摘要： A centralized control system for coordinating a plurality of vehicular air-pollution preventive devices in such a manner as to minimize the harmful contents of the automotive exhaust gases. In a preferred embodiment, the system includes six air-pollution preventive devices; an ignition timing retarding device, an exhaust gas after-burning device, a fuel vapor trapping device, an exhaust gas recirculating device, an atmospheric air introducing device and a device for reducing hydrocarbon exhaust during deceleration. The system also includes five sensors; a vehicle speed sensor, an intake manifold vacuum sensor, a throttle opening sensor, an engine temperature sensor and an exhaust temperature sensor, and a controller adapted to determine the individual predetermined conditions of engine operation during which the air-pollution preventive devices are placed in operation, in accordance with electric signals supplied thereto from these sensors. The controller, upon determination of such conditions, operates to keep the devices operative.
