Abstract: A method for monitoring a gas sensor (14) which comprises two electrochemical measuring cells (20, 30) and which is arranged in an exhaust tract (10) of an internal combustion engine (11), wherein the sensor elements (20, 30) exhibit a substantially identical sensitivity towards a first gas component and a different sensitivity towards a second gas component and are insensitive towards further gas components. In an operating state in which an exhaust gas stream at the gas sensor (14) contains less of the second gas component than of the first gas component a concentration of the first gas component is calculated from each of the sensor signals from the sensor elements (20, 30) and a defect in a sensor element (20, 30) is deduced from the concentrations of the first gas component.

Abstract: Systems, apparatuses, assemblies, and methods for diesel exhaust fluid (DEF) dosing can include a body defining an injector adaptor inlet and an injector adaptor outlet; and an injector mount or interface extending from the body. The injector mount can be between the first and second ends of the injector adaptor. The injector adaptor outlet can define an area greater than an area of the injector adaptor inlet. In a side view of the injector adaptor, at a bottom side of the body, a first straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet, and at a top side of the body opposite the bottom side, a second straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet. The second straight line can be at an acute angle relative to the first straight line.
