<p>Fuel injection apparatus employing continuously rotating rotors function to eject a fixed quantity of pilot into a cylinder in a fixed timing relationship relative to the starting of main fuel injection. Although these relationships are satisfactory when the ignition characteristics of the pilot and/or main fuels are within acceptable limits, deviation from such limits may give rise to emission and related problems. This invention is directed to overcoming the above problem by providing an adjustment mechanism (47) for infinitely adjusting the quantity of the injected pilot fuel (15) and the timing of such pilot injection in relation to the injection of main fuel (19). Rotors (29, 33) are employed for controlling the injection of both the pilot (15) and main (19) fuels.</p> |
