Abstract
This disclosure deals with a fuel supply system for an internal combustion engine, the supply system including injectors for injecting fuel into the combustion chambers of the engine, and hydraulic means for adjusting the timing of injection. In one form of the invention, a pump-distributor assembly supplies fuel sequentially to a plurality of injectors, and the hydraulic timing adjustment forms part of the assembly. In another form of the invention, the hydraulic timing adjustment is included in the injectors. The hydraulic timing adjustment responds to parameters of the engine, such as load and/or speed, for varying or holding constant the time of initiation of injection, and is quickly responsive to changes in the parameters.
