Abstract
Disclosed herein is an apparatus which is adapted for controlling fuel flows for dual fuel compression ignition engines. The disclosed system includes a lag fuel governing system in conjunction with a lead fuel governing system which includes spontaneous motion metering means. The lag fuel governing system includes means for providing a first signal indicative of the position of the lead fuel metering means, which signal approximates total load on the engine; means for providing a second signal representative of a selected percentage of lead fuel relative to total load; means for controlling flow of said lag fuel to said engine, which flow causes movement of said lead fuel metering means; means for determining the difference between said first signal and said second signal, which difference is indicative of distance the lead fuel metering means must be moved to attain the selected percentage of lead fuel relative to total load; and means for causing operation of said means for controlling flow of said lag fuel to said engine to cause movement of said lead fuel metering means equal to the distance the lead fuel rack must be moved to attain the select percentage of lead fuel relative to total load.
