led out from the oil by a ventilation device in the form of a crankcase ventilation device . For closed ventilation e...
