Abstract
A system for variable engine compartment ventilation in a slim and compact unit with components used in non-related industries. The system can have at least one bank of movable louvers rotatably mounted within a louver frame for guiding a flow of air into a vehicle engine compartment; a motor to rotate the louvers with a motor gear formed on an output shaft rotatably connected in parallel to at least one helix cable by a helix cable drive gear and a louver pinion gear integral with each louver engaging the helix cable along its length; and a control unit for operating the assembly of movable louvers in response to an output signal from a vehicle communication bus. The output signal of the vehicle communication bus can be in response to input from an engine coolant temperature sensor or a vehicle speed sensor.
