Description

FUEL INJECTOR FOR PRODUCING SHAPED INJECTION PULSES ABSTRACT A fuel injector, especially adapted for diesel engines, produces a fuel injection pulse having a predetermined time-variable flow rate. Preferably the injection pulse is ramp-shaped which approximates a linear function of time. A pressure chamber receives fuel at a substantially constant flow rate and an injection valve connected therewith opens in response to the pressure in the pressure chamber for delivering a fuel injection pulse to the combustion chamber. Means for absorbing a fluid pulse, in the form of an absorption chamber and flow restrictor, is connected with the pressure chamber to accept a ramp-shaped absorption pulse which is inversely related to the injection pulse. The fuel flow rate into the pressure chamber varies directly with engine speed and the injection pulse has a slope and amplitude which vary directly with engine speed; the absorbing means is provided with time constant adjusting means responsive to speed of operation so that the slope and amplitude of the absorption pulse vary directly with engine speed.
