Abstract
The improved fuel injection system is for a rotary internal combustion engine having a housing within which a rotor is disposed for planetary rotary motion and which defines with the housing a plurality of combustion chambers. The improved fuel injection systems has a positive displacement fuel pump, such as of the plunger and barrel type, which is connected to deliver fuel to a fuel nozzle located to emit fuel into the combustion chambers upon actuation of the plunger. An actuating means, such as multi-profile cam is supported for rotation at a speed proportionate to rotor speed and disposed to effect reciprocative movement of the plunger. An automatic means, such as a pressurized fluid servomotor mechanism, is provided to effect a shifting of the cam relative to the pump plunger to change the speed of actuation of the plunger in proportion to rotor speed so that the duration of fuel injection into the combustion chambers at rotor speeds below high speed occurs during substantially the same amount of angular displacement of the rotor and for the same quantity fuel injected per revolution of the rotor as at high speed.
