Automatic control system for regulating or monitoring operation of a vehicle I.C. engine includes a pick-up device, conveniently an induction coil (10) to be mounted close to the engine driven alternator (8) or other generator, providing a pulsating electrical signal whose frequency is a function of engine speed. An electronic processing unit (14) responds to the signal to actuate one or more control or monitoring devices, for example a device (16) controlling operation of a diesel or other fuel distribution or feed pump (18) of the engine to cut off fuel feed when not required, e.g. when coasting with the throttle closed. Other devices operated by the unit may include a revolution counter or tachograph. |
