This invention consists of an arrangement designed to deliver to the fuel-valve of a Diesel engine an amount of fuel that shall be strictly proportional to the load.
For this purpose suitable gearing is provided by means of which the fuel-pump is caused to make six complete strokes for each cycle of the engine. In this way the fuel-pump instead of delivering the full amount of fuel in one single stroke of large capacity, does so in six successive strokes of correspondingly less capacity.
In a modification of the above invention is described a pump operating on the same principle for supplying multiple-cylinder engines with fuel from a single pump, or from a combination or set of plungers.
A speed governor is provided which operates to control the fuel in such a manner that instead of cutting off the required amount of fuel for each working stroke of the engine, only one-sixth, or a multiple of one-sixth, of that amount will be cut off, depending upon the momentary speed variations.
