Abstract
An automatic switching-off arrangement for the internal combustion engine of a motor vehicle comprises a sensor which senses the neutral position of the gear control lever or the idle running condition of the engine or the standstill condition of the vehicle. When the sensor detects such a condition a delay switch is energized which activates a switch-off means after a predetermined period so that the current supply to the ignition coil is interrupted or a half-compression device is operated and the engine is stopped. Thereby, fuel can be saved and pollution of the atmosphere can be reduced.
