ABSTRACT:
In a motor car front end with an adjustable air-conducting means in the form of a nose apron which is arranged beneath the bumper and which may be tilted downwards about a transverse axis as a function of the velocity of travel, the nose apron (1) has a well rounded front edge (2) and its adjacent, tapering area is provided with reinforcing corrugations (3) and cooling air outlet ports (4). In its lowered position at high velocities of travel the nose apron (1) forms, relative to the road surface, a narrow Venturi cross-section (10) which causes an area of underpressure which results in a reduction of air resistance. In its raised position at low velocities of travel the nose apron (1) forms an ordinary angle of repose relative to the road surface and covers part of the radiator (22) from excessive throughflow.
