Abstract

PURPOSE: To reduce the noise by a method wherein a hood is made up double to form a suction duct and a silencing louver arrangement is provided at the opening of a radiator guard and as well as a silencing arrangement is provided in front of the silencing louver arrangement.
CONSTITUTION: Air sucked from cooling air suction port 32 is introduced through a duct 22 into an engine room 26. Because an opening 28 is apart from the suction port 32 by the duct lined with sound absorbing material 34, the noise in the engine room 26 is reduced by being absorbed with the sound absorbing material 34 while diffused through the duct 22 to the outside of a car. Major part of the noisy air generated with a cooling fan 3 in the engine room is silenced with the silencing louver arrangement 14 provided at the opening of the radiator guard 8 and the also silenced with the sound absorbing material 46 of the radiator silencing arrangement 16.
