Abstract
1305996 Treating exhaust NISSAN MOTOR CO Ltd 27 April 1970 [30 May 1969] 20147/70 Heading F1B In an anti-pollution system of a motor vehicle I. C. engine, the exhaust gases can be recirculated from exhaust pipe 12, Fig.1, through conduit 14, water separator 15, filter 16, restriction 14a, solenoid valve 17 and nozzle 18 into the inlet manifold 11. However, the electrical circuit of the solenoid 20, 21 incorporates a temperatureresponsive switch 36 which remains open when the engine is warming up so that the valve 17 remains closed to render the system inoperative when the engine is cold and few nitrogen oxides are present in the exhaust gases. The electrical circuit also includes an ignition switch 26, a switch 24 responsive to engine or vehicle speed, and a switch 23 responsive to inlet manifold vacuum. In an alternative embodiment, Fig.3 (not shown), the anti-pollution system comprises a unit (42) for recirculating the exhaust gases and an afterburner unit (43), the units being controlled by a double-acting temperatureresponsive switch (36a) so that the afterburner unit is operative during engine warm up to burn off hydrocarbons, and the exhaust gas recirculation unit is operative when the engine is up to temperature for reducing nitrogen oxides. The switch (36a) is of the bimetal type but may be replaced by a cam-actuated switch (36b), Fig.4 (not shown), responsive to the position of the carburetter choke valve (49) and thereby to engine temperature.
