Embodiment Construction

[0069] figure 1 An internal combustion engine 10 according to the invention is shown schematically, wherein only those elements which are potentially relevant in connection with the invention will be explained in detail below.

[0070] An intake section 12 is formed in the internal combustion engine 10 , via which fresh air from the environment can be conveyed in the direction of the combustion chamber 14 . A suction hood 18 is provided as the fluid-guiding component 16 of the suction section 12 . A compressor of an exhaust gas turbocharger 20 and a throttle valve 22 follow downstream of the suction bell 18 .

[0071] The area downstream of the compressor is referred to as pressure pipe 24 . A partial flow T branches off from the pressure line 24 at a branch 26 downstream of the exhaust gas turbocharger 20 , wherein the partial flow T is guided into the inflow channel 28 of the Venturi nozzle 30 . The outflow channel 32 of the Venturi nozzle 30 leads back into the suction h...

Abstract

The invention relates to an internal combustion engine having a fuel tank (36), a tank ventilation line (38) and a Venturi nozzle (30) disposed in a fluid-carrying component (16), wherein the Venturinozzle (30) has an inflow channel (28), an opening point (40) adjoining downstream of the inflow channel (28) with a fluid connection to the tank ventilation line (38), and an outflow channel (32) adjoining downstream of the opening point (40). In this case, an outflow section (48) of the Venturi nozzle downstream of the opening point (48) is surrounded by the component (16) in such a manner thata detection space (46) is formed around the outflow section (48), wherein the detection space (46) has at least one inlet opening (50) via which the detection space (46) can be pressurized and whereinat least one pressure sensor (34) for monitoring the pressure in the detection space (46) is provided.

Description

technical field [0001] The invention relates to an internal combustion engine according to the preamble of claim 1 with at least one Venturi nozzle (Venturi nozzle, sometimes referred to as Venturi nozzle) arranged in a fluid-conducting component. Background technique [0002] A turbocharger with a compressor is known from DE 10 2011 084 539 B3, wherein the compressor has a low-pressure inlet region connected to the low-pressure side of the suction line and a high-pressure side connected to the suction line high pressure outlet area. The turbocharger has a Venturi nozzle, which is arranged between a low-pressure inlet area and a high-pressure outlet area. In addition, a venturi nozzle is connected to the activated carbon filter in the tank ventilation line, allowing the activated carbon filter to be ventilated or regenerated. The Venturi nozzle can be integrated into the housing of the compressor or fixed there. No details are available from this document for the integrat...
