Operating space with a preferably thermally and acoustically insulating enclosure, and air louver arrangement which cooperates with said operating space

An operating space, particularly for a motor vehicle, which space is bounded by an enclosure, wherein more than half of the enclosure surface comprises an insulating lining material and/or more than half of the enclosure surface is formed from insulating lining material, the enclosure cooperating with an air intake louver system at an intake location, wherein the air intake louver system comprises an air intake passage opening and at least one air intake louver, the at least one air intake louver being adjustable between a passage position, in which the air-permeable flow cross section of the air intake passage opening is greater, so that air can be admitted through the air intake passage opening into the operating space, and a blocking position, in which the air-permeable flow cross section of the air intake passage opening is smaller, so that the amount of air per unit time which can be admitted into the operating space through the air intake passage opening is less than in the passage position.

An operating space, particularly for a motor vehicle, possibly for accommodating an internal combustion engine, which space is bounded by an enclosure, wherein more than half of the enclosure surface comprises a thermally and acoustically insulating lining material, and/or is formed from thermally and acoustically insulating lining material, wherein the operating space adjoins a tunnel which tunnel is employed possibly for accommodating a drive shaft and/or an exhaust pipe and/or a transmission component, wherein an air louver system comprises an air passage opening and at least one air louver, the at least one air louver being adjustable between an open position, in which the opening cross section of the air passage opening is larger, and a closed position, in which the opening cross section of the air passage opening is smaller, the air louver system being disposed in a transition region from the operating space to the tunnel, such that by actuating the at least one air louver an air flow and/or a sound propagation between the operating space and the tunnel can be influenced.

A motor vehicle having an operating space, particularly an engine compartment, the operating space is bounded by an enclosure, wherein more than half of the enclosure surface comprises an insulating lining material and/or more than half of the enclosure surface is formed from insulating lining material, the enclosure cooperating with an air intake louver system at an intake location, wherein the air intake louver system comprises an air intake passage opening and at least one air intake louver, the at least one air intake louver being adjustable between a passage position, in which the air-permeable flow cross section of the air intake passage opening is greater, so that air can be admitted through the air intake passage opening into the operating space, and a blocking position, in which the air-permeable flow cross section of the air intake passage opening is smaller, so that the amount of air per unit time which can be admitted into the operating space through the air intake passage opening is less than in the passage position.
