The air-mass flow sensor for determining the ambient pressure in the case of an internal combustion engine

摘要

With a mass air flow sensor into an intake tract (2) of an internal combustion engine (1) projecting air mass sensor (11) at one of the intake tract (2) to be secured to the housing (14, 16) is made, in which an absolute pressure sensor (12) for detecting an air pressure in the intake tract (2) is located, wherein a channel (18) the housing (14, 16) to the intake system (2) connects to the pressure equalization, characterized in that the absolute pressure sensor (12) on a printed circuit board (13) is arranged which, by means of a layer (20) is covered, the air pressure on the absolute pressure sensor (12) transmits.
