Abstract:
1. A sensor system for determining at least one parameter of an intake air mass flowing through a channel of an internal combustion engine, comprising: at least one sensor chip situated in the channel for determining the parameter of the intake air mass, wherein the sensor chip is accommodated in a sensor carrier which protrudes into the channel, the sensor carrier having a leading edge situated transverse to the flow of the fluid medium; and at least one vortex generator situated on the sensor carrier in the region of the leading edge, wherein the vortex generator is configured to form secondary flows in the form of vortices in the flowing intake air mass in the region of the sensor carrier, the vortex generator is configured to form secondary flows in the form of vortices in the flowing intake air mass in the region of the at least one sensor chip, and the secondary flows extend in a plane essentially perpendicular to the main flow direction of the intake air mass.
