Apparatus for regulating an internal combustion engine comprises a pressure-responsive transducer, preferably of the diaphragm type, adapted for connection with the intake duct of the engine to respond to air pressure therein, and mechanical output means responsive to that pressure for actuating a throttling device to oppose increase of pressure. The throttling device may be a normal throttling device, e.g. the throttling device on the carburetor of a motor vehicle, or it may be provided in addition thereto. With the apparatus fitted to a motor vehicle, a significant improvement in fuel economy is obtained by a wide class of drivers. |
