Abstract: 1404232 Stopping; ignition systems NISSAN MOTOR CO Ltd 12 Sept 1972 [10 Dec 1971 25 Feb 1972] 42296/72 Headings F1B and F1K When the ignition switch 10 is closed by the driver of a motor vehicle current flows through the normally closed relay switch 22 if the engine is cool since an engine temperature responsive switch is open. The primary winding 14a of the ignition coil is accordingly energized. The engine remains at rest so that an engine speed responsive switch 28 is maintained closed in the absence of a signal on the output of a switching unit (not shown). The relay coil 32 for the engine starter motor is consequently energized from the power source through the relay switch 22 whereby the engine is started up by the starter motor. When started the engine runs at a speed ranging from about 100 to 300 rpm so that the coil 28a of the speed responsive switch 28 is unexcited and accordingly its relay contacts 28b are closed. When the engine reaches a predetermined speed of say about 500 rpm an output is delivered from the switching unit so that the coil 28a of the switch 28 is energized and accordingly the relay contacts 28b are opened. This causes the starter motor to be shut down. When a predetermined temperature is reached by the engine the engine temperature responsive switch 24 closes and as a consequence the condition of the normally closed slow release relay switch 22 is dictated by the transmission gear responsive switch 26. The transmission gear responsive switch 26 is open except when the power transmission is in an uncoupled or neutral position and the normally closed relay switch 22 remains closed as long as the transmission is engaged. When the vehicle is stopped and the transmission is brought into the uncoupled or neutral condition the switch 26 closes thus the relay coil 22a of the switch 22 is energized through the ignition switch 10. The switch 22 is consequently opened after a predetermined time interval. The ignition is then cut out and the engine is stopped. When the gears in the transmission are engaged the switch 26 opens so that the relay coil 22a becomes de-energized and accordingly the normally closed relay switch returns to its closed position. The engine is started up by the starter motor when the ignition coil 14 is energized. In a modification the system comprises a vehicle speed responsive switch connected in parallel with an engine temperature responsive switch and a transmission gear responsive switch. The vehicle speed responsive switch is open when the vehicle speed is lower than a predetermined speed of for instance 4 km per hour. The vehicle speed responsive switch may be replaced by an accelerator position responsive switch and in another modification a clutch responsive switch may be connected in parallel with the accelerator responsive switch.
