Definitions

  • This invention relates to a device for restarting the engine of a vehicle when stalled, but which may also be used for starting the engine initially.
  • a device for restarting a stalled engine comprising means for connection to an oil pressure sensor of the engine to detect when the engine stalls, and to respond by energising the starter motor.
  • a device for restarting a stalled engine comprising means for connecting into the charging circuit of the vehicle electrical system to detect when the engine stalls, and to respond by energising the starter motor.
  • a device for starting an engine comprising means for detecting that the engine is at rest and means responsive to depression of the clutch, or displacement of the gear selector into neutral in the case of an automatic transmission, to energise the starter motor.
  • the means for detecting that the engine is at rest may for example respond to the oil pressure sensor and/or to the charging circuit of the vehicle electrical system.
  • the starter motor is automatically energised once the clutch is depressed (or the gear selector is shifted into neutral in the case of an automatic transmission).
  • the need to depress the clutch, or to shift the gear selector into neutral ensures that the transmission will be disconnected whilst the engine is cranked.
  • the deviced enables restarting of a stalled engine to be achieved in a simple manner; however the device can equally well be used to start the engine initially once the ignition has been turned on.
  • the device comprises a first relay REL 1 connected in an electrical path from an oil pressure sensor PS of the engine.
  • the device further comprises a second relay REL 2 connected in an electrical path of the battery charging circuit of the vehicle electrical system.
  • Contacts C1 and C2 of the respective relays are connected in series with further contacts CS on a path to the starter motor.
  • Contacts CS are coupled to the clutch, or to the gear selector in the case of an automatic transmission.
  • relay REL 1 In use, if whilst the ignition is switched on the engine stalls, the current through relay REL 1 from the oil pressure sensor will rise, so likewise will the current flowing through relay REL 2 to the battery charging warning light. As a consequence relays REL 1 and REL 2 are energised and the contacts C1 and C2 close. Then if the clutch is depressed (or the gear selector shifted into neutral) so as to close contacts CS, the starter motor will be energised over the path shown to automatically crank and restart the engine. It will be appreciated that this path to the starter motor is different from the path by which the starter motor is normally energised, typically by operation of the ignition key.
  • the oil pressure relay REL 1 has an additional pair of contacts CL which serve to latch this relay once a relay REL 3 has been energised. These contacts CL are connected in series with the ignition light via the switch CS on the clutch or transmission. Diode A prevents ignition current from illuminating the oil pressure light and diode B prevents current from the oil pressure sensor energising relay REL 3 which is intended to be energised only when the switch CS is closed, in which case its contacts C3 are closed to energise the starter motor if the oil pressure relay REL 1 has been latched.
  • the devices which have been described enable a stalled engine to be restarted in a simple manner.
  • the devices may also be used to start the engine initially once the ignition has been turned on.
  • the clutch (or gear selector) switch acts as a safety feature to prevent the engine from being cranked whilst the transmission is engaged.
