Abstract
Official abstract text for this publication.
An air intake system for an internal combustion engine may include an air intake channel, an exhaust gas return channel opening into the air intake channel, an exhaust gas cooler arranged in the exhaust gas return channel, a capture device, and a sensor. The capture device may capture cooling liquid from the exhaust gas cooler in the region of the opening point of the exhaust gas return channel into the air intake channel. The sensor may detect cooling liquid in the capture device.
First claim
Opening claim text (preview).
What is claimed is: 1 . An air intake system for an internal combustion engine, the air intake system comprising: an air intake channel, an exhaust gas return channel opening into the air intake channel, an exhaust gas cooler arranged in the exhaust gas return channel, a capture device for cooling liquid from the exhaust gas cooler disposed in the air intake channel in the region of the opening point of the exhaust gas return channel into the air intake channel, and a sensor for detecting cooling liquid in the capture device is assigned to said capture device. 2 . The air intake system as claimed in claim 1 , wherein the cooling liquid capture device includes a recess in the air intake channel. 3 . The air intake system as claimed in claim 2 , wherein the recess includes a depression below the opening point of the exhaust gas return channel into the air intake channel. 4 . The air intake system as claimed in claim 1 , wherein the sensor device comprises an ultrasonic sensor device. 5 . The air intake system as claimed in claim 4 , wherein the ultrasonic sensor device detects the presence of glycol. 6 . The air intake system as claimed in claim 4 , wherein the ultrasonic sensor device comprises an ultrasonic converter arranged on the one side of the cooling liquid capture device. 7 . A method for detecting a cooling liquid leak from an exhaust gas cooler arranged in an exhaust gas return channel of the air intake system of an internal combustion engine, the method comprising: capturing cooling liquid leaking from the exhaust gas cooler in a capture device arranged in the region of the opening point of the exhaust gas return channel into the air intake channel of the air intake system; detecting cooling liquid collected in the capture device; and confirming a cooling liquid leak on detection of cooling liquid. 8 . The method as claimed in claim 7 , wherein it is carried out when the internal combustion engine is not in operation. 9 . The method as claimed in claim 7 , wherein the cooling liquid is detected by means of an ultrasonic sensor system. 10 . The method as claimed in claim 7 , wherein the presence of glycol in the cooling liquid is detected.
