Abstract

1491442 Road-vehicle signalling-apparatus SIMMS GROUP RESEARCH & DEVELOPMENT Ltd 16 Oct 1974 [26 Oct 1973] 49965/73 Heading G4Q A road vehicle engine speed sensor 10 is coupled to a fuel control circuit via line 17 and to a transistor circuit for energization of a relay 34 for closing switch 38 to cause illumination of lamps 39 when a fault in the engine or its fuel control system causes a reduction in the speed of the vehicle. In the embodiment the engine is a compression-ignition type and switch 40 is the usual brake lamp switch; the invention may be applied to gas turbine engined vehicles, where the gas temperature at the turbine entry is sensed, or for the ignition system of a sparkignition engine.
