Abstract
PURPOSE: To detect accurately the deceleration of engine and to perform properly the fuel cut and secondary air supply, by attaching ceramic pressure sensor onto accelerator link system of engine.
CONSTITUTION: Rod 201 is connected with throttle valve 102 of carburetor and at the top of this rod 201 is attached a ceramic pressure sensor 200. A rapid movement at the time of speed reduction is thus detected. The element 200 is connected with control circuit 300 and further this circuit 300 is electrically connected with electromagnetic valve 101, which is installed in fuel passage (which may be installed in a secondary air-passage though not illustratet in the figure). And when a high pressure exerts to the element 200, electromagnetic valve 101 closes the fuel passage (in case it is installed in the secondary air passage, the passage is opened).
