Abstract

A pressure sensitive device (22) is fitted to the inlet manifold (1). When the vehicle is moving under its own inertia, and the accelerator pedal (8) is therefore not depressed, the depression in the inlet manifold (1) actuates the device (22) which closes the switch (33). Closing the switch (33) energises the solenoid (12). When the solenoid (12) is energised the butterfly valve (5) of the carburettor (2) is closed and a by-pass valve (14) is opened. The by-pass valve passes fuel free air to the engine so that no fuel is used under these conditions. When the accelerator pedal is depressed the solenoid (12) is deenergised and the engine resumes normal running.
