ABSTRACT:
A system of converting a carbureted-spark ignited internal combustion engine to a fuel-injection-spark ignited mode of operation comprising a series of fuel injecting spark plugs for replacing the conventional spark plugs, a fuel manifold for the spark plugs connected to the fuel line in lieu of its connection with the carburetor and a distributor assembly for replacing the distributor cap and rotor of the distributor having a shaft section fixedly connected to the rotor shaft of the distributor, the shaft section having a drum mounted thereon for rotation therewith and for axial movement therealong in response to the movement of the speed control mechanism of the engine (in lieu of the carburetor response thereof), the drum cooperating with a ganged structure in the form of a replacement distributor cap to generate electrical signals resulting from the rotational movement of the drum which are transmitted to the fuel injection plugs as a function of engine speed and are varied in time or other characteristic as a result of the axial movement of the drum as a function of speed control mechanism position. The system includes provision for the cut off of the fuel injection signals in response to the release of the speed control mechanism to its idle position until the engine speed reduces to a value just above idle speed and a start up of the fuel injection signals in response to a depression of the speed control mechanism before reaching the aforesaid speed which closely correspond to the actual engine speed, by retarding or damping the return axial movement of the drum.
